Structure Characterizations and Electrochemical Property of a Novel One-dimensional Coordination Polymer [Cd(N-MeIM)_2(SCN)_2]_n

A novel cadmium(Ⅱ) isothiocyanate complex [Cd(N-MeIM)2(SCN)2]n (N-MeIM=N-methylimidazole) has been prepared and characterized by spectroscopic analysis and crystallographic method. The title compound crystallize in the Triclinic system, space group P1, with lattice parameters a=0.589 50(12) nm, b=0.785 70(16) nm, c=0.882 00(18) nm, α=110.98(3)°, β=106.49(3)°, γ=95.08(3)°, and Z=1. The title compound exhibits an infinite chain structure in which each pair of Cd atoms is bridged by two η-1,3-SCN- groups. The unique Cd atom lies on an inversion centre and the coordination sphere is completed by two N-MeIM N atoms to form a CdS2N4 octahedron. The polymeric chains are further extended into three-dimensional network via π...π stackings interactions between the imidazole rings. The cyclic voltammetry behaviors of the compound on glass carbon electrode showed a typical irreversible process. CCDC: 265283.
