N2  - Reaction of MoO (S2PPri2)2 and K{H2B(Me2C3N2H)2} in refluxing toluene produces green, diamagnetic, air-stable {H2B(Me2C3N2H)2}MoIVO(S2Ppri2)(1), which has been characterized by analytical, mass spectrometric, infrared and n.m.r. spectroscopic, and X-ray crystallographic techniques. Crystals of (1) are triclinic and belong to space group P&#299; , with a 10.289(1), b 13.601(2), c 8.737(1) &#506;, &#945; 94.31(1), &#946; 107.71(1), &#947; 79.56(1)&#176;, V 1145.2 &#506;3 and Z 2. The structure was solved by Patterson and Fourier methods and refined by using 3631 reflections to a final R value of 0.024 ( Rw 0.041). The five-coordinate square pyramidal complex is composed of apical terminal oxo [Mo-O(1) 1.658(2)&#506;] and bidentate H2B(Me2C3N2H)2- and S2PPri2- ligands coordinated to molybdenum. Ferrocenium oxidation of (1) produces the mononuclear molybdenum(V) complex [{H2B(Me2C3N2H)2}MoVO(S2Ppri2)]+ ( e.p.r .: g 1.964, a(95,97Mo) 41.7&#215;10-4cm-1, a(31P) 30.1&#215;10-4 cm-1).
