摘　　要：Three copper（Ⅱ） coordination polymers [Cu（mbtz）2（NCS）2]n （1）, [Cu（mbtz）2Cl2]n （2） and [Cu（mbtz）（btec）0.5]n （3） （mbtz= 1,3-bis（1,2,4-triazol-1-ylmethyl）benzene, btec= 1,2,4,5-benzenetetracarboxylate） were synthesized. In 1 and 2, two mbtz ligands are wrapped around each other and are held together by Cu（Ⅱ） atoms to form one-dimensional double chain. In 3, each btec ligand connects four Cu（Ⅱ） atoms through its four carboxylate groups, resulting in a planar two-dimensional [Cu（btec）0.5]n network. The Cu（Ⅱ） atoms are further coordinated mbtz ligands to fulfil their coordination geometry and construct new [Cu（btec）0 .5（mbtz）]n network. 2 and 3 further form the three-dimensional network through the π…π stacking interactions between the mbtz ligands. The thermal stabilities of 1, 2 and 3 were measured.Three copper（Ⅱ） coordination polymers [Cu（mbtz）2（NCS）2]n （1）, [Cu（mbtz）2Cl2]n （2） and [Cu（mbtz）（btec）0.5]n （3） （mbtz= 1,3-bis（1,2,4-triazol-1-ylmethyl）benzene, btec= 1,2,4,5-benzenetetracarboxylate） were synthesized.
