Abstract

Volume 2 of the Atlas of Steroid Structure contains complete crystal and molecular data on 42 estrane, 61 androstane, and 81 pregnane structures. It is designed to be a supplement to Volume 1. Formats of data presentation have been modified in order to conserve space. Sections of the text from Volume 1 have been included in the following discussion, but a review of the complete text is recommended in order to deal with the abbreviated format most effectively. Three pages of drawings, tables, and text are devoted to the crystallographic and molecular data on each steroid. The contents of each of the pages is as follows:
  1. Page 1.

    The IUPAC name, schematic drawings, crystal data, ring conformation, ring junction conformation, functional group distances, and two perspective (ORTEP) drawings based on atomic coordinates.

     
  2. Page 2.

    A small stereo ORTEP drawing, all bond distances, bond angles, and torsion angles in the steroid.

     
  3. Page 3.

    Three stereo packing patterns, close intermolecular contacts, the geometry of hydrogen bonds, and one or more least-squares planes.
