1,2-Bis(2-chloro-benzyl-idene)hydrazine.

ABSTRACT: The title Schiff base compound, C(14)H(10)Cl(2)N(2), crystallizes with one half-mol-ecule in the asymmetric unit. The mid-point of the N-N bond [1.418 (3) Å] lies on an inversion centre. The mol-ecular skeleton is approximately planar, the largest deviation from the mean plane being 0.143 (4) Å for the N-bonded C atom. The crystal packing exhibits no classical inter-molecular hydrogen bonds.

1,2-Bis(3-phen-oxy-benzyl-idene)hydrazine.

Project description:Mol-ecules of the title compound, C(26)H(20)N(2)O(2), reside on crystallographic centres of inversion located at the mid-point of the N-N bond. The benzyl-idene ring is essentially coplanar with the central hydrazine group, with an inter-planar angle of 4.5?(2)°, whereas the phenyl ring is oriented at 34.0?(3)° with respect to the mean plane of the central 1,2-dibenzyl-idenehydrazine group. In the crystal, C-H??(arene)-ring inter-actions link mol-ecules about inversion centres.

(E,E)-1,2-Bis(2,4,5-trimeth-oxy-benzyl-idene)hydrazine.

Project description:The asymmetric unit of the title compound, C(20)H(24)N(2)O(6), contains one half-mol-ecule, the complete mol-ecule being generated by a crystallographic inversion centre. The mol-ecule is nearly planar with a dihedral angle between the two benzene rings of 0.03?(4)° and the central C/N/N/C plane making a dihedral angle of 8.59?(7)° with each of its two adjacent benzene rings. The two meth-oxy groups at the ortho and meta positions are slightly twisted [C-O-C-C torsion angles = 7.23?(12) and 5.73?(13)°], whereas the meth-oxy group at the para position is almost coplanar with the attached benzene ring [C-O-C-C torsion angle = -2.02?(13)°]. The crystal structure is stabilized by a weak C-H?? inter-action.

1,2-Bis(2-hy-droxy-5-methyl-benzyl-idene)hydrazine.

Project description:The mol-ecular structure of the title compound, C16H16N2O2, is stabilized by intra-molecular O-H?N hydrogen bonds with S(6) graph-set motifs, so that the mol-ecule is almost planar, with a C=N-N=C torsion angle of -179.7?(2)° and a dihedral angle of 1.82?(12)° between the aromatic rings. In the crystal, weak C-H?? inter-actions lead to the formation of a three-dimensional network.

Project description:The title mol-ecule, C(20)H(24)N(2)O(6), lies on an inversion centre. All non-H atoms are essentially coplanar, with an r.m.s. deviation of 0.0415 (1) Å and a maximum deviation of 0.1476 (1) Å for the meth-oxy C atom at the 4-position of the benzene ring. The crystal structure is stabilized by weak C-H⋯N and C-H⋯π inter-actions.

(E,E)-1,2-Bis[3-(prop-2-yn-1-yl-oxy)benzyl-idene]hydrazine.

Project description:The mol-ecule of the title compound, C(20)H(16)N(2)O(2), is centrosymmetric, the inversion center being located at the mid-point of the central azine bond. The conformation around the C=N bond is E. The whole mol-ecule (except for the H atoms) is essentially planar, with an r.m.s. deviation of 0.07 Å. In the crystal, mol-ecules are linked head-to-tail by pairs of C-H⋯O hydrogen bonds, forming inversion dimers, and resulting in the formation of chains propagating along [011].

(E,E)-1,2-Bis[4-(prop-2-yn-1-yl-oxy)benzyl-idene]hydrazine.

Project description:The mol-ecule of the title compound, C(20)H(16)N(2)O(2), is centrosymmetric with the mid-point of the central N-N bond located on an inversion center. The configuration around the C=N bond is E. The whole mol-ecule (except for the H atoms) is approximately planar, with an r.m.s. deviation of 0.07 Å. In the crystal, the presence of weak inter-molecular C-H⋯O hydrogen bonding involving each acetyl-ene H atom and the adjacent phen-oxy O atom results in the formation of supra-molecular chains.
