N,N′-Bis(5-bromo-2-hydroxybenzylidene)-2,2-dimethylpropane-1,3-diamine
The crystal structure of the title Schiff base compound, C(19)H(20)Br(2)N(2)O(2), contains two crystallographically independent mol-ecules (A and B) in the asymmetric unit, with similar conformations. Intra-molecular O-H⋯N (× 4) and C-H⋯N (× 5) hydrogen bonds form six- and five-membered rings, producing S(6) and S(5) ring motifs, respectively. One of the N atoms in mol-ecule A acts as a trifurc...
متن کاملN,N′-Bis(4-bromo-2-fluorobenzylidene)ethane-1,2-diamine
The mol-ecule of the title Schiff base compound, C(16)H(12)Br(2)F(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bonds. The imino groups are coplanar with the aromatic rings. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the dimethyl-ene bridge. An inter-esting feature of the ...
متن کامل5-Bromo-N 3-phenylpyrazine-2,3-diamine
In the title compound, C(10)H(9)BrN(4), the dihedral angle between the benzene and pyrazine rings is 61.34 (5)°. Inter-molecular N-H⋯N hydrogen bonds and N-H⋯π inter-actions assemble the mol-ecules into a three-dimensional network structure.

The mol-ecule of the title compound, [CuI(C(19)H(20)Cl(2)N(2))], lies across a crystallographic mirror plane. The coordination around the copper centre is distorted trigonal planar, with a bite angle of 94.40 (7)°. A six-membered chelate ring is formed by the coordination of iminic N atoms of the bidentate ligand to the Cu(I) atom, adopting a chair conformation. This conformation is required if...
متن کاملN′-(3-Ethoxy-2-hydroxybenzylidene)benzenesulfonohydrazide
There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(16)N(2)O(4)S, both of which are stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds lead to [101] chains of mol-ecules in the crystal structure.
