1,3-Diphosphacyclobutadiene sandwich compounds as bidentate ligands in metal carbonyl chemistry: Binuclear chromium derivatives

The only low-energy Me2C2P2)2Cr2(CO)6 structure consists of a bidentate (η4-Me2C2P2)2Cr(CO)2 sandwich diphosphine ligand bonded to a Cr(CO)4 unit with a long Cr⋯Cr distance. Bridging η1,4-Me2C2P2 ligands are found in the low-energy singlet (Me2C2P2)2Cr2(CO)5 structures whereas the lowest energy (Me2...
