Crystal structure of bis{4-bromo-2-[(carbamimidamidoimino)methyl]phenolato-κ3 N,N′,O}cobalt(III) nitrate dimethylformamide monosolvate
The title compound, [Co(C8H8BrN4O)2]NO3·C3H7NO, is formed of discrete [CoL 2](+) cations, nitrate anions and di-methyl-formamide (DMF) mol-ecules of crystallization. The cation has no crystallographically imposed symmetry. The ligand mol-ecules are deprotonated at the phenol O atom and octa-hedrally coordinate the Co(III) atoms through the azomethine N and phenolate O atoms in a mer configurati...

In the title compound, C6H4BrN3O4, the dihedral angles between the nitro groups and the aniline ring are 2.04 (3) and 1.18 (4)°, respectively. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds and weak side-on C-Br⋯π inter-actions [3.5024 (12) Å] link adjacent mol-ecules, forming a three-dimensional network. A close O⋯Br contact [3.259 (2) Å] may also add additional stability.

The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial mol-ecular packing disorder such that a 180° rotation of the mol-ecule about the phenol C-O bond results in disorder of the bromine and nitrile groups. The disorder has been parameterized as a disorder of only the bromine and nitrile substituents on a unique phenol ring. An intra-molecular O-H⋯Br con...

The title dinuclear copper(II) complex [Cu2(C18H16Br2N2O4S2)2] was prepared by direct synthesis of a dianionic Schiff base derived from 5-bromo-salicyl-aldehyde and cyste-amine. The discrete mol-ecules lie across inversion centers and crystallize with two di-methyl-formamide (DMF) mol-ecules of crystallization. The unique CuII ion is four-coordinated by two tetra-dentate Schiff base ligands in ...

In the title compound, C17H11Br2N3O4, the dihedral angle between the planes of the naphthalene system and the benzene ring is 52.86 (8)°. The nitro substituent and the attached naphthalene system are almost coplanar [dihedral angle = 5.6 (4)°], probably as a consequence of an intra-molecular N-H⋯O hydrogen bond with the amine group. The nitro substituent attached to the benzene ring is disorder...
