The volume is quite topical: even information published in 1994 is here. The first 36 pages devoted to binuclear organorhenium compounds cover compounds bearing only rhenium-bonded alkyl or aryl ligands. The concluding 426 pages treat binuclear compounds having from one to ten rhenium-bonded CO groups, other than Rh2(CO)10 itself; the compounds may contain additional X, D, alkyl, or aryl ligands. Indexes, including cross references from other transition metals in the ligands, make access to the 1100 compounds decribed here - and their properties - quick and easy.
