Abstract

A novel cadmium coordination polymer, [Cd(tmb)(Cl)(CH3OH)]n (1) (Htmb = 2-(1H-triazol-1-ylmethyl)-1H-benzoimidazole), has been solvothermally synthesized and structurally characterized by IR, elemental analysis, thermogravimetric analysis and single-crystal X-ray diffraction. 1 crystallizes in the trigonal system, R[3 with combining macron], with a = 22.496(3), b = 22.496(3), c = 14.870(3) Å, V = 6516.7(19) Å3 and Z = 18. Interestingly, 1 possesses a unique three-dimensional framework, based on the dodecanuclear Cd(II) macrocycles, and contains two different types of pseudo-helical chain with left- and right-handed characters, which present alternately along the metallamacrocycle. In addition, 1 exhibits an enhanced fluorescent intensity at 77 K in comparison to its emission at room temperature.
