Bis[4-chloro-N'-(2-pyridyl-methyl-idene)benzohydrazidato]cobalt(III) nitrate sesquihydrate.

In the title compound, [Co(C(13)H(9)ClN(3)O)(2)]NO(3)·1.5H(2)O, the central Co(3+) atom in the cation is coordinated by four N and two O atoms from the two tridentate ligands in a distorted octa-hedral fashion. In the crystal, the cobalt complex cations are linked to the half-occupied and the fully occupied water mol-ecules, and the nitrate anion via classical inter-molecular O-H⋯O and O-H⋯N hydrogen bonds and weak C-H⋯O contacts.
