Triaqua-chlorido(1,10-phenanthroline-κN,N')cobalt(II) chloride monohydrate.

In the title compound, [CoCl(C(12)H(8)N(2))(H(2)O)(3)]Cl·H(2)O, the Co(II) ion is coordinated by two N atoms from the 1,10-phenanthroline ligand [Co-N = 2.125 (6) and 2.146 (6) Å], one chloride ligand [Co-Cl = 2.459 (2)Å] and three water mol-ecules [Co-O = 2.070 (5)-2.105 (5)Å] in a distorted octa-hedral geometry. Inter-molecular O-H⋯Cl and O-H⋯O hydrogen bonds form an extensive three-dimensional hydrogen-bonding network, which consolidates the crystal packing.
