Tricarbonyl[(6a,7,8,9,10a-eta)-3,3-dimethyl-3H-benzo[f]chromene]chromium.
The title compound, [Cr(C(15)H(14)O)(CO)(3)], is a chromene complexed with tricarbonylchromium and it exhibits photochromic properties. The molecular geometry is compared to that of two similar complexes. The analysis results indicate that complexation has minor effects on the chromene structure.
