ABSTRACT
In the title compound, [Cr(C(16)H(16)O(2))(CO)(3)], the Cr(0) atom of the Cr(CO)(3) unit is coordinated to the phenyl ring of the flavan ligand in an η(6) mode, with a normal arene-to-metal distance. The Cr(CO)(3) unit exhibits a three-legged piano-stool conformation, while the dihydro-pyran ring displays a distorted envelope configuration. The phenyl ring is twisted away from the fused ring system by 25.5â
(2)°. The meth-oxy group is almost coplanar with the phenyl ring [C(Me)-O-C(ar)-C(ar) torsion angle = 8.46â
(2)°]. The crystal packing is stabilized by inter-molecular C-Hâ¯O inter-actions.
