An Oxalato-Bridged Cu(II)-Based 1D Polymer Chain: Synthesis, Structure, and Adsorption of Organic Dyes.

In the current research, we prepared a polymeric framework, {[Cu(CO)(CHN)]·HO·0.67(CHOH)]} () (where CO = oxalic acid; CHN = 2,2-bipyridine), and explored this compound for adsorption of methylene blue (MB) and methyl orange (MO). The crystal structure of the compound consists of a Cu(ox)(bpy) unit connected via oxalate to form a 1D polymeric chain.
