Abstract
The mechanism proposed in the literature to account for the photolabil ization of MoV2O2(mu-O)2(H2O)mL6-mn+ for L = H2O, Cl-, and NCS- in aqu eous acid solutions is supported by extended Huckel calculations. For the single-bridged dimeric molybdenum (V) complexes containing the Mo2 O34+ core proposed as photolysis intermediates, the experimental compl exing constants of reaction (1) L- + Mo2O2(mu-O)(H2O)84+ reversible Mo 2O2(mu-O)(H2O)7L3+ + H2O (1) were found to correlate the corresponding calculated changes in electronic energy.
