PI-ARENE CLUSTERS OF COBALT AND RUTHENIUM ON THE BASE OF BIPHENYL

For the first time monocluster pi-arene derivatives of biphenyl Ph2Co4 (CO)9 and Ph2Ru6C(CO)14, the shared mononuclear monocluster complex Ph 2Cr(CO)3Co4(CO)9, and the bicluster derivative of cobalt Ph2[Co4(CO)9] 2 have been synthesized. IR and H-1 NMR spectra of the compounds have been studied.
