A high-yield synthesis of Ru5C(CO)15 by the carbonylation of Ru6C(CO)17; the X-ray structure analyses of Ru5C(CO)15 and Ru5C(CO)14PPh3

Abstract

In reaction with CO at 70 °C and 80 atm the hexanuclear cluster Ru₆C(CO)₁₇ undergoes carbonylation, ejects Ru(CO)₅ and gives quantitative amounts of Ru₅C(CO)₁₅ which X-ray analysis has confirmed has a square-pyramidal Ru₅ arrangement with an exposed carbido-atom; some reactions of this pentanuclear cluster are reported together with the X-ray structure analysis of its derivative Ru₅C(CO)₁₄PPh₃.
