Isostructurality in crystalline oxa-androgens: a case of C–O–H···O and C–H···O interaction mimicry and solid solution formation
Abstract
A C–H···O interaction in 2-oxa-4-androstene-3,17-dione is replaced by a C–O–H···O hydrogen bond in the isostructural 6α-hydroxy analogue, and these compounds form a binary solid solution, showing the similarity of these two crystal structures.
