Tricarbon-yl(η-flavone)chromium(0).

In the title compound, [Cr(C(15)H(10)O(2))(CO)(3)], the Cr(CO)(3) unit exhibits a three-legged piano-stool conformation. The chromium metal centre is coordinated by the phenyl ring of the flavone ligand [Cr-(phenyl centroid) distance = 1.709 (1) Å]. The ligand is approximately planar, the dihedral angles between the γ-pyrone ring and the phenyl ring and between the γ-pyrone and the phenyl-ene ring being 2.91 (5) and 3.90 (5)°, respectively. The mol-ecular packing shows π-π stacking between the flavone ligands of neighbouring mol-ecules.
