A series of complexes of the form TpMo(NO)(L)(
2-L
) were synthesized, where Tp =hydridotris(pyrazolyl)borate, L = 1-methylimidazole or ammonia, and L is an alkene, alkyne,ketone, polyaromatic hydrocarbon, or aromatic heterocycle. The thermal stability of thedihapto-coordinated aromatic complexes is indicative of a strong back-bonding interactionsimilar to that found in the heavy metal analogues [Os(NH3)5(2-arene)]2+, TpRe(CO)(L)(2-arene), and TpW(NO)(L)(2-arene). Several synthetic routes to these molybdenumcomplexes are outlined.
