Sulphur inversion in dimolybdenum complexes: X-ray crystal structure of [Mo2(CO)2{P(OMe)3}(µ2-SBut)3(η7-C7H7)]
Abstract
Low energy barriers are observed for sulphur inversion in complexes [Mo2(CO)2(L)(µ2-SR)3(η7-C7H7)](R = Me, Et, Pri, or But); n.m.r. spectroscopy reveals complete averaging of R group environments when L = CO but only a limited averaging when L = PR′3, a situation clarified by an X-ray diffraction study of [Mo2(CO)2{P(OMe)3}(µ2-SBut)3(η7-C7H7)].
