Synthesis and Crystal Structures of Two Coordination Polymers Based on a New N-Donor Aromatic Ligand

Two new coordination polymers Co(C9H7N7)(SO4)(H2O) (I) and Cd(C9H6N7)2·H2O (II), where C9H7N7 is 4-(5-(1H-1,2,4-triazol-1-ylmethyl)-1,2,4-triazol-3-yl)pyridine, are synthesized through hydrothermal reactions and structurally determined by single-crystal X-ray diffraction analyses. The results reveal that compound I belongs to the triclinic space group P-1 with a 1-D chain structure, whereas compound II belongs to the monoclinic space group C2 with a 2D layer structure. Hydrogen bonds play an important role in the construction of 3D structure of the two compounds.
