    Abstract:
    Proton NMR studies of (4-chromanone)chromium tricarbonyl indicate that, in solution, this compound occurs with the heterocyclic ring in a sofa conformation with an O(1)-C(2)-C(3)-C(4) torsion angle of 53°. Single-crystal X-ray analysis of the same molecule reveals that a sofa form (55.6° torsion angle) is also adopted in the solid state with the further specification that C(2) is the out-of-plane atom and is displaced in the direction proximal to the Cr(CO)3 moiety. © 1984.
