A copper–polyol complex: Na2(C2H6O2)6Cu(C2H4O2)2

摘要

The ionic title complex, bis(μ-ethyl­ene glycol)-κ³ O,O′:O′;κ³ O:O,O′-bis[(ethyl­ene glycol-κ² O,O′)(ethyl­ene glycol-κO)sodium] bis(ethyl­ene glycolato-κ² O,O′)copper(II), [Na2(C2H6O2)6][Cu(C2H4O2)2], was obtained from a basic solution of CuCl2 in ethyl­ene glycol and consists of discrete ions inter­connected by O—H⋯O hydrogen bonds. This is the first example of a disodium–ethyl­ene glycol complex cation cluster. The cation lies about an inversion center and the Cu^II atom of the anion lies on another independent inversion center.
