Single crystal x-ray diffraction study of the molecular structures of six cobalt and rhodium compounds : an investigation of spontaneous resolution in coordination compounds

The crystal and molecular structures of six compounds named hereafter were determined by single crystal x-ray diffraction methods using an Enraf- Nonius CAD-4 automated diffractometer. These determinations were made as a study of the phenomenon of conglomerate crystallization and, more specifically, to examine the process of spontaneous resolution in coordination compounds. This is a process by which a substance will crystallize from solution in an enantiomorphic form without the aid of a resolving agent. Some clues as to the mechanism of conglomerate crystallization are provided by these studies of the hydrogen bonding interactions between complex cations and their neighboring anions and cations and intramolecular hydrogen bonding between ligands of an individual cation.
