| Tris(glykolato)molybdän(VI) und T ris(pinakolato)molvbdän(VI) Syntheses and C rystal Structures o f T ris(glycolato)m olybdenum (V I) and T ris(pinacolato)m olybdenum (V I) Silke B uth, Sigrid W ocadlo, B ernhard N eum üller, F ra n k W eller und K u rt Dehnicke* PPh4[M oN (O Ph)4] has been prepared by reaction o f PPh4[M oN C l4] with sodium phenolate, as an orange-red crystal powder. The reactions o f glycole and pinacole, respectively, with M oN (0-r-B u)3 and M oN C 13, the latter in the presence o f a base, lead to the /rä-chelate com plexes M o(O C 2H40) 3 and M o(OC:M e40) 3, respectively. The complexes were characterized by 'H and l3C N M R spectroscopy, the chelate complexes in addition by X-ray structure analysis. [Mo(OC-,H40) 3]: Space group P 2,/c, Z = 4, 2177 observed unique reflections. R = 0.047. Lattice dim ensions at -4 0 °C: a = 1168.3(2), b = 716.0(1), c = 1206.1(2) pm, ß = 92.84(1)°. [M o(OC2Me40) 3] • 2 C H 2C12: Space group Pbcn, Z = 4, 1860 observed unique reflections, R = 0.049. Lattice dimensions at -8 0 °C: a = 1772.3(1), b = 1023.8(1), c = 1600.0(2) pm. Both complexes form monomeric molecules, in which the molybdenum atom s are surround ed in a distorted octahedral fashion by the six oxygen atom s o f the chelates. | | | |
