“…Reaction of nickel(II) acetate with o-phthalic acid and excess of pyridine in water resulted in the high yield formation of [Ni(Pht)(Py) 2 [1,3,8,14,15,28] and carboxylate complexes [37][38][39]. The infrared spectra also show broad bands in the 3541-3071 cm À1 region, which can be assigned to water molecules.…”

“…As a result of the two ortho-carboxylic groups, the ligand has the capacity to chelate as well as to bridge up to seven metal centers at once [1, Scheme 1] forming mono-and polynuclear complexes. Based on analysis of the crystal structures of phthalates extracted from the Cambridge Structural Database (CSD) [2] in our previous report [1], we have shown that the phthalate ligand can adopt 26 coordination modes with metal atoms in the complexes. Moreover, both monodeprotonated HPht À anions and neutral H 2 Pht molecules are able to co-exist with fully deprotonated Pht 2À residues of acid in crystals, leading to some unexpected architectures.…”

Three new coordination compounds, [Ni(Pht)(Py) 2 (H 2 O) 3 ] (1), [Ni(Pht)(b-Pic) 2 (H 2 O) 3 ] AE H 2 O (2) and [Ni(Pht)(1-MeIm) 2 (H 2 O) 3 ] (3) (where Pht 2À = dianion of o-phthalic acid; Py = pyridine, b-Pic = 3-methylpyridine, 1-MeIm = 1-methylimidazole), have been synthesized and characterized by IR spectroscopy and thermogravimetric analysis. Crystallographic studies 1-3 reveal that each Ni(II) center has a distorted octahedral geometry being coordinated by two nitrogen atoms of aromatic amines, one oxygen atom from a carboxylate group of a phthalate ligand and three water molecules. Pht 2À anions act as monodentate ligands, while the remaining uncoordinated carboxylate oxygen atoms participate in the formation of hydrogen bonding. The uncoordinated oxygen atoms form hydrogen bonds with the coordinated water molecules from adjacent complexes creating a centrosymmetric dimer unit. Further, these dimer units are connected by O-HÁ Á ÁO hydrogen bonds in double-chains. Depending on the nature of aromatic amines, the arrangement of these double-chains differs. The double-chains are held together only by van der Waals interactions in 1. In contrast, in 2 these chains form layers by p-p interactions between antiparallel molecules of b-Pic as well as by p-p interactions between b-Pic and Pht aromatic rings. In complex 3, the double-chains are knitted together via C-HÁ Á ÁO hydrogen bonds between the methyl group of 1-MeIm and the coordinated carboxylate oxygen atom of Pht, as well as p-p contacts involving antiparallel 1-MeIm cycles. The thermal dependence of the magnetic susceptibilities for compounds 1 and 2 shows a weak antiferromagnetic interaction between the two Ni 2+ ions of the hydrogen bonded dimers. For compound 3, a ferromagnetic interaction could be observed. Modeling the experimental data with MAGPACK MAGPACK resulted in: g = 2.22, |D| = 4.11 cm À1 and J = À0.29 cm À1 for compound 1, g = 2.215, |D| = 3.85 cm À1 and J = À0.1 cm À1 for compound 2 and g = 2.23, |D| = 4.6 cm À1 and J = 0.22 cm À1 for compound 3.

“…In particular, coordination polymers with terephthalic [2], isophthalic [3] and phthalic acids have been extensively studied. Among these isomeric forms the o-phthalate ligand, with two carboxylic groups in ortho-position, can adopt the most diverse bonding modes (26 coordination modes [32]) in metal complexes. As a result, it can be expected that more complicated and unexpected architectures leading to new properties and reactivity can be constructed.…”

“…We have recently become interested in the synthesis of 3d-coordination compounds with the phthalate and N-containing ligands. Copper(II) [32][33], cobalt(II) [32,34], and zinc(II) [32,[35][36] coordination polymers have been reported so far. In an extension of the study here we report on the synthesis, crystal structure and magnetic properties of new cobalt(II) and copper(II) mixed-ligand coordination polymers [M(Pht)(4-MeIm) 2 (H 2 O)] n (where Pht 2À =dianion of o-phthalic acid, 4-MeIm=4-methylimidazole).…”

New coordination polymers [M(Pht)(4-MeIm) 2 (H 2 O)] n (M=Co (1), Cu (2); Pht 2À =dianion of o-phthalic acid; 4-MeIm=4-methylimidazole) have been synthesized and characterized by IR spectroscopy, X-ray crystallography, thermogravimetric analysis and magnetic measurements. The crystal structures of 1 and 2 are isostructural and consist of [M(4-MeIm) 2 (H 2 O)] building units linked in infinite 1D helical chains by 1,6-bridging phthalate ions which also act as chelating ligands through two O atoms from one carboxylate group in the case of 1. In complex 1, each Co(II) atom adopts a distorted octahedral N 2 O 4 geometry being coordinated by two N atoms from two 4-MeIm, three O atoms of two phthalate residues and one O atom of a water molecule, whereas the square-pyramidal N 2 O 3 coordination of the Cu(II) atom in 2 includes two N atoms of N-containing ligands, two O atoms of two carboxylate groups from different Pht, and a water molecule. An additional strong O-H?O hydrogen bond between a carboxylate group of the phthalate ligand and a coordinated water molecule join the 1D helical chains to form a 2D network in both compounds. The thermal dependences of the magnetic susceptibilities of the polymeric helical Co(II) chain compound 1 were simulated within the temperature range 20-300 K as a single ion case, whereas for the Cu(II) compound 2, the simulations between 25 and 300 K, were made for a linear chain using the Bonner-Fisher approximation. Modelling the experimental data of compound 1 with MAGPACK resulted in: g ¼ 2:6; |D|=62 cm À1. Calculations using the Bonner-Fisher approximation gave the following result for compound 2: g ¼ 2:18; J ¼ 20:4 cm À1 .

An easy way of producing three-dimensional metal-organic coordination polymers involving zinc(II) benzene-dicarboxylates is reported. The reaction of zinc oxide with benzene dicarboxylic acids in water yielded the expected hydrated zinc dicarboxylates. These zinc compounds were then suspended in dimethylsulfoxide and heated to above 100 • C for a couple of hours; the solutions were allowed after filtration to cool down to eventually deliver crystalline compounds displaying complex zeotype structures. The crystal structure of the title compound, [Zn 2 (ip) 4 (DMSO) 2 (H 2 O)·3 DMSO] n (ipH 2 = isophthalic acid = 1,3-benzenedicarboxylic acid, DMSO = dimethylsulfoxide), is reported for the first time and shows a three-dimensional network where octahedrally and tetrahedrally coordinated zinc atoms (present in a 1 : 1 ratio) are linked by bridging isophthalate ligands. The complex coordination network exhibits a remarkable channel structure along the z-axis. The related zinc terephthalate-DMSO complex was similarly prepared and the crystal structure determination revealed an already documented zeotypic structure: [{Zn 4 (OH) 2 (tp) 3 (DMSO) 4 } 2H 2 O] n (tpH 2 = terephthalic acid = 1,4-benzenedicarboxylic acid). Weak interactions as well as hydrogen bonds involving water molecules and carboxy groups play a major role in the formation of these complex three-dimensional networks. In comparison, the zinc 1,2-benzene-dicarboxylate-DMSO complex could not be isolated, even under more drastic conditions. The higher symmetry of the coordination network found in the zinc terephthalate-DMSO complexes was incidentally corroborated by 13 C CP/MAS spectroscopy.
