N2 - 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 ).
