Abstract
The interaction of Mo(η5-C5H5)2(MeCN) with HBF4·Et2O in MeCN gives the molybdenum(IV) complex [Mo(η5-C5H5)2(MeCN)(NHCHMe)][BF4]2(2) which on substitution with PMe3 gives [Mo(η5-C5H5)2(PMe3)2][BF4]2(3). Similar protonation of Mo(CO)3(MeCN)3 under hydrogen gives the complex [Mo(CO)2(MeCN)3(η3-CH2CHNH2)]BF4(4) and in the presence of oxygen the molybdenum(III) complex [Mo2(µ-O)(MeCN)10][BF4]4(5). X-Ray crystal structures of compounds (2), (3), (4), and (5) are reported.
