The reaction of HB(Me2pz)3}Mo(NCS)(S4) [HB(Me2pz)3- = hydrotris(3,5-dimethylpyrazolyl)borate anion] with dicarbomethoxyacetylene in refluxing toluene results in the formation of the brown, diamagnetic complex HB9Me2pz)3}Mo(NCS)S2C2(CO2Me)2} (1) (the reactants above also yield 1 upon prolonged reaction in dichloromethane at 25-degrees-C), which has been characterized by X-ray crystallography. The mononuclear at 25-degrees-C), which has been characterized by X-ray crystallography. The mononuclear pseudo-octahedral complex contains a facially tridentate HB(Me2pz)3- ligand, a monodentate N-bound NCS- ligand, and a bidentate S2C2(CO2ME)2(2-) ligand having a near planar MoS2C4 fragment and A SC=CS bond distance of 1.342(15) angstrom. Solutions of 1 are unstable in air and decompose to produce HB(Me2pz)3}MoO2(NCS) and HB(Me2pz)3}MoO(NCS)2.
