摘要
A novel copper complex polymer {[Cu-4(dmg)(2)(Hdmg)(2)(H(2)dmg)(2)(H2O)(2)](ClO4)(2)}(infinity) (H(2)dmg = dimethylglyoxime) has been synthesized and its structure was determined by X-ray single crystal diffraction methods. The complex polymer is like a ID infinite chain with topological type as a sequence of fused rings connected by out-planar Cu-O bonds, in which oximato groups (=N-O-) act as two-dentate bridges to link center Cu2+ cations. This structure shows that oximes have great perspective in coordination chemistry and supramolecular polymer chemistry. Molecular structure and spectroscopic properties of the polymer complex were discussed in the article. (C) 2002 Published by Elsevier Science B.V.
