The title compound, aquachloro{4,4′-dibromo-2,2′-[ o-phenylenebis(nitrilomethylidyne)]diphenolato- O, N, N′, O′}iron(III)-chloro{4,4′-dibromo-2,2′-[ o-phenylenebis(nitrilomethyli-dyne)]diphenolato- O, N, N′, O′}iron(III)-dimethylformamide (1/1/1), [FeCl(C20H12Br2N2O2)][FeCl(C20H12Br2N2O2)(H2O)]·C3H7NO, contains one independent five-coordinate [FeCl(C20H12Br2N2O2)] monomer, one six-coordinate [FeCl(C20H12Br2N2O2)(H2O)] monomer and a non-coordinating dimethylformamide solvent molecule in the asymmetric unit. In the five-coordinate monomer, the Fe atom shows distorted square-pyramidal geometry, with the N and O atoms of the ligand at the base and the Cl atom at the apex of the pyramid. In the six-coordinate monomer, the Fe atom is in a distorted octahedral geometry and coordinated by the donor atoms of the tetrafunctional ligand in the horizontal plane, and the coordination sphere is completed by the O atom of the water molecule and the Cl atom at the axial positions. The title compound contains intermolecular O-H⃛O hydrogen bonds. Apart from these hydrogen bonds, there are also intermolecular C-H⃛Cl and C-H⃛O contacts. [ABSTRACT FROM AUTHOR] |
