Abstract: The title complex of a deprotonated form of morpholine biguanide with CuII, 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.
