[[abstract]][3,3'-(2,2-Dimethyl-1,3-propanediyldinitrilo)di(2-butanone oximato)(1-)-N,N',N'',N'''] nickel perchlorate, [Ni(C13H23N4O2)](ClO4), M(r) = 425.5, monoclinic, P2(1)/c, a = 7.161 (3), b = 18.945 (3), c = 13.949 (4) angstrom, beta = 103.47 (1)degrees, V = 1840.2 (9) angstrom3, Z = 4, D(x) = 1.536 Mg m-3, lambda(Mo Kalpha) = 0.7093 angstrom, mu = 1.24 mm-1, F(000) = 887.81, T = 298 (4) K, R = 0.039, wR = 0.040, for 2729 significant reflections. The coordination about Ni(II) is slightly distorted square planar. The Ni(II) ion is a little (0.056 angstrom) out of the square coordination plane, towards the perchlorate ion. There are intramolecular and intermolecular hydrogen bonds between O atoms.
