We report the syntheses and IR spectra of phosphanciminato complexes of molybdenum: (Mo V Cl 4 (NPPh 3 )(PPh 3 )] (I) PPh 4 [MoIVCl 4 (NPPh 3 )(PPh 3 )] · 2CCl 4 (II) PPh 4 [MoVCl 5 (NPCl 3 )] (III) I is obtained from [MoNCl 4 ] 2 and triphenylphosphane, or from [MoCl 4 (NSCl)] 2 and triphenylphosphane: II was prepared by reacting MoNCl 4 with triphenylphosphane followed by treatment with tetraphenylphosphonium chloride; III can be generated from PPh 4 [MoNCl 4 ] with PCl 3 /PCl 5 . Complex I is paramagnetic (μeff, = 1.83 B.M., d 1 -configuration): II is diamagnetic (d 2 -system).
