Thirteen molybdenum-molybdenum dimetallic and five molybdenum-halide cyclopentadienyl carbonyl compounds have been prepared from complexed hexacarbonylmolybdenum with bulkier substituted cyclopentadienyl anions which came from the reaction of 6,6-dialkylfulvenes with aryllithium. Their IR, 1H NMR, 95Mo NMR spectra have been discussed. The crystal structure of [(CH3)2C(m-CH3C6H4)C5H4]Mo(CO)3Br was determine
