摘要

A novel discrete dinuclear metallacyclic copper(Ⅱ) complex, [Cu2L2(H2O)2]·3H2O (1) has been firstly prepared where L is derived from the 1: 2 condensation of 2,2'-bipyridyl-3,3'-diformylhydrazide and acetone during the formation of the complex. Single-crystal X-ray diffraction analysis determines that the complex consists of dinuclear metallacyclic units [Cu2L2(H2O)2] where two metal centers are linked together through two bis(chelating)bridge ligands L to form a bizarre cavity with size 0.9417 nm×0.4999 nm×0.6930 nm. Interestingly, the metal coordination also creates hydrogen bond sites that further aggregate these metallacycles into a 3D supramolecular structure with 2D perpendicular hydrophilic tunnels in crystal.
