(1E,1'E)-4,4'-[1,1'-(Hydrazine-1,2-diyl-idene)bis-(ethan-1-yl-1-yl-idene)]diphenol dihydrate.

ABSTRACT: The asymmetric unit of the title compound, C(16)H(16)N(2)O(2)·2H(2)O, contains one half-mol-ecule of diphenol and one water mol-ecule. The complete diphenol mol-ecule is generated by a crystallographic inversion centre. In the mol-ecule, the central C(meth-yl)-C=N-N=C-C(meth-yl) plane makes a dihedral angle of 8.88?(6)° with its adjacent benzene ring. In the crystal, the components are linked by O-H?N and O-H?O hydrogen bonds into a three-dimensional network. The crystal structure is further stabilized by a weak C-H?? inter-action.

2,2'-{[(1E,1'E)-(Cyclo-hexane-1,4-diyl)-bis(aza-nylyl-idene)]bis-(ethan-1-yl-1-yl-idene)}diphenol.

Project description:The title compound, C22H26N2O2, crystallizes with three independent mol-ecules, two of which are situated on inversion centers, so the asymmetric unit contains two independent half-mol-ecules and one mol-ecule in a general position. The two hy-droxy groups in each mol-ecule are involved in intra-molecular O-H?N hydrogen bonds, which generate S(6) rings. In the crystal, weak inter-molecular C-H?? inter-actions link the mol-ecules into two crystallographically independent columns propagating along [001]; one column consists of mol-ecules in general positions, while the other column is built from alternating independent centrosymmetric mol-ecules.

Project description:The complete molecule of the title compound, C(18)H(20)N(2)O(4), is generated by inversion symmetry. The conformation around the C=N bond is E. With the exception of the eth-oxy substituent, the mol-ecule is essentially planar with an r.m.s. deviation of 0.0455?Å. In the crystal, mol-ecules are linked by O-H?N hydrogen bonds into a two-dimensional supra-molecular network parallel to the bc plane.

Project description:The title compound, crystallized as a methanol solvate, C(18)H(20)O(2)·CH(3)OH, is an inter-mediate in the synthesis of the anti-lipidemic agent clinofibrate. Mol-ecules are packed together with the methanol solvent molecule via two O-H?O hydrogen bonds. The third O-H?O hydrogen bond is between neighboring 4,4'-(cyclo-hexane-1,1-di-yl)diphenol mol-ecules. The dihedral angle between two benzene rings planes is 81.69?(6).

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:The title compound, C(17)H(14)Cl(4)N(2)O(2), is generated by crystallographic twofold symmetry. The two benzene rings are inclined to one another by 80.17?(10)°. There are two intra-molecular O-H?N hydrogen bonds, which make S(6) ring motifs. In the crystal, mol-ecules are linked by C-H?O and weak C-H?Cl inter-actions, forming a three-dimensional network.

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.

Project description:In the title complex, [Ni(NO3)2(C14H16N6O2)]·H2O, the Ni(II) atom, lying on a twofold rotation axis, is coordinated by a tetra-dentate 3,3'-{(1E,1'E)-1,1'-[ethane-1,2-diylbis(azan-1-yl-1-yl-idene)]bis-(ethan-1-yl-1-yl-idene)}di-pyrazine 1-oxide ligand and two mutually trans monodentate nitrate anions in a distorted o-cta-hedral geometry. The lattice water mol-ecule is located on a twofold rotation axis. The complex mol-ecules are linked by the water mol-ecules through O-H⋯O hydrogen bonds into a chain along [001]. Further C-H⋯O hydrogen bonds lead to the formation of a three-dimensional network.

(E)-1-Phenyl-2-({5-[(1E)-(2-phenyl-hydrazin-1-yl-idene)meth-yl]-2-thien-yl}methyl-idene)hydrazine.

Project description:The title mol-ecule, C(18)H(16)N(4)S, adopts a U-shape with the aromatic groups lying syn and orientated in the same direction as the thio-phene S atom. The conformation about each of the C=N bonds is E. Overall, the mol-ecule is curved as seen in the dihedral angle of 30.26 (19)° formed between the terminal benzene rings. In the crystal, supra-molecular chains along the c axis are formed by a combination of N-H⋯N hydrogen bonds and N-H⋯π inter-actions.
