A molybdenum complex with 4,7-diphenyl-1,10-phenanthroline

In the title compound, tetracarbonyl(4,7-diphenyl-1,10-phenanthroline-N,N′)molybdenum(0), [Mo(C24H16N2)(CO)4], the Mo-atom coordination is distorted octahedral, with two CO groups cis to each other, but each trans to an N atom of the 4,7-diphenyl-1,10-phenanthroline (dpphen) ligand, and with the other two CO groups trans to each other and on the axis position. The complex has better solubility than [Mo(phen)(CO)4], where phen is 1,10-phenanthroline.

Mechanism of chelation of phenanthroline derivatives to Mo(CO)5 deduced from pulsed photolysis studies in several solvents at high pressure

A laser flash-photolysis kinetic study has been carried out on the concentration, temperature and pressure dependence of chelation reactions of the type +CO, where L-L represents 1,10-phenanthroline (phen) and a series of substituted phen ligands in several solvents.The activation parameters for these thermal ring-closure reactions are sensitive to the nature of the solvent, as well as to electronic and steric effects arising from the phen ligand.All the observed kinetic effects can be accounted for by an interchange ligand-substitution mechanism during which CO is displaced by the chelate.
