    • Abstract


      The unsymmetrical diphosphazanes X2PN(Pri)PYY′(1a1h) {X=Ph, YY′=O2 C6H4 (1a) or YY′=O2C12H8 (1b); X=Ph, Y=Ph, Y′=OC6H4Me-4 (1c), OC6H4Br-4 (1d), OC6H3Me2-3,5 (1e), OC5H4N-2 (1f), N2C3HMe2-3,5 (1g) or Cl (1h)} react with [M(CO)4(NHC5H10)2] (M=Mo, W) to yield thecis-chelate complexes [M(CO)4{X2PN(Pri) PYY′}] {M=Mo (2a2h); M=W (3f,3g)}. These complexes have been characterized by1H,31P and13C NMR and IR spectroscopic studies.
