Abstract

Using 4-substituted tetrazole–benzoate ligands, 4-aminophenyl-1H-tetrazole (HL1) and 4-carboxyphenyl-1H-tetrazole (H2L2), five metal–organic coordination polymers formulated as [Co3(OH)2(L1)4(H2O)2]2n (1), [Zn(L1)2]n (2), [Ag(L1)]n (3), [Co(L2)(H2O)]n (4) and [Pb(L2)]n (5) have been hydro(solvo)thermally synthesized and structurally characterized by single-crystal X-ray diffraction. Due to the effects of the different metal centers and the substituted groups of ligands, such as –NH2 and –COOH, compounds 1–5 demonstrate different characteristics. Compound 1 features a 3D framework with a rare (3,6)-connected rtl (rutile) topology. Compound 2 crystallizes in a noncentrosymmetric space group P[4 with combining macron]n2 and manifests a 3D non-interpenetrated dia framework. Compound 3 shows a 2D layer structure with 3-connected 4·82-fes topology. Compound 4 exhibits a uninodal 8-connected body-centered cubic (bcu) net with a Schläfli symbol of 424·64. Compound 5 possesses a 3D framework with 5-connected 46·64-bnn (hexagonal boron nitride) topology. Luminescent studies show that compounds 1–5 exhibit good solvent-dependent properties, especially in their response towards acetonitrile, carbon tetrachloride and acetone molecules. In addition, compound 1 shows spin-canted antiferromagnetism at low temperature.
