cis-Aqua­chloridobis(1,10-phenanthroline-κ(2) N,N′)cobalt(II) chloride 2.5-hydrate

In the title complex, [CoCl(C(12)H(8)N(2))(2)(H(2)O)]Cl·2.5H(2)O, the Co(II) ion is coordinated by four N atoms of two bis-chelating 1,10-phenanthroline (phen) ligands, one water mol­ecule and a chloride ligand in a distorted octa­hedral environment. The dihedral angle between the two phen ligands is 84.21 (3)°. In the crystal structure, complex mol­ecules and chloride ions are linked into centrosymmetric four-component clusters by inter­molecular O—H⋯Cl hydrogen bonds. Of the 2.5 solvent water mol­ecules in the asymmetric unit, two were refined as disordered over two sites with fixed occupancies of ratios 0.50:0.50 and 0.60:0.40, while another was refined with half occupancy.
