 Title    Sulfur and Selenium Complexes of the Hydrido-tri(3,5-dimethyl-l- pyrazolyl)borate Nitrosylmolybdenum Fragment, [Tp*Mo(NO)]. An X-Ray Crystal Structure Determination of Tp*Mo(NO)(Se5)  
 Abstract    The reactions of hydrido-tri(3,5-dimethyl-l-pyrazolyl)borate nitrosylmolybdenum diiodide, Tp*Mo(NO)L (2), with the oligochalcogenides (N H ^Sio and (NEuteSeö in THF solution lead to mononuclear cvc/o-pentachalcogenido complexes, Tp*Mo(NO)(E5) (E = S (3a), Se (3b)). In the presence of either H2S or H^Se (generated by slow "in situ" hydrolysis of AI2E3 in moist THF solution) 2 is converted into binuclear chalcogenido-bridged products, Tp2Mo2(NO)2(//-E)2 (E = S (4a), Se (4b)) which are more conveniently obtained from 3a,b by dechalcogenation with tri(''butyl)phosphane (1:4,5). The new chalcogen complexes 3a,b and 4a,b were characterized by IR, NMR and mass spectroscopy and compared with the related chalcogen compounds derived from pentamethylcyclopentadienyl nitrosylmolybdenum diiodide, Cp*Mo(NO)l2. The molecular structure of Tp*Mo(NO)(Ses) (3b) has been determined; the complex contains a six-membered MoSe«; metallacycle in the chair conformation and a linearly coordinated nitrosyl ligand (angle M o -N -0 178.9(17)°).
