mu-[3,10-Dimethyl-4,9-diaza-3,9-dodecadiene-2,11-dione dioximato(1-)-mu-O,N,N',N",N"']-nickel(II) perchlorate, [Ni(C12H21N4O2)]+.ClO4-, M(r) = 411.5, triclinic, P1BAR, a = 6.533 (2), b = 10.840 (3), c = 12.979 angstrom, alpha = 103.57 (3), beta = 95.76 (3), gamma = 103.16 (2)-degrees, V = 858.5 (5) angstrom 3, Z = 2, D(x) = 1.592 Mg m-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 1.33 mm-1, F(000) = 428, R = 0.0440, wR = 0.0494 for 2417 independent reflections at 296 K. An oxime proton is lost from the ligand in forming the complex and the remaining oxime proton forms an intramolecular hydrogen bond between the two oxime oxygens. The Ni(II) atom is in a distorted square planar coordination. The average values for the important bond distances are Ni-N(oxime) = 1.871, Ni-N(imine) = 1.907, O...O = 2.443 angstrom for the intramolecular hydrogen bond.
