The title compound, [FeNa(C23H14ClN3O3)2(C3H6O)2]n, has a skeleton of an azo-FeIII anion complex with a sodium cation, used widely as a charge-control agent (CCA) of the negative type in electrophotography. In the FeIII anion-complex, the FeIII atom is coordinated by four carbonyl O atoms and two N atoms of the diazo groups from two azo ligands lying cis to each other. There are two N-HO intramolecular hydrogen bonds between the NH group and the carbonyl O atom. In the crystal structure, there exists a sodium-cation dimer bridged by the carbonyl O atoms at the periphery of the anion complex. An interesting aspect of this structure is that each sodium cation unites three different Fe-anion complexes through the carbonyl O atom, generating a quasi-two-dimensional network parallel to the (001) plane. At the same time, the sodium cation accommodates two acetone molecules, linked through the carbonyl O atom.
