Protolysis of the transition-metal diamides [M{N(SiMe3)2}2(thf)n] (M = Cr, Mn, Fe or Co) with 2 equivalents of phosphinochalcogenoic amides But2P(E)NHR (E = Se or Te, R = Pri or cyclo-C6H11) gave a series of thermally stable metal-selenium and -tellurium complexes [M{But2P(E)NR}2]. The complex [Ni{But2P(Se)NR}2] was obtained from Li[But2(Se)NR] and [NiCl2(PMe3)2]. The compounds sublime readily under reduced pressure and are suitable for the gas-phase deposition of metal chalcogenide films. The selenium precursors lead to MSe (M = Cr, Mn, Fe or Ni), while tellurium complexes afford MTe2 (M = Fe, Mn or Co). By contrast, [Co{But2P(Se)NR}2] gives Co3Se4, while [Ni{But2P(Se)NR}2] generates NiSe or Ni6Se5, depending on the deposition conditions.
