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

ABSTRACT: 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.

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. ...[more]

(E,E)-1,2-Bis[3-meth-oxy-4-(prop-2-yn-1-yl-oxy)benzyl-idene]hydrazine.

Project description:The complete mol-ecule in the title compound, C(22)H(20)N(2)O(4), is generated by the application of an inversion centre. With the exception of the terminal acetyl-ene groups [C-O-C-C = -78.02?(17)°], the remaining atoms constituting the mol-ecule are essentially coplanar. The configuration around the C=N bond [1.282?(2)?Å] is E. The formation of supra-molecular chains mediated by C-H?O inter-actions, occurring between methyl-ene H and meth-oxy O atoms, is the most notable feature of the crystal packing.

(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].

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.

(1E,2E)-1,2-Bis(2,3,4-trimeth-oxy-benzyl-idene)hydrazine.

Project description:The title compound, C(20)H(24)N(2)O(6), was obtained as an unexpected product by the reaction of hydrazinium dithio-carbazate with 2,3,4-trimeth-oxy-benzaldehyde in refluxing ethanol. The mol-ecule lies on a center of inversion. The crystal packing is stabilized by weak inter-molecular C-H?O inter-actions.

(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.

4-(Prop-2-yn-1-yl-oxy)benzene-1,2-dicarbonitrile.

Project description:In the title compound, C(11)H(6)N(2)O, the complete mol-ecule is generated by the application of crystallographic twofold symmetry (the mol-ecule is disordered about this axis). The prop-2-yn-1-yl residue is slightly twisted out of the plane of the benzene ring [C-O-C-C torsion angle = 173.1?(3)°] and is orientated away from the nitrile substituents. In the crystal, supra-molecular chains along the a axis, arising from C-H?N inter-actions, are connected into stacks along the c axis by ?-? inter-actions between the benzene rings [centroid-centroid distance = 3.6978?(6)?Å = length of the c axis].
