Structure of bis(4-chlorophenolato)[hydrotris(3,5-dimethyl-1- pyrazolyl)borato]oxomolybdenum(V)

[Mo(C15H22BN6)(C6H4ClO)2O], M(r) = 664.24, triclinic, P1, a = 10.585 (2), b = 12.068 (3), c = 13.728 (3) A, alpha = 88.01, beta = 69.94, gamma = 65.78 degrees, V = 1490.8 A3, Z = 2, Dx = 1.48 g cm-3, Mo K alpha, lambda = 0.71073 A, mu = 6.5 cm-1, F(000) = 678, T = 296 (1) K, R = 0.034, wR = 0.049 for 4634 observed independent reflections with F2 greater than 3 sigma (F2). This is the second structurally characterized mononuclear monooxo transition-metal complex containing the phenolato ligand. The molecule exhibits a distorted octahedral coordination geometry, and the Mo atom is ligated by a terminal O atom, two p-chloro-substituted phenolato groups, and a tridentate facially coordinated hydrotris(3,5-dimethylpyrazolyl)borate ligand (L).
