Abstract
The first two cobaltacarboranes with intramolecular phoshorus bridges and two related non-bridged trimethylphosphine-cobaltacarborane deriva tives are described and characterized by mass spectrometry and multinu clear NMR; all foul compounds are zwitterions: 8,8'-mu-Me2P(1,2-C2B9H1 0)(2)-3-Co (1a), 6,6'-mu-Me2P(1,7-C2B9H10)(2)-2-Co (2a), (8-Me3P-1,2-C 2B9H10)-3-Co-(1,2-C2B9H11) (1b) and (6-Me3P-1,7-C2B9H10)-2-Co-(1,7-C2B 9H11) (2b). X-Ray structures of the first two and of the last compound has been established.
