摘要：
The structure of bis(N1,N1-dimethylbiguanide-N2,N4)copper(II) bis(hydrogencarbonate) consists of a [Cu(C4H11N5)2]+ cation and two HCO3- anions. The Cu atom is at a centre of symmetry and forms a square-planar structure with four N atoms belonging to two N,N-dimethylbiguanide (metformin) groups. The metformin ligand is planar, allowing delocalization of the pi electrons in the metal-ligand ring. The hydrogencarbonate anions are hydrogen bonded to N(1), N(2) and N(3).
