Syntheses, structures, and luminescence of two Zn(II) coordination polymers based on 5-(4-imidazol-1-yl-phenyl)-2H-tetrazole and carboxylates

Three new metal coordination polymers of bifunctional imidazolate/tetrazolate bridges: the only example of a three-dimensional framework based on rare [Co4(μ3-OH)2(μ2-Cl)2]4+ mixed oxo-chloro-clusters

Three new metal coordination polymers [Ni(μ₂-L)₂(H₂O)₂]_n(1, HL = 1-tetrazole-4-imidazole-benzene), [Co(μ₂-L)₂]_n (2), and [Co₄(μ₃-OH)₂(μ₂-Cl)₂(μ₅-L)₂(μ₂-L)₂]_n·7nH₂O (3) were hydrothermally synthesized and structurally characterized. 1 displays a neutral [Ni(μ₂-L)₂(H₂O)₂]_n chain built up from the Ni²⁺ ions bridged by deprotonated L⁻ ligands, while 2 shows another rare neutral [Co(μ₂-L)₂]_n chain based on Co²⁺ ions connected by two different coordination modes of the L⁻ ligand. 3 exhibits a rare [Co₄(μ₃-OH)₂(μ₂-Cl)₂]⁴⁺ mixed oxo-chloro-cluster-based three-dimensional framework with large elliptical channels, which are filled by unprecedented chilopod [(H₂O)₇]_n chains. Both 1 and 2 show antiferromagnetic behavior, while 3 exhibits unusual spin-canting.

The interconnection of rare [Co₄(μ₃-OH)₂(μ₂-Cl)₂]⁴⁺ mixed oxo-chloro-clusters and bifunctional bridges gives a new three-dimensional framework with unusual spin-canting behavior.

A novel 3-D photoluminescent cuprous chloride polymer based on bifunctional imidazolate/tetrazolate bridges

The interconnection of rare [Cu₂Cl]⁺cations and multidentate 1-tetrazole-4-imidazole-benzene bridging ligands gives a novel 3-D cuprous chloride polymer with a bimodalfsc-3,5-Cmce-2 topological type (L⁻ligand and Cu⁺ion: orange and blue).
