N-(2-Bromobenzyl)-N′-(2-pyridyl)benzene-1,2-diamine
In the title compound, C(18)H(16)BrN(3), mol-ecules are linked into dimers by co-operative inter-molecular N-H⋯N hydrogen bonding. Only one N-H group is involved in hydrogen bonding. The planes of the pyridine and bromo-phenyl rings are twisted by 61.49 (3) and 79.11 (8)°, respectively, from the plane of the central phenyl ring.
متن کاملN,N′-Bis(2-thienylmethylene)benzene-1,4-diamine
The Schiff base, C(16)H(12)N(2)S(2), has been synthesized by refluxing an ethano-lic solution of thio-phene-2-carbaldehyde and benzene-1,4-diamine. The center of the benzene ring is located on a crystallographic center of inversion. The dihedral angle between the benzene and thio-phene rings is 63.6 (1)°.
متن کامل4-Nitro-N^2^-(pyridin-4-ylmethylidene)benzene-1,2-diamine
In the title compound, C12H10N4O2, the dihedral angle between the aromatic rings is 43.18 (16)°. The nitro group is rotated from its attached ring by 7.8 (2)° and a short intra-molecular N-H⋯N contact occurs. In the crystal, the mol-ecules are linked by N-H⋯N and C-H⋯O hydrogen bonds, generating a three-dimensional network.
متن کاملDichlorido[N-(2-pyridylmethylidene)benzene-1,4-diamine]zinc(II)
In the title compound, [ZnCl(2)(C(12)H(11)N(3))], the Zn(II) atom is four-coordinated by two N atoms from an N-(2-pyridylmethyl-ene)benzene-1,4-diamine ligand and two Cl atoms in a distorted tetra-hedral geometry. In the crystal, the complex mol-ecules are connected by N-H⋯Cl and C-H⋯Cl hydrogen bonds into a two-dimensional layer structure parallel to (110).
متن کاملN,N′-Bis(4-methylbenzylidene)benzene-1,4-diamine
The centrosymmetric title compound, C(22)H(20)N(2), crystallizes with one half-mol-ecule in the asymmetric unit. The dihedral angle between the central and outer benzene rings is 46.2 (2)°.
متن کاملN,N′-Bis(pyridin-2-yl)benzene-1,4-diamine–quinoxaline (2/1)
The asymmetric unit of the title compound, 2C(16)H(14)N(4)·C(8)H(6)N(2), consits of one mol-ecule of N,N'-bis-(pyridin-2-yl)benzene-1,4-diamine (PDAB) and one half-mol-ecule of quinoxaline (QX) that is located around an inversion centre and disordered over two overlapping positions. The PDAB mol-ecule adopts a non-planar conformation with an E configuration at the two partially double exo C N b...
