Diaqua­bis[ N-benzoyl- N′-(isonicotino­yl)hydrazine]dichloro­cobalt(II) dihydrate.

In the title complex, [CoCl2(C13H11N3O2)2(H2O)2]·2H2O, each CoII atom occupies an inversion center and is coordinated by two water mol­ecules, two Cl− anions and two N-benzoyl- N′-(isonicotino­yl)hydrazine ligands in a distorted octa­hedral geometry. The asymmetric unit contains two half-complexes. The three-dimensional supra­molecular architecture is stabilized by inter­molecular hydrogen bonding. [ABSTRACT FROM AUTHOR]
