Synthesis and substitution reactions of dinuclear molybdenum complexes containing Mo-Mo quadruple bonds and labile solvent ligands

The kinetically labile acetonitrile ligands of [Mo 2 (O 2 C-t-Bu),(MeCN) 2 ]+(BF 4 - ) (1) have been selectively replaced by the anions derived from deprotonation of 6-hydroxy-2-methylpyridine (mhp) and 2,6-dimethylpyridine (dmp) to yield the triscarboxylate complexes Mo 2 (O 2 C-t-Bu) 3 (mhp) (3) and Mo 2 (O 2 C-t-Bu) 3 (dmp) (4), respectively
