Bi-edge condensation of imido–rhodium clusters leading to novel planar hexametallic structures
Abstract
Oxidation of [N(PPh3)2][Rh3(µ-NC6H4Me-p)2(CO)6] with [FeCp2]PF6 gives the novel hexarhodium compound [{Rh3(µ-NC6H4Me-p)2(CO)6}2], containing three nearly coplanar condensed metallic cycles forming a doubly-spiked square, by dimersisation of the trinuclear imidocomplex through the formation of unsupported metal–metal bonds.
