Facile synthesis of heterotrimetallic metal-string complex [NiCoRh(dpa)4Cl2] through direct metal replacement

This communication provides a practical strategy for the synthesis of heterotrimetallic extended metal atom chains with supported dpa(-) ligands. The transformation of the CoCoRh to a NiCoRh trinuclear complex can be achieved by direct metallic replacement. Furthermore, the first (CoRh)(4+) metal-metal bond is described here.
