W(CO)5OPH(CR(CO)3)-, AND ITS REACTIVITY WITH CARBON-DIOXIDE AND CARBONYL SULFIDE THE SYNTHESIS AND X-RAY STRUCTURE OF A PHENOXIDE-BRIDGED HETEROBIMETALLIC ANION

The heterobimetallic complex, [Et4N][W(CO)5OPh(Cr(CO)3)] (1), was prepared by the reaction of [Et4N][W(CO)5CH3] and (6C6H5OH)Cr(CO)3 in tetrahydrofuran. Complex 1 crystallizes from THF/hexane in the space group P21 with unit cell dimensions a = 7.036(2) , b = 11.766(4) , c = 15.460(4) , = 94.83(2), V= 1275.3(7) 3, and Dcalcd = 1.779 g cm-3 . The structure was refined to R = 0.084 and Rw = 0.091 for 1136 reflections having F > 3.0(Fo). Complex 1 was completely inert towards carbon dioxide, even at high pressure (900 psi), but readily reacted with carbonyl sulfide to afford the thiocarbonate derivative, [Et4N][W(CO)5SC(O)OPh(Cr(CO)3)]. 1993.
