摘要：
Two novel coordination polymers with molecular structures (2MI)(+)[Zn(2MI)Cl-3](1) and (2MI)+NO3- (2) based on ligand 2-methylimidazole (2MI) were synthesized under solution method. Compound 1 crystallizes in the monoclinic system, space group Cc with a = 7.489(2), b = 13.448(4), c = 13.983(4) angstrom, beta = 98.402(2)degrees, Z = 4 and V = 102.246(2) angstrom(3). Compound 2 crystallizes in the orthorhombic system, space group pnma with a = 14.296(3), b = 6.3180(12), c = 7.3862(13) angstrom, beta = 90 degrees, Z = 4 and V = 667.1(2) angstrom(3). Dielectric measurements show compounds 1 and 2 have reversible dielectric anomalous behaviors with variation frequencies at different temperature.
