چکیده
The asymmetric unit of the title compound, [Mn(2)(C(20)H(12)Br(2)N(2)O(2))(2)Cl(2)]·2C(3)H(7)NO, contains one half of a centrosymmetric dinuclear Mn(III) complex and an N,N-dimethyl-formamide solvent mol-ecule. In the complex, the two Mn(III) ions are bridged by two O atoms from two symmetry-related N,N'-bis-(5-bromo-salicyl-idene)-1,2-diimino-benzene dianionic ligands with the longer Mn-O distance of 2.703 (3) Å, thus each Mn ion is six-coordinated by two N and three O atoms from the two dianionic ligands and one capping Cl atom in a distorted octa-hedral environment. The crystal structure displays inter-molecular π-π inter-actions between adjacent benzene rings, with a shortest centroid-centroid distance of 3.673 (2) Å, and inter-molecular C-H⋯O, C-H⋯ Cl and C-H⋯ Br hydrogen bonds.

The Schiff base ligand derived from the condensation of 3,5-dibromo-salicylaldehyde and 1,2-phenyl-enediamine, in the presence of dimethyl-formamide, forms the centrosymmetric title neutral binuclear distorted complex, [Cd(2)(C(20)H(10)Br(4)N(2)O(2))(2)(C(3)H(7)NO)(2)], with the two octa-hedral Cd atoms linked by two O atoms. All bond lengths and angles show normal values.

The structure of the title compound, [Fe(2)(C(17)H(16)N(2)O(2))(2)(OH)(2)]·2C(3)H(7)N, consists of centrosymmetric dimeric units in which crystallographically equivalent Fe(III) ions are doubly bridged by hydroxide groups. Each Fe(III) center in the complex has a six-coordinated distorted cis-FeN(2)O(4) octa-hedral geometry.

In the title compound, [Fe(2)(C(16)H(12)Br(2)N(2)O(2))(2)O], the complete mol-ecule is generated by twofold symmetry, with the bridging O atom, which links the iron centres, lying on the roatation rotation axis. The Fe(III) ion is chelated by the N,N,O,O-tetra-dentate Schiff base dianion, resulting in an FeN(2)O(3) square-based pyramid, with the two N atoms in the basal plane.
