Abstract
The crystal and molecular structure of tetrakis(mu -o-propionato)bis(methyl 3-pyridyl-N-carbamate)dicopper(II) at 190 K was determined by X-ray analys is. The internuclear Cu . . . Cu distance is 2.6395(3) Angstrom. Cu-O bond lengths are 1.961(1). 1.9678(9), 1.9828(9) and 1.9979(9) Angstrom and Cu-N bond length is 2.165(1) Angstrom. The non-bonding Cu(II). . . Cu(II) contac ts for nine binuclear Cu(II) propionates and hexacoordination of Cu(II) ion in the structure of [Cu(CH3CH2COO)(2)(mpc)(2)]0.25H(2)O (mpc = methyl 3-py ridyl-N-carbamate) is consistent with the bond-valence sum model.
