中文摘要：

选用2，6-H2ndc为主配体，344-pytpy为辅助配体，在水热条件下与Cu（NO3）2·2．5H2O反应，得到了1个新的配合物[Cu2（2，6-ndc）2（344-pytpy）（H2O）2DMF]，其中2，6-H2ndc=2，6-萘二羧酸，344-pytpy=2，6-二（4′-吡啶基）-4-（3′-吡啶基）吡啶，X射线单晶衍射分析表明，Cu1与2个羧基氧原子，1个氮原子，2个水分子配位，而Cu2中1个DMF配位取代了Cu1中的1个水分子，两者均为五配位四面体构型，Cu1、Cu2通过含氮辅助配体桥连，形成一维梯状结构．该配合物具有良好的热稳定性．

英文摘要：

The main ligand H2ndc and auxiliary ligand 344-pytpy reacted with Cu（NO3）2·2.5H2O under hydrothermal conditions to afford a novel Cu（ Ⅱ ） complex [Cu2（2,6-ndc）2（344-pytpy）（H2O）3DMF]（2,6-H2ndc= 2,6-naphthoic acid, 344-pytpy=2,6-bis（4＇-pyridyl）-4-（3＇-pyridyl）pyridine）. The single-crystal X-ray diffraction analysis shows that Cul coordinate with two oxygen atoms from two main ligands, one nitrogen atom from auxiliary ligand and two water molecules, Cu2 coordinate with two oxygen atoms from two main ligands, one nitrogen atom from auxiliary ligand, one water molecule and one DMF molecule, they are all tetrahedral configuration. The metal atoms which connect with each other according to auxiliary ligand form an interesting stair-like structure. The complex has good thermal stability.
