Abstract

New complexes [Cr(CO) ₄ (R ₂ P(S)P(S)R ₂ )] and [Cr ₂ (CO) ₁₀ (μ-R ₂ P(S)P(S)R ₂ )] (R = Me, Et, Pr ⁿ , Bu ⁿ ), (1a)-(1d) and (2a)-(2d) [(1a), R = Me; (1b), R = Et; (1c), R = Pr ⁿ ; (1d), R = Bu ⁿ ; (2a), R = Me; (2b), R = Et; (2c), R = Pr ⁿ ; (2d), R = Bu ⁿ ] have been prepared by the photochemical reaction of Cr(CO) ₆ with R ₂ P(S)P(S)R ₂ (R = Me, Et, Pr ⁿ and Bu ⁿ ) and characterized by elemental analyses, FT-i.r., ³¹ P-[ ¹ H]-n.m.r. spectroscopy and FAB-mass spectrometry. The spectroscopic data suggest cis-chelate bidentate coordination of the ligand in [Cr(CO) ₄ (R ₂ P(S)P(S)R ₂ )] and cis-bridging bidentate coordination of the ligand between two metals in [Cr ₂ (CO) ₁₀ (μ-R ₂ P(S)P(S)R ₂ )] (R = Me, Et, Pr ⁿ and Bu ⁿ ).
