    Abstract

    Reaction of the square antiprismatic cluster [ppn][Ru88-P)(μ-CO)2(CO)20] [ppn = bis(triphenylphosphoranylidene)ammonium] with triphenylphosphine proceeds by loss of one cluster core vertex, phosphine P-C cleavage, and CO insertion into the putative Ru-phenyl bond to afford [ppn][Ru77-P)(μ-η2-OCPh)(μ-PPh2)(μ-CO)(CO)17] in low yield, the first heptaruthenium μ7-phosphido-ligated cluster.
