title: Electronic structure of cis-Mo(P)(NO)2, where P is a porphyrin: an organometallic perspective of metalloporphyrin-NO complexes.
abstract: This study presents a first MO analysis of the stereochemistry of cis-Mo(P)(NO)(2), where the Mo(NO)(2) unit eclipses a pair of opposite Mo-N bonds and also adopts a remarkable horseshoe-like conformation. In addition, we have uncovered a number of analogies--in terms of commonalities of metal-ligand orbital interactions--between the dinitrosylmetalloporphyrins, Fe(P)(NO)(2) and Mo(P)(NO)(2), and the two dialkylmetalloporphyrins, Ru(P)(CH(3))(2), and Zr(P)(CH(3))(2).
