Racemic tricarbonyl[(4a,5,6,7,8,8a-η)-2-phenyl-3,4-dihydro-2H-1-benzopyran]chromium(0)

Abstract

The title compound, [Cr(C15H14O)(CO)3], displays a distorted envelope configuration of the dihydropyrane ring. The dihedral angle between the phenyl and phenylene rings is 50.63 (4)°. The Cr0 atom is coordinated by three CO groups and the phenylene ring of the flavan ligand in an η6 mode, with a common arene-to-metal distance
