Oxidation of - by a molar equivalent of PPh2Cl at ca. -70 deg C yielded three dinuclear complexes, Re2(μ-Cl)(μ-PPh2)(CO)8 (1), Re2(CO)9(PPh2H) (2) and Re2(μ-H)(μ-PPh2)(CO)8 (3), as major products.When PPh2Cl was present in two-fold exc

The monoacetonitrile complex , obtained from the reaction of with freshly prepared iodosobenzene in acetonitrile solutions, reacts with the secondary phosphines PR2H in refluxing hexane to give the complexes (5a, R = Ph; 5b, R = Pr).Complexes 5, when heated to > 170 deg C in decalin, lose CO and are converted cleanly to (6a, R = Ph; 6b, R = Pr) while they react with to give (7a, R = Ph; 7b, R = Pr), complexes containing a triangular PtRe2 array withPt(μ-PR2)Re, Pt(μ-H)Re and Re-Re edges.Similarly, reaction of complexes 5 with > gives > 8 containing Pt(μ-CO)Re, Pt(μ-H)Re and Re(μPR2)Re edges.The trimetallic complex 8 slowly disproportionates to give 6 and 1/3 3>.The reaction of 6a (μ-PPh2) with > gives the complex > 7c in which the μ-PPh2 ligand has migrated from a ReRe edge in 6a to a PtRe edge in 7.Further reaction of 7c with a second equivalent of > yields the tetrametallic complex 2> 10 (μ-PPh2, μ-H and 2μ-CO on Pt-Re edges).Reaction of with > gives > and 2> 12 (4μ-CO on PtRe edges).The molecular structures of 7 b, 10 and 12 have been determined by single-crystal X-ray diffraction studies.Crystal data as follows: 7b, orthorombic, space group Pbca, a = 14.951(2), b = 18.330(2), c = 25.715(2) Angstroem, Z = 8, R = 0.0521 (R' = 0.0597) for 3700 data with I >= 3?(I); 10, monoclinic space group, P21/n, a = 15.215(9), b = 19.633(9), c = 19.446(8) Angstroem, β = 92.90(4) deg, Z = 4, R = 0.0950 (R' = 0.1006) for 6068 data with I >= 3?(I); and 12, triclinic (paramonoclinic) space group, P1/, a = 11.567(4), b = 15.308(6), c = 16.178(6) Angstroem, α = 89.87(3), β = 108.13(3), γ = 90.28(3) deg, Z = 2, R = 0.0659 (R' = 0.0716) for 7166 data with I >= 3?(I).
