Figure 1. Titration plot for the reduction of MoO, detc, by H4dmp. The reaction progress was monitored with the strong absorption band of MoO (detc), at 505 nm. Titration of MoO,(detc), by H4dmp was performed in a 50% CH2C12/50% CH, OH solvent mixture. A constant total molybdenum concentration of 0.107 m M was maintained for all samples, and, at this concentration, the dimer Mo, O,(detc), represents less than 1.5% of the total molybdenum ...
