摘　　要：Two novel coordination polymers with molecular structures（2MI）＋[Zn（2MI）Cl3]-（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） , β=98.402（2）°, Z=4 and V=102.246（2） 3. Compound 2 crystallizes in the orthorhombic system, space group pnma with a=14.296（3）, b=6.3180（12）, c=7.3862（13） , β=90°, Z=4 and V=667.1（2） 3. Dielectric measurements show compounds 1 and 2 have reversible dielectric anomalous behaviors with variation frequencies at different temperature.Two novel coordination polymers with molecular structures（2MI）＋[Zn（2MI）Cl3]-（1） and（2MI）＋NO3-（2） based on ligand 2-methylimidazole（2MI） were synthesized under solution method.
