Synthesis and characterization of bis-triruthenium cluster derivatives of an all equatorial [60]fullerene tetramalonate†
Abstract
The reaction of the tetrakis[di(ethoxycarbonyl)methano]-C60 (1) with Ru3(CO)12 afforded the first bis-parallel C60–metal cluster complex: parallel-[Ru3(CO)9]2{μ3-η2,η2,η2-C60[C(COOC2H5)2]4}. The two triruthenium groups are found in either a parallel or a tilted orientation relative to each other, as determined by NMR. Only the parallel form was characterized by X-ray crystallography.
