Abstract :
In the title hydrated complex, [Co(C15H10ClN3)2]Cl24H2O, the complete
dication is generated by 4 symmetry. The CoN6 moiety shows distortion from
regular octahedral geometry with the trans bond angles of two N—Co—N units
being 160.62 (9). In the crystal, O—HCl and C—HO interactions link the
components into (001) sheets. The title compound exhibits blue-light emission,
as indicated by photoluminescence data, and a HOMO–LUMO energy
separation of 2.23 eV was obtained from its diffuse reflectance spectrum.
