(Bis[2-(2-oxido-1-naphthylmethylideneamino)phenyl]disulfide)chloroiron(III).

The crystal structure of the title compound, (bis[2-(2-oxido-2-naphthylideneamino)phenyl] disulfide-kappa(5)O,N,S,N',O')chloroiron(III), [FeCl(C(34)H(22)N(2)O(2)S(2))], has been determined. The structure consists of monomeric iron(III) complexes with distorted octahedral coordination. The disulfide functions as a pentadentate ligand and the Fe(III) atom is coordinated through two N, two O and one S atom, and one chloride ion. The distance between the second S atom and the Fe(III) atom is a non-bonding 3.8473 (14) A.

5-Chloro-N-(2-hydroxy-5-methylphenyl)salicylaldimine.

The title compound, N-(5-chloro-2-oxidobenzylidene)-2-hydroxy-5-methylanilinium, C(14)H(12)ClNO(2), is a tridentate Schiff base with almost planar molecules. Each molecule contains a strong intramolecular N-H.O hydrogen bond [2.576 (2) A]. There is also an intermolecular O-H.O hydrogen bond [2.695 (2) A] linking neighbouring molecules into infinite chains along the [101] direction.

A complex containing both five- and six-coordinate

The title compound, aquachloro4,4'-dibromo-2, 2'-[o-phenylenebis(nitrilomethylidyne)]diphenolato-O,N,N', O'iron(III)-chloro4,4'-dibromo-2, 2'-[o-phenylenebis(nitrilomethyli-dyne)]diphenolato-O,N,N', O'iron(III)-dimethylformamide (1/1/1), [FeCl(C(20)H(12)Br(2)N(2)O(2))][FeCl(C(20)H(12)Br(2)N(2)O(2))(H(2)O)] .C(3)H(7)NO, contains one independent five-coordinate [FeCl(C(20)H(12)Br(2)N(2)O(2))] monomer, one six-coordinate [FeCl(C(20)H(12)Br(2)N(2)O(2))(H(2)O)] 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-H.O hydrogen bonds. Apart from these hydrogen bonds, there are also intermolecular C-H.Cl and C-H.O contacts.

[N,N'-Bis(5-bromosalicylidene)-1,3-diaminopropane]nickel(II) and [N, N'-bis(5-chlorosalicylidene)-1,3-diaminopropane]copper(II).

The title compounds, ¿4,4'-dibromo-2,2'-[1, 3-propanediylbis(nitrilomethylidyne-N)]diphenolato-O,O '¿nickel(II), [Ni(C(17)H(14)Br(2)N(2)O(2))], and ¿4,4'-dichloro-2,2'-[1, 3-propanediylbis(nitrilomethylidyne-N)]diphenolato-O,O '¿copper(II), [Cu(C(17)H(14)Cl(2)N(2)O(2))], lie on crystallographic twofold axes. In both structures, the metal coordination sphere is a tetrahedrally distorted square plane formed by the four-coordinate N(2)O(2) donor set of the Schiff base imine-phenol ligands. In the Ni compound, the Ni-O and Ni-N distances are 1.908 (3) and 1.959 (4) A, respectively, while in the Cu compound, the Cu-O and Cu-N distances are 1.907 (2) and 1.960 (2) A, respectively. The two Schiff base moieties, which themselves are nearly planar, are inclined at an angle of 29.26 (7) degrees for the Ni compound and 29.26 (5) degrees for the Cu compound.
