Abstract

The structure of the title compound, [Co(NO2)2(NH2CH2CH2NH2)2][Co(NO2)4(NH2CH2CH2NH2)]·H2O, was redetermined with a modern CCD-equipped diffractometer. In comparison with the original determination based on photographic data [Kushi et al. (1976 ▶). Inorg. Nucl. Chem. Lett. 12, 629–633], the current study allows the location of reliable postions for the H atoms and thus leads to better understanding of the interionic and intermolecular interactions. The crystal structure consists of an octahedrally coordinated cationic CoIII complex ion, an octahedrally coordinated anionic CoIII complex ion and a lattice water molecule. The complex cation, complex anion and lattice water molecule are connected by an intricate network of O—H⋯O and N—H⋯O hydrogen bonds, forming a three-dimensional structure.
