The first heptaruthenium cluster: X-ray crystal structure of Ru7(CO)18(µ4-PPh)2, a molecule consisting of fused square pyramidal polyhedra
Abstract
The first heptaruthenium cluster Ru7(CO)18(µ4-PPh)2 has been obtained from the pyrolysis of the phosphido complex (µ-H)Ru3(CO)10(µ-PPh2) in toluene; X-ray analysis has revealed a novel condensed metal framework based on two square pyramidal Ru5 fragments sharing a common face.
