ABSTRACT: The cation of the title salt, C(18)H(20)N(4) (2+)·2HSO(4) (-)·2H(2)O, lies on a center of inversion with the mid-point directly in the middle of the p-phenyl-ene ring. Within the hydrogensulfate ion, the S-O(H) bond is the longest of the S-O bonds. The dihedral angle between the central and terminal ring of the cation is 78.6?(2)°. In the crystal, the cation, anion and water mol-ecule inter-act by O-H?O and N-H?O hydrogen bonds, generating a three-dimensional network.

The cation of the title salt, C(18)H(20)N(4) (2+)·2HSO(4) (-)·2H(2)O, lies on a center of inversion with the mid-point directly in the middle of the p-phenyl-ene ring. Within the hydrogensulfate ion, the S-O(H) bond is the longest of the S-O bonds. The dihedral angle between the central and terminal ring of the cation is 78.6 (2)°. In the crystal, the cation, anion and water mol-ecule inter-act by O-H⋯O and N-H⋯O hydrogen bonds, generating a three-dimensional network. ...[more]

2,2'-[1,2-Phenyl-enebis(aza-nedi-yl)]di-aceto-nitrile.

Project description:The title compound, C10H10N4, shows chemical but not crystallographic C2 symmetry. The two cyano-methyl groups are located in an anti position with respect to the aromatic ring. In the crystal, mol-ecules form parallel ladder-like tapes linked through two N-H?N hydrogen bonds. Further weak intra-molecular N-H?N hydrogen bonding is responsible for the elongation of one of the Caromatic-N bonds.

2,2'-{1,1'-[2,2'-Oxalylbis(hydrazin-2-yl-1-yl-idene)]diethyl-idyne}dipyridinium bis-(perchlorate) dihydrate.

Project description:The title salt, C(16)H(18)N(6)O(2) (2+)·2ClO(4) (-)·2H(2)O, was obtained unintentionally as a major product in the reaction of Zn(ClO(4))(2)·6H(2)O with the N',N'(2)-bis-[(1E)-1-(2-pyrid-yl)ethyl-idene]ethanedihydrazide (H(2)L) ligand. The (H(4)L)(2+) cation lies across a centre of inversion. The pyridiniumimine fragments of (H(4)L)(2+) adopt syn orientations. Intra-molecular N-H⋯N and N-H⋯O hydrogen bonds lead to the formation of S(5) motifs. In the crystal, neighbouring cations are connected by π-π inter-actions between pyridinium units with a centroid-centroid distance of 3.600 (1) Å. Moreover, the crystal components are assembled into two-dimensional layers via N-H⋯O and O-H⋯O hydrogen bonds, with no direct hydrogen-bonding inter-actions between cations.

{5,5'-Dihydr-oxy-2,2'-[o-phenyl-enebis-(nitrilo-methyl-idyne)]diphenolato}nickel(II) dihydrate.

Project description:In the title complex, [Ni(C(20)H(14)N(2)O(4))]·2H(2)O, the Ni(II) ion is in an essentially square-planar geometry involving an N(2)O(2) atom set of the tetra-dentate Schiff base ligand. The Ni atom lies on a crystallographic twofold rotation axis. The asymmetric unit contains one half-mol-ecule of the complex and a water mol-ecule. An inter-molecular O-H?O hydrogen bond forms a four-membered ring, producing an R(1) (2)(4) ring motif involving a bifurcated hydrogen bond to the phenolate O atoms of the complex mol-ecule. In the crystal structure, mol-ecules are linked by ?-? stacking inter-actions, with centroid-centroid distances in the range 3.5750?(11)-3.7750?(11)?Å. As a result of the twofold symmetry, the central benzene ring makes the same dihedral angle of 15.75?(9)° with the two outer benzene rings. The dihedral angle between the two hydroxy-phenyl rings is 13.16?(5)°. In the crystal structure, mol-ecules are linked into infinite one-dimensional chains by directed four-membered O-H?O-H inter-actions along the c axis and are further connected by C-H?O and ?-? stacking into a three-dimensional network. An inter-esting feature of the crystal structure is the short Ni?O, O?O and N?N inter-actions which are shorter than the sum of the van der Waals radii of the relevant atoms. The crystal structure is stabilized by inter-molecular O-H?O and C-H?O hydrogen bonds and by ?-? stacking inter-actions.

4,4'-Di-tert-butyl-2,2'-dipyridinium dichloride.

Project description:In the title compound, C(18)H(26)N(2) (2+)·2Cl(-), the complete dication is generated by crystallographic inversion symmetry; both N atoms are protonated and engaged in strong and highly directional N-H?Cl hydrogen bonds. Additional weak C-H?Cl contacts promote the formation of a tape along ca. [110]. The crystal structure can be described by the parallel packing of these tapes. The crystal studied was a non-merohedral twin with twin law [-1 0 0, 0 -1 0, -0.887 0.179 1] and the final BASF parameter refining to 0.026?(2) .

Crystal structure, Hirshfeld surface analysis and anti-oxidant capacity of 2,2'-{(1E,1'E)-[1,2-phenyl-enebis(aza-nylyl-idene)]bis-(methanylyl-idene)}bis-(5-benz-yloxy)phenol.

Project description:The whole mol-ecule of the title Schiff base compound, C34H28N2O4, is generated by mirror symmetry, with the mirror bis-ecting the central benzene ring. It was synthesized via the condensation reaction of 1,2-di-amine-benzene with 4-benz-yloxy-2-hy-droxy-benzaldehyde. The mol-ecule is V-shaped and there are two intra-molecular O-H?N hydrogen bonds present forming S(6) ring motifs. The configuration about the C=N imine bonds is E. The central benzene ring makes dihedral angles of 41.9?(2) and 43.6?(2)° with the phenol ring and the outer benz-yloxy ring, respectively. The latter two rings are inclined to each other by 84.4?(2)°. In the crystal, mol-ecules are linked by C-H?? inter-actions, forming layers lying parallel to the ab plane. The Hirshfeld surface analysis and the two-dimensional fingerprint plots confirm the predominance of these inter-actions in the crystal structure. The anti-oxidant capacity of the compound was determined by the cupric reducing anti-oxidant capacity (CUPRAC) process.

The water mol-ecule was found to be disordered over two positions [ratio 0.80 (1):0.20 (1)] and the major component is linked to the complex via an O-H⋯O hydrogen bond.
