Abstract

Three new coordination polymers containing 2-(4-pyridyl)thiazole-4-carboxylate (pytac) with cobalt, vanadium oxide, or cadmium iodide have been synthesized solvothermally, isolated, and characterized by single-crystal X-ray diffraction and powder X-ray diffraction. [Co3(pytac)6](H2O)8 (1), which crystallizes in the space group C2/c (a = 24.1418(8) Å, b = 17.5088(6) Å, and c = 14.4562(5) Å, β= 96.0390(10)°), has 1D hexameric water channels that constitute a 14.4% of the unit cell volume. Co3(pytac)2(H2O)4V4O12 (2), which crystallizes in the space group P1¯ (a = 8.6591(5) Å, b = 9.0044(5) Å, and c = 10.6495(6) Å, α = 67.1160(10)°, β = 82.6880(10)°, and γ = 83.9880(10)°), is an extension of the former in that it contains Co(H2O)4V4O12 in addition to the Co-only 2D layers. [CdI(pytac)(H2O)]·H2O (3), which also crystallizes in the space group P1¯(a = 8.2376(4) Å, b = 8.4859(4) Å, and c = 11.1261(5) Å, α = 68.2020(10)°, β = 77.5610(10)°, and γ = 69.1230(10)°), exhibits structural characteristics similar to 2, in that both contain 1D chains where the pytac ligand simultaneously engages in three different coordination modes: chelating, single bond coordination, and μ-2 bridging between two metal centers via carboxylate oxygen atoms.
