The title compound, [CrNa(C16H9ClN2O2)2(C3H6O)2]n, is an azo-CrIII complex polymer that is used as a charge-control agent in electrophotography. The monomeric unit is composed of octahedral CrIII and NaI units, and is characterized by twofold rotation symmetry. The CrIII atom is chelated by two N and four O atoms from two [(5-chloro-2-oxidophenyl)diazenyl]-2-naphtholate ligands. The ligand anion exists in the cis form. The NaI atom is coordinated by two phenoxy O atoms from a neighboring CrIII unit, two naphthoxy O atoms from another neighboring CrIII unit and two O atoms from acetone molecules. The dinuclear complex forms a one-dimensional polymer running along the c axis.
