Bis[4-chloro-N′-(2-pyridylmethylidene)benzohydrazidato]cobalt(III) nitrate sesquihydrate

Abstract

In the title compound, [Co(C13H9ClN3O)2]NO3·1.5H2O, the central Co3+ atom in the cation is coordinated by four N and two O atoms from the two tridentate ligands in a distorted octahedral fashion. In the crystal, the cobalt complex cations are linked to the half-occupied and the fully occupied water molecules, and the nitrate anion via classical intermolecular O—H...O and O—H...N hydrogen bonds and weak C—H...O contacts.
