Abstract

The title compound, [Cr(C15H14O)(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.
