SYNTHESIS OF A DINUCLEAR, PHOSPHIDO-BRIDGED COMPLEX OF RHENIUM, X-RAYCRYSTAL-STRUCTURE OF RE-2(MU-H)[MU-(T-BU)PC6H4P(H)T-BU](CO)(7)

The thermal reaction of Re-2(CO)(10) and 1,2-[t-BuPH](2)C6H4 in xylene gives Re-2(mu-H)[mu-(t-BuP)C6H4(t-BuPH)] (CO)(7) (1) in 70% yield. Th e crystal structure of 1 has been determined. Compound 1 crystallized in the monoclinic space group P2(1)/n with Z = 4; a = 10.953(3), b = 1 3.271(4), c = 17.969(7) Angstrom; beta = 104.48(2)degrees. The final R and R-w were 0.037 and 0.036, respectively. (C) 1998 Elsevier Science S.A. All rights reserved.
