Synthesis and X-ray crystal structure of the cluster dianion, [Rh10(CO)21]2–, containing a new compact array of metal atoms
Abstract
The anion [Rh10(CO)21]2–, obtained by reaction of [Rh9(CO)19]3– with the [Rh(CO)2(NCMe)2]+ cation, contains a novel decanuclear metallic skeleton which is a fragment of hexagonal close-packed lattice formed by three superimposed layers (3/4/3 metals), with two octahedral and two tetrahedral condensed units as confirmed by X-ray crystallography.
