Mononuclear Compounds - Gmelin Handbook of Inorganic and Organometallic Chemistry - 8th edition / Mo. Molybdän. Molybdenum System-Nr. 53 - Part 7 Author:Hans Schumann This volume continues the description of mononuclear cyclopentadienyl molybdenum compounds and their derivatives, 5LMo. It describes 5LMo compounds containing two CO groups, but no additional nL ligands. nL are denoted in these series as organic ligands bonded by n C atoms to the Mo atom. Derivatives include ligands X (e.g. halogens anions such ... more »as OSO2R, etc.) or mD (e.g. PR3, P(OR)3, ethers, thioethers, etc). mD are electron donor ligands, where m gives the number of donor electrons. Ionic compounds of this type with ÄC5H5Mo(Co)3Ü- as counter anion are also described.« less
