Özet

New complexes [Cr(CO)(4) (R2P(S)P(S)R-2)] and [Cr-2(CO)(10)(mu-R2P(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 (RP)-P-2(S)P(S)R-2 (R=Me, Et, Pr-n and Bu-n) and characterized by elemental analyses, FT-i.r., P-31-[H-1]-n.m.r. spectroscopy and FAB-mass spectrometry. The spectroscopic data suggest cis-chelate bidentate coordination of the ligand in [Cr(CO)(4)(R2P(S)P(S)R-2)] and cis-bridging bidentate coordination of the ligand between two metals in [Cr-2(CO)(10)(mu-R2P(S)P(S)R-2)] (R=Me, Et, Pr-n and Bu-n).
