BIS-[2-(2-METHYL-3-BUTANONE OXIME)] HYDRAZINE

C10H22N4O2, Mr = 230.31, triclinic, P1BAR, a = 12.010(5), b = 13.188(9), c = 9.163(2)angstrom, alpha = 107.30(4), beta = 108.35(3), gamma = 77.42(2)-degrees, V = 1303.(1) angstrom3, Z = 4, D(x) = 1. 174(2) g cm-3, (MoKalpha) = 0.71073 angstrom, mu = 0.78 cm-1, F(000) = 504, T = 297 K, R = 0.039, R(w) = 0.054 for 3023 observed reflections (of 4521 unique data). The hard, transparent, colorless crystals give sharp, intense diffraction peaks; this may be related to the strong three dimensional hydrogen bonding involving the oxime groups as well as the hydrazine hydrogens. Bond distances and angles as well as torsion angles are in good agreement for the two independent molecules and are normal. Although there is near two-fold symmetry relating the two molecules, positions of neighboring groups removes a twofold crystallographic axis.
