Crystal structure of a new oximato-bridged one-dimension(1D) chain-like copper complex polymer {[Cu_4(dmg)_2(Hdmg)_2(H_2dmg)_2(H_2O)_2](ClO_4)_2}_infinity

摘要

A novel copper complex polymer {[Cu_4(dmg)_2(Hdmg)_2(H_2dmg)_2(H_2O)_2](ClO_4)_2}_infinity (H_2dmg=dimethylglyoxime) has been synthesized and its structure was determined by X-ray single crystal diffraction methods. The complex polymer is like a 1D 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 Cu~(2+) 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.
