Determination of the structure of tetracarbonylnitrosylmanganese by matrix isolation studies

Abstract

Matrix isolation studies, including ¹³CO enrichment, have demonstrated that the i.r. spectrum of [Mn(CO)₄NO] is consistent with C_2v symmetry (trigonal bipyramid with equatorial NO ligand) in accordance with X-ray crystallographic studies; the work resolves the disparity between previous solution i.r. studies (C_3v) and X-ray studies (C_2v).
