摘要：

Merely the change of the solvent for the crystallization of the title compound leads to different crystal modifications. In the orthorhombic crystals (from n‐hexane) a methoxy group is twisted out of the C6 plane (see structure). In the monoclinic crystals (from diisopropyl ether) all four methoxy groups lie in the plane of the C6 rings. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
