Abstract

The new complexes fac-[Re(CO)₃Br{Ph₂P(CH ₂)_nPPh₂}] (1a-3a) [(1a), n = 1; (2a), n = 2; (3a), n = 3] and [Re₂(CO)₈Br₂{μ-Ph ₂P(CH₂)_nPPh₂}] (1b-3b) [(1b), n= 1; (2b), n = 2; (3b), n = 3] have been prepared by the photochemical reaction of Re(CO)₅Br with Ph₂P(CH₂)_nPPh ₂ (n = 1, dppm; 2, dppe; 3, dppp). The complexes have been characterized by elemental analysis, mass spectroscopy, f.t.-i.r. and ³¹P-[¹H]-n.m.r. spectrometry, The spectroscopic studies suggest cis-chelate bidentate coordination of the ligand in fac-[Re(CO) ₃Br{Ph₂P(CH₂)_n PPh₂}] (1a-3a) and cis-bridging bidentate coordination of the ligand between two metals in [Re₂(CO)₈Br₂{cis-μPh ₂P(CH₂)_nPPh₂}] (1a-3a).
