Abstract

Mild reduction with metals: Elemental gallium is used as mild reducing agent for transition-metal halides to generate subvalent GaCl ligands in novel clusters. In the reaction of Ga with [{CpRhCl2}] (Cp=5-1,3-C5H3tBu2), clusters with GaCl ligands and with unprecedented two-coordinate Ga centers in a multicenter-multiple-bonding interaction between two rhodium centers are formed (see picture).
