STRUCTURE OF BIS(4-BENZOYL-2,4-DIHYDRO-5-METHYL-2-PHENYL-3H-PYRAZOL-3-ONATO-O,O')DINITRATOBIS(TRIPHENYLPHOSPHINE OXIDE-O)THORIUM(IV)

[Th(C17H13N2O2)2(NO3)2(C18H15OP)2], M(r) = 1467, orthorhombic, Pcan, a = 11.619 (10), b = 23.721 (10), c = 25.243 (4) angstrom, V = 6957.33 angstrom 3, Z = 4 D(x) = 1.40 g cm-3, lambda-(Mo K-alpha) = 0.71069 angstrom, mu = 23.2 cm-1, F(000) = 2936, T = 298 K, R = 0.058 for 2547 reflections with I greater-than-or-equal-to 2-sigma-(I). The crystal is composed of discrete molecules containing a thorium ion coordinated to ten O atoms from two bidentate benzoyl pyrazolone anions, two bidentate nitrate anions, and two triphenylphosphine oxide molecules.
