Abstract

The complexes [MoO(SR)4]- (R = aryl) and [MoO{S(CH2)nS}2]- (n = 2 or 3) can be prepared by reaction of an MoVI butanediolato-complex with thiolate anion in methanol. The complexes [MoO(SPh)4]- react with R′2NNH2 [R′2 = Me2 or (CH2)5] in refluxing CH3CN to give [Mo(NNR′2)O(SPh)3]-. Crystal Data for [PPh4] [Mo(NNMe2)O(SC6H5)3]·(C 2H5)2O: space group Pbca, a = 12.789(4), b = 19.375(3), c = 36.941(3) Å, Z = 8.3 225 Independent reflections with I > 3σ(I) gave R = 0.076. The geometry is essentially square-pyramidal with an apical oxo-group and the NNMe2 group in the basal plane. Although the MO-N and N-N distances of 1.821(9) and 1.292(14) Å respectively are analogous to other hydrazido(2-) complexes, the Mo-N-NMe2 system is anomalously bent with MO-N-N = 152.5(10)°.
