  • Abstract

    In this paper, an attempt has been made to carry out a crystallographic comparison of some geometrical and structural features for a series of androstane derivatives of steroids. Selected bond distances and bond angles of interest in a series of forty- five androstane derivatives have been discussed in detail, besides conformations of individual ring systems, their graphical presentation and their frequency of occurrence. Intra- and intermolecular interactions of the type X-H...A [X=C,O; A=O,Cl,Br,F] in androstane derivatives have been computed and discussed primarily on the basis of distance-angle scatter for better understanding of molecular packing in androstane derivatives.
