Bis{N'-[(E)-amino(imino)methyl]morpholinocarboximidamido}copper(II)

L. P. Lu and M. L. Zhu

Abstract: The title complex of a deprotonated form of morpholine biguanide with Cu^II, namely bis(2-morpholinobiguanido)copper(II), [Cu(C₆H₁₂N₅O)₂], was characterized crystallographically. The Cu²⁺ ion, on a centre of symmetry, is coordinated by four N atoms from two bidentate morpholine biguanide monoanions; the biguanide groups of the two ligands and the copper ion are coplanar. The two morpholine rings of the ligands are in a trans configuration and have a chair conformation.
