2,2'-Dihydroxy-3,3'-[(1E,1'E)-hydrazine-1,2-diylidenedimethylidyne]dibenzoic acid N,N-dimethylformamide disolvate.

ABSTRACT: The title compound, C(16)H(12)N(2)O(6)·2C(3)H(7)NO, lies across a crystallographic inversion centre which is situated at the midpoint of the central N-N bond. The substitution at the C=N bond adopts a trans configuration and it is essentially coplanar with the benzene ring [N-C-C-C torsion angles = -173.9?(4) and 6.4?(6)°]. All torsion angles involving non-H atoms are close to 180°. Intra-molecular O-H?O and weak C-H?O hydrogen bonds form S(6) and S(5) ring motifs, respectively, while inter-molecular O-H?O and weak C-H?O hydrogen bonds connect the Schiff base mol-ecule to solvent dimethyl-formamide mol-ecules.

The title compound, C(16)H(12)N(2)O(6)·2C(3)H(7)NO, lies across a crystallographic inversion centre which is situated at the midpoint of the central N-N bond. The substitution at the C=N bond adopts a trans configuration and it is essentially coplanar with the benzene ring [N-C-C-C torsion angles = -173.9 (4) and 6.4 (6)°]. All torsion angles involving non-H atoms are close to 180°. Intra-molecular O-H⋯O and weak C-H⋯O hydrogen bonds form S(6) and S(5) ring motifs, respectively, while inter-mole ...[more]

6,6'-Dimeth-oxy-2,2'-{[(E,E)-hydrazine-1,2-diyl-idene]bis-(methanylyl-idene)}diphenol methanol disolvate.

Project description:The title compound, C(16)H(16)N(2)O(4)·2CH(3)OH, is a hydrazone in an E geometric arrangement, with an inversion centre at the mid-point of the N-N bond. A symmetry-related pair of six-membered hydrogen-bonded rings [graph-set motif S(1) (1)(6)] are present for the terminal vanillin-imine moieties. Two lattice methanol solvent mol-ecules are present per formula unit (Z' = 1/2), which form hydrogen-bonded chains along [010] with two orientations due to disorder of the methanol H-atom.

Project description:In the title compound, C(14)H(10)O(6)S(2), the dihedral angle between the planes of the two phenyl-ene rings is 55.9?(1)°. Both hydr-oxy groups form intra-molecular hydrogen bonds; however, one of them also engages in inter-molecular hydrogen bonding.

2,2'-Dinitro-5,5'-dithio-dibenzoic acid.

Project description:In the title compound, C(14)H(8)N(2)O(8)S(2), the asymmetric unit contains two independent 2,2'-dinitro-5,5'-dithio-dibenzoic acid (Dina) mol-ecules with roughly the same conformation. In the crystal structure, strong inter-molecular O-H⋯O hydrogen bonds link the organic mol-ecules into a one-dimensional zigzag chain along the a axis. The dihedral angles between the two aromatic rings [109.3 (2) and 103.1 (3)°] are larger than that (88.95°) observed in a structure of the compound with a solvent water mol-ecule [Shefter & Kalman (1969), J. Chem. Soc. D, p. 1027]. Such a difference may be explained by the occurrence of O-H⋯O hydrogen bonds involving the water mol-ecule in the previously reported structure.

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.

4,4'-(Anthracene-9,10-di-yl)dibenzoic acid dimethyl-formamide disolvate.

Project description:In the title compound, C(28)H(18)O(4)·2C(3)H(7)NO, the dihedral angle between the benzene rings and the anthracene system is 74.05?(12)°. A crystallographic inversion centre is located in the middle of the anthracene unit. The dimethyl-formamide solvent mol-ecules are partially disordered over two positions of approximately equal occupancy [0.529?(6):0.471?(6)]. Inter-molecular O-H?O hydrogen bonds with the major occupancy formamide O atom as acceptor result in the formation of 2:1 solvate-complex aggregates, which are alternately linked to shorter solvate units via weak inter-molecular C-H?O contacts generated from the rotational disorder of the formamide O atom (minor occupancy component). Weak C-H?? inter-actions between the solvent mol-ecules as the donor and the outer anthracene rings support these contacts in the crystal structure for both disorder components.

Project description:In the title compound, C(17)H(10)F(6)O(4), the two benzene rings are twisted with respect to each other, making a dihedral angle of 67.43?(12)°. In the crystal, adjacent mol-ecules are linked by O-H?O and C-H?F hydrogen bonding, forming a wave-like layered supra-molecular structure.

(1E,2E)-1,2-Bis[(1-benzyloxymethyl-1H-indol-3-yl)methylidene]hydrazine.

Project description:The title compound, C(34)H(30)N(4)O(2), lies on an inversion center and consists of two 3-substituted-1H-indole units linked by a 1,2-dimethyl-enehydrazine bridge. It is one of numerous examples in which two aromatic ring systems are joined by this 4-atom bridge. The geometry of the centrosymmetric bridge is: C(arom)-C = 1.444?(3), C=N = 1.284?(3), N-N = 1.414?(4)?Å, C(arom)-C=N = 122.6?(2) and C=N-N = 111.9?(2)°. The nine non-H atoms of the indole unit lie in a plane (?(r.m.s.) = 0.0089?Å) which is twisted 6.0?(2)° with respect to the hydrazine bridge plane. The benzyl-oxymethyl substituents do not lie in the plane of the rest of the mol-ecule and are in a folded rather than an extended conformation. This is described by the three torsion angles in the middle of the C=N-C-O-C(Bz) group, viz. 98.5?(3), -62.1?(3), and -66.3?(2)°.

(1E,2E)-1,2-Bis[1-(3-nitro-phen-yl)ethyl-idene]hydrazine.

Project description:The asymmetric unit of the title compound, C(16)H(14)N(4)O(4), contains one half-mol-ecule of (nitro-phen-yl)ethanimine and the complete mol-ecule is generated by a crystallographic inversion centre. The mol-ecule has an E conformation with respect to each C=N double bond. The central C=N-N=C plane is twisted from the benzene rings with a dihedral angle of 24.76?(11)°. In the crystal, C-H?O inter-actions link the molecules to form sheets that lie parallel to (10-4).

(1E,2E)-1,2-Bis(2,3-dihydro-1H-inden-1-yl-idene)hydrazine.

Project description:In the title compound, C(18)H(16)N(2), there are two independent half-mol-ecules (A and B) in the asymmetric unit, each mol-ecule being completed by an inversion center situated in the mid-point of the central N-N bond. The mol-ecules themselves therefore are essentially planar with r.m.s. deviations of 0.015 (1) and 0.020 (1) Å, respectively. In the crystal, mol-ecules are connected via C-H⋯π inter-actions in which only type B mol-ecules are donors, while both A and B mol-ecules act as acceptors. As a result, type B mol-ecules are linked into infinite chains along b, which are inter-connected by molecules of type A.
