N,N-Bis(4-meth-oxy-benzyl-idene)-3,3'-dimethyl-benzidine.

ABSTRACT: The mol-ecule of the title compund, C(30)H(28)N(2)O(2), a Schiff base synthesised via a condensation reaction between 4-meth-oxy-benzaldehyde and 3,3'-dimethyl-benzidine, a crystallographic twofold rotation axis passes through the mid-point of the C-C bond of the biphenyl unit. Thus, the asymmetric unit comprises one half-mol-ecule. In the biphenyl unit, the aromatic rings are twisted by 13.49?(7)° with respect to one another. The dihedral angles between the biphenyl and meth-oxy-benzene rings are 49.95?(12) and 50.06?(12)°. In the crystal, weak inter-molecular C-H? O hydrogen bonds contribute to the stabilization of the packing.

(4Z,6Z)-4,6-Bis(4-meth-oxy-benzyl-idene)-2,2-dimethyl-1,3-dioxan-5-one.

Project description:The title compound, C(22)H(22)O(5), crystallizes with two independent mol-ecules in the asymmetric unit, both of which possess pseudo-C(s) symmetry. The central 1,3-dioxanone rings have envelope conformations, with the C atom bearing the two methyl groups at the flap. The benzene rings of the meth-oxy-benzyl-idene units, attached in the 4- and 6-positions on the central 1,3-dioxanone rings, are tilted in the same direction with dihedral angles varying between 8.2?(1) and 18.1?(1)°. The crystal packing is influenced by ?-stacking inter-actions of the parallel displaced type [centroid-centroid distance of 3.723?(1)?Å for mol-ecule 1 and 3.884?(1)?Å for mol-ecule 2, with ring slippages of 1.432 and 1.613?Å, respectively] and the T-shaped type, with the long mol-ecular axes all aligned along [010].

N'-[Bis(benzyl-sulfan-yl)methyl-idene]-4-meth-oxy-benzohydrazide.

Project description:In the title compound, C(23)H(22)N(2)O(2)S(2), the dihedral angles between the 4-meth-oxy-substituted phenyl ring and the other two phenyl rings are 84.4?(4) and 77.7?(1)°, respectively, while the dihedral angle between the two phenyl rings is 57.5?(2)°. The amino group is not involved in an N-H hydrogen bond. The crystal packing is established by inter-molecular C-H?O packing inter-actions involving a relatively rare weak three-center hydrogen bond between the keto O atom and H atoms of the two nearby phenyl rings, which link the mol-ecules into chains running along the a axis. Additional weak inter-molecular hydrogen-bond inter-actions between the 4-meth-oxy O atom and one of the phenyl rings and provide added stability to the crystal packing.

1,5-Bis(4-meth-oxy-benzyl-idene)thio-carbonohydrazide methanol monosolvate.

Project description:In the title compound, C(17)H(18)N(4)O(2)S·CH(3)OH, the two benzene rings in the thio-carbonohydrazide mol-ecule form a dihedral angle of 22.42?(18)°. Pairs of N-H?S hydrogen bonds link thio-carbonohydrazide mol-ecules into centrosymmetric dimers. Methanol solvent mol-ecules serve as donors (O-H?S and O-H?N) and acceptors (N-H?O and C-H?O) of weak inter-molecular hydrogen bonds, which link further these dimers into double ribbons along the b axis.

1,5-Bis(2-meth-oxy-benzyl-idene)thio-carbonohydrazide methanol monosolvate.

Project description:The title compound, C17H18N4O2S·CH3OH, was synthesized by the condensation reaction of o-meth-oxy-benzaldehyde with thio-carbohydrazide in methanol. The two benzene rings are inclined each to other at 31.7 (1)°. Inter-molecular N-H⋯O and bifurcated O-H⋯N(S) hydrogen bonds link two thio-carbonohydrazide and two solvent mol-ecules into a centrosymmetric unit. These units, related by translation along the b axis, are further aggregated into columns through N-H⋯S hydrogen bonds.

Bis[4-hydr-oxy-N'-(4-meth-oxy-2-oxido-benzyl-idene-κO)benzohydrazidato-κO,N']cadmium(II) dimethyl sulfoxide disolvate.

Project description:The metal atom in the title compound, [Cd(C(15)H(13)N(2)O(4))(2)]·2C(2)H(6)OS, is twice O,N,O'-chelated by two symmetry-related Schiff base ligands to define a trans-N(2)O(4) octa-hedral geometry. Each anion occupies meridional sites of the octa-hedron; the metal atom lies on a special position of site symmetry 2. The dimethyl sulfoxide mol-ecule is a hydrogen-bond acceptor to the -NH- unit, and O-H⋯O hydrogen bonds link mol-ecules into a supra-molecular chain.

Project description:The title compound, C(28)H(22)Cl(2)N(2)O(2), crystallized with two independent mol-ecules (A and B) in the asymmetric unit.

Bis[?-4-hydr-oxy-N'-(4-meth-oxy-2-oxido-benzyl-idene)benzohydrazidato]bis-[pyridine-copper(II)].

Project description:In the title compound, [Cu(2)(C(15)H(12)N(2)O(4))(2)(C(6)H(5)N)(2)], each Cu(II) atom is chelated by the tridentate doubly deprotonated Schiff base and a pyridine mol-ecule in a nearly planar environment (r.m.s. deviation for all non-H atoms = 0.107?Å). The metal ions are bridged by one O atom from the symmetry-related Schiff base ligands, forming a centrosymmetric dinuclear copper(II) complex. The dimeric complex is linked to another dimer via weaker Cu-O inter-actions and also O-H?N hydrogen bonds.
