Popis:	Two further polymorphic forms (α = P2 1 and γ = P2 1 /c) of the title compound (C 21 H 17 ClO 4 ) have been obtained and their crystal structures determined. The molecular geometries and photochemical behaviour are very similar to those of the previously described β-form reported in the P2 1 /c space group [Chen, Pokkuluri, Scheffer & Trotter (1993). Acta Cryst. B49, 905-909].
