“…These include mononuclear Mn(III) and Mn(IV) complexes, binuclear Rh 26 and Ir compounds, and a series of binuclear 4,5-dicarboxyimidazolate-bridged Mn compounds isolated in three different oxidation states, Mn III Mn III , Mn III Mn IV , and Mn IV Mn IV . , Species of higher nuclearity, such as a cyclic tetramer, have been proposed to be synthesized from the reactions of oxovanadium(IV) with 4,5-dicarboxyimidazole, although none has been isolated . Recently, two types of one-dimensional polymeric chains have been reported: one involves complexes of Mn(III) ions with 4,5-dicarboxyimidazole that are held together via intermolecular hydrogen bonds, and the other is composed of [Mn(phen)] 2+ units (phen = 1,10-phenanthroline) and 4,5-dicarboxyimidazole, with the latter acting as a μ 2 -bridging ligand between two neighboring Mn(II) centers . Three-dimensional frameworks supported by H bonds have also been constructed by 4,5-dicarboxyimidazole and 4-carboxy-1-hydroxymethylimidazole in combination with various bivalent metal ions.…”

Two polydentate ligands of the family of dicarboxyimidazoles, H(2)MeDCBI (= 4,5-dicarboxy-1-methyl-1H-imidazole) and H(3)DCBI (= 4,5-dicarboxyimidazole), have been used in reactions with the [Fe(3,5-(t)()Bu(2)salpn)](+) species {3,5-(t)Bu(2)salpn = the dianion of 1,3-bis-[(3,5-di-tert-butylsalicylidene)amino]propane} to synthesize selectively complexes of different nuclearities. Four complexes have been synthesized: the mononuclear complex [Fe(3,5-(t)Bu(2)salpn)(HMeDCBI)] (1), the two binuclear but topologically different complexes [Fe(3,5-(t)Bu(2)salpn)(MeDCBI)Fe(3,5-(t)Bu(2)salpn)] (2) and {[Fe(3,5-(t)Bu(2)salpn)](2)(HDCBI)} (3), and the trinuclear complex {[Fe(3,5-(t)Bu(2)salpn)](2)(DCBI)Fe(3,5-(t)Bu(2)salpn)} (4). The structures of these complexes have been determined by X-ray crystallography. Variable-temperature direct-current magnetic susceptibility measurements were conducted for all compounds to obtain information about their electronic structure and to investigate the extent of magnetic communication among the Fe(III) centers. The results of these measurements allowed us to correlate the different structural motifs with the possible magnetic interactions that arise in multinuclear complexes of dicarboxyimidazoles. For 1, the room-temperature chi(M)T value reveals an S = (5)/(2) ground state. The data for the binuclear but topologically different complexes 2 and 3, and the trinuclear complex 4 suggest that weak intramolecular antiferromagnetic interactions are present, with interaction parameters ranging from -3.6 to -5.1 cm(-1). Differences in the extent of the magnetic communication between the metal centers through the two different interaction pathways of the ligands MeDCBI and DCBI (either through the imidazole ring or through the carboxylate groups) have been observed in complexes 2-4 that can be explained by the structural differences observed in the crystal structures of these compounds (the separation of the metal centers and the coplanarity of the metal ion orbitals with the pi system of the ligands). Cyclic voltammetry measurements for the mononuclear compound 1 show an irreversible reduction wave that is attributed to Fe(3+) + e(-) --> Fe(2+). The electrochemical behavior of the multinuclear complexes 2-4 is more complicated; however, it indicates that there is a degree of electronic communication between the Fe(III) centers.

“…Remarkably, herein we report the synthesis of two new 3 d -4 f heterometallic coordination polymers (HCP) based on Ce III and two different 3 d cations, Co II or Cu II , by using a single organic linker, the bifunctional ligand 1 H -imidazole-4,5-dicarboxilyc acid (H 3 IDC). H 3 IDC has proven to be an excellent ligand to construct coordination polymers with intricate and beautiful structures, using different metals cations such as from n s block, − 3 d , − and 4 d transition cations ,, and with lanthanide cations. , The versatility of this ligand also relies on the multiple anionic species that can be generated: H 2 IDC – , HIDC 2– , and IDC 3– , which not only allows the balance of charges of the cations but also gives multiple coordination sites with different coordination capabilities. Nevertheless, 3 d -4 f HCPs using this ligand as organic linker are still scarce.…”

In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on CeIII and containing CoII or CuII cations, assembled by the bifunctional ligand 1H-imidazole-4,5-dicarboxylic acid, [Ce(H2O)2(HIDC)Co(IDC)]·H2O CoCe and [Ce(H2O)2(H2IDC)Cu(H2O)(IDC)Cu0.2(H1.6IDC)] CuCe. Compound CoCe was obtained under one pot hydrothermal synthesis, while CuCe was synthesized by a step-by-step synthesis using the metalloligand [Cu(H2IDC)2(H2O)2] Cu1, as precursor. From a structural point of view, CoCe presents an intrincated 3D structure, in which alternating Λ-Δ chiral CoII chains can be observed, which are assembled by discrete CeIII fragments, giving rise to the 3D structure. Meanwhile, CuCe presents a structure formed by [Cu2Ce2] heterometallic chains, partially assembled by CuII cations in a 2D structure. Magnetic properties reveal that both CoCe and CuCe present a global antiferromagnetic behavior, dominated by the interaction between CoII-CoII or CuII-CuII entities connected by μ2-κN,O-κO′′′,N′ bridges, belonging to H3IDC anionic derivatives. Moreover, a weak ferromagnetic phenomenon was found in compound CoCe, corroborated by hysteresis loops and ac magnetization.

C 19H19CuN3O5, orthorhombic, Fdd2 (no. 43 DiscussionSupramolecular framework has received increasing attention over the past decade, attributing to the structural diversity and potential applications in the field of molecular magnetism, biological redox active systems [1][2][3], selective separation and catalysis [4][5][6][7][8][9][10][11][12]. Among them, building units based on tridentate terpyridine-type ligands and octahedrally coordinated metal ions are of special interest as they reveal a variety of interesting structural and physicochemical properties [13]. In the crystal structure of title compound, the Cu(II) ion is pentacoordinated by three N atoms of the tridentate chelating terpyridyl unit and two O atoms from two different acetate groups. The three d(Cu-N) fall in the range 1.961(2) -2.051(2) Å, and the two d(Cu-O) fall in the range 1.974(2) -2.111(3) Å. The N−Cu−N angles vary from 78.94(9)°to 158.33(9)°. These are comparable to literature values [14]. The coordination polyhedron is a distorted square pyramid with the O1 atom at the apical position. Through the intermolecular hydrogen bonds of the lattice water molecules and the oxygen atoms from two different acetate groups with O−H···O (2.699 Å, 166.09°; 2.819 Å, 146.42°) the adjacent mononuclear units are linked into a 1D chains running along [001]. Furthermore, the neighboring 1D chains are inter-linked to form the planes through the interchain C−H···O hydrogen bonds (3.301 Å, 139.46°) and the weak faceto-face p-p interactions of the terpyridine ring belonging to adjacent mono-nuclear units with distances of about 3.772 Å.
