Deskripsi
In the title hydrated complex, [Co(C15H10ClN3)2]Cl2·4H2O, the complete dication is generated by \overline{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—H...Cl and C—H...O 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.
