Özet

The complexes fac-[Re(CO)(3)Br{Ph2P(S)(CH2)(n)P(S)Ph-2}] [1a, n = 1; 2a, n = 2; 3a, n = 3] and [Re-2(CO)(8)Br-2{mu-Ph2P(S)(CH2)(n)P(S)Ph-2}] [1b, n = 1; 2b, n = 2; 3b, n = 3] have been prepared by the photochemical reaction of Re(CO)(5)Br with Ph2P(S)(CH2)(n)P(S)Ph-2. The products have been characterized by elemental analysis, mass spectroscopy, FT-IR and P-31-[H-1]-NMR spectrometry. The results suggest cis-chelate bidentate coordination of the ligand in fac-1a-3a and cis-bridging bidentate coordination of the ligand between two metals in 1b - 3b.
