The title compound, C21H32O4 crystallizes in a triclinic unit cell, which is very unusual for steroids. The asymmetric unit contains two independent molecules with almost identical geometry, although they are slighly twisted in opposite directions. These molecules form a dimer interconnected via hydrogen bonds. Both molecules have a cis A/B ring junction characteristic of a 5β-configuration, but differ in the orientation of their hydroxyl groups.
organic compounds
In the title compound, C3H7NO2·NH4+·NO3-, the sarcosine zwitterions have an almost perfectly planar N-C-COO main chain and assemble in chains via hydrogen bonds. The ammonium and nitrate ions are arranged in sheets that alternate with sheets of sarcosine chains. The whole structure is stabilized by an extensive three-dimensional network of hydrogen bonds.
metal-organic compounds
The title compound, (C6H15N4O2)3·CrF6·3H2O, is isostructural with the vanadium analogue. One of the argininium cations is partially disordered over two different conformations. A complex network of N—HO, N—HF, O—HO and O—HF hydrogen bonds supports the structure.
