Aqua-2κO-μ-{N,N′-bis[2-(dimethylamino)ethyl]oxamidato(2-)}-1κ2O,O′:2 κ4N,N′,N",N′′′-bis(4,4′-dimethyl-2,2′-bipyridine-1κ2N,N′)copper(II)nickel(II) bis (perchlorate) methanol hemisolvate

In the crystal structure of the title complex, [ CuNi( C10H20N4O2)( C12H8N2)(2)( H2O)]( ClO4) 2 center dot 0.5CH(4)O or [ CuNi( dmaeoxd)( phen)(2)( H2O)]( ClO4)(2) center dot 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.
