“…[16][17][18][19] An fdc (fdc = 1,1'-ferrocenedicarboxylate ion) ligand as a kind of polycarboxylates has attracted attention not only in the field of coordination chemistry but also in the field of organometallic chemistry. [20][21][22][23] During our efforts to explore the molecular interactions between metallomacrocycles and polycarboxylate ligands in zinc(II) and cadmium(II) tetraazamacrocycles containing bridging polycarboxylate ligands, we successfully synthesized and structurally characterized two 1D zinc(II) coordination polymers 1 and 2, where each ferrocenyl of bridging fdc ligands adopts different conformation, and a macrocyclic cadmium(II) dimer 3.…”

Coordination polymers on the basis of the assembly of metal ion "connectors" and multidentate ligand "linkers" have been of great interest due to their intriguing architectures and versatile applications.1-9 Metallotetraazamacrocycles bearing equatorial amines coordinated to the central metal ions and axial sites opened for incoming "linkers" are good "connectors" as building blocks for the construction of coordination polymers. 10-15Among multidentate ligands, polycarboxylates have been widely used as "linkers" due to their versatile coordination modes toward metal ions. [16][17][18][19] An fdc (fdc = 1,1'-ferrocenedicarboxylate ion) ligand as a kind of polycarboxylates has attracted attention not only in the field of coordination chemistry but also in the field of organometallic chemistry. [20][21][22][23] During our efforts to explore the molecular interactions between metallomacrocycles and polycarboxylate ligands in zinc(II) and cadmium(II) tetraazamacrocycles containing bridging polycarboxylate ligands, we successfully synthesized and structurally characterized two 1D zinc(II) coordination polymers 1 and 2, where each ferrocenyl of bridging fdc ligands adopts different conformation, and a macrocyclic cadmium(II) dimer 3. Thus, two Cp (Cp = cyclopentadienyl) rings of fdc ligands in 1 are mutually staggered, whereas they are eclipsed in 2. The cadmium(II) cyclams with folded macrocycles are bridged by an oxalate ligand in 3. In this report we describe the details of the synthesis and structures of 1-3.

C22H14N2N1O9, triclinic, PI (no. 2), a = 9.589(5) A, b= 10.144(7) A, c = 11.312(5) A, a = 87.11(2)°, β = 72.38(2)°, γ = 64.96(2)°, V= 946.3 Ä 3 , Z= 2, Rgt(F) = 0.035, wRietfF 2 ) = 0.085, T= 173 K. Source of materialSky blue block crystals of the title compound were synthesized by a hydrothermal method. All chemicals were of analytical purity grade and were used without further purification. A mixture of NiCh · 6H2O (1 mmol, 0.238 g), 1,2,4,5-benzenetetracarboxylic anhydride (1 mmol, 0.218 g), 1,10-phenanthroline monohydrate (1 mmol, 0.198 g), NaOH (2 mmol, 0.080 g) and distilled water (5 ml) was located into a 30 ml Teflon-lined reactor and heated at 160 °C for 4 days. After cooling to room temperature at ca. 5 K/h, blue block crystals were isolated and washed with water and ethanol for three times, then dried in ambient. Elemental analysis: found -C, 52.02 %; H, 2.84 %; N, 5.54 %; calc. for C 2 2Hi4N2Ni09 -C, 51.91 %; H, 2.77 %; N, 5.50 %. DiscussionThe self-assembly of metal ions with aromatic carboxylates is a rapidly developing research field of modern coordination chemistry, because of the aggregation of metal ions and these carboxylate ligands in versatile binding modes, such as monodentate, chelating bidentate, bridging bidentate and bridging tridentate. Hereby, 1,2,4,5-benzenetetracarboxylic acid (H4TCB) is a good bridging ligand, and numerous complexes with H4TCB anions have been prepared, such as that of Co(II) [1][2][3], Νϊ(Π) [4,5], ΊΊ(Ι) [6], Cu(ü) [4,7,8], Ζη(Π) [9]. Especially, the metal-1,10-phenanthroline (phen) system has been well studied and displays a diversity of structures. The title compound, [Ni 2 (H2TCB)2(phen)2(H20)2]n, forms a 2D polymer. The Ni atom is six-coordinated by four Ο atoms from three pyromellitate anions (H2TCB) and one water molecule, and two Ν atoms from a phen ligand.
