title: Aqua-2kappaO-mu-{N,N'-bis[2-(dimethylamino)ethyl]oxamidato(2-)}-1kappa(2)O,O':2kappa(4)N,N',N'',N'''-bis(4,4'-dimethyl-2,2'-bipyridine-1kappa(2)N,N')copper(II)nickel(II) bis(perchlorate) methanol hemisolvate.
abstract: In the crystal structure of the title complex, [CuNi(C(10)H(20)N(4)O(2))(C(12)H(8)N(2))(2)(H(2)O)](ClO(4))(2).0.5CH(4)O or [CuNi(dmaeoxd)(phen)(2)(H(2)O)](ClO(4))(2).0.5CH(3)OH {H(2)dmaeoxd is N,N'-bis[2-(dimethylamino)ethyl]oxamide and phen is 1,10-phenanthroline}, the deprotonated dmaeoxd(2-) ligand is in a cis conformation and bridges the Cu(II) and Ni(II) atoms. The Cu(II) atom is located in a slightly distorted square-based pyramidal environment, while the Ni(II) atom is in an irregular octahedral environment. The binuclear Cu-Ni units interact with each other via pi-pi interactions, which results in an extended chain along the b axis.
