| Abstract: | Bis(triphenylphosphine)(η-cyclohexa-1,3-diene)rhenium trihydride, (Ph3P)2(η-C6H8)ReH3 (I) crystallises in the space group C2/c with cell dimensions a 22.76(2), b 10.14(1) c 29.813(6) Å, β 97.69(8)°. The final refinement of 126 variables using 1580 non-zero reflections resulted in a final R value of 0.064. In spite of uncertainties in some of the atomic positions, the structure of I is compatible with a trihydrido diene compound with a distorted pentagonal bipyramidal configuration, rather than with a dihydrido cyclohexenyl compound having an “agostic” CH ? Re interaction. The factors which govern the structure of the complexes (Ph3P)2(η-1,3-diene)ReH3 are discussed. |
