The title compound, [Cd(C6H6N4)3]CO3, is composed of discrete cations and anions, which are each located on a twofold rotation axis. The central CdII ion exhibits a distorted octahedral geometry and is coordinated by six N atoms from three 2,2′-biimidazole molecules. The crystal packing is stabilized by N—H⋯O hydrogen bonds.

In the title complex, [Cu(C9H8NO3)(C10H8N2)2]ClO4·2H2O, the CuN4O2 chromophore exhibits a square-pyramidal geometry that is distorted towards octa­hedral owing to an intra­molecular Cu⋯O contact from the double-bond carboxyl­ate O atom. The cations, anions and solvent water mol­ecules are linked by hydrogen bonds into a linear chain running along the b axis. [ABSTRACT FROM AUTHOR]

In the title compound, C17H18N42+·2Cl−·2H2O, anions, cations and water mol­ecules are linked into a two-dimensional framework by a combination of inter­molecular N—H⋯O, N—H⋯Cl and O—H⋯Cl hydrogen bonds. [ABSTRACT FROM AUTHOR]

The title compound, C21H17N3O2, is a norbornene derivative containing an azo group which is disordered over two sites in an approximate 2:1 ratio. The two aromatic rings are almost coplanar [dihedral angle 9.25 (10)°]. The crystal packing is stabilized by an intermolecular C—H...O hydrogen bond. [ABSTRACT FROM AUTHOR]

In the title compound, [Cd(C2H4O2)(C12H8N2)2]ClO4·H2O, the CuII ion is in a distorted octahedral coordination geometry with normal Cd—O and Cd—N bond lengths. The cation and anion both lie on crystallographic twofold axes. In the crystal structure, intermolecular O—H...O hydrogen bonds form one-dimensional chains along [100] and in addition weak π–π stacking interactions connect molecules along [001]. The Cg1 (central fused benzene ring) and Cg2 (outer fused pyridine ring) centroid–centroid and perpendicular distances are 3.746 (2) and 3.623 (2) Å, respectively, with Cg1... Cg2i = 3.602 (2) Å [symmety code: (i) − x, 1 − y, 1 − z]. [ABSTRACT FROM AUTHOR]

In the title compound, [Cu(C17H16N4)2](NO3)2·2C2H5OH, the CuII ion lies on a crystallographic twofold rotation axis and is in a distorted square-planar coordination geometry formed by four N atoms from two 1,3-bis(benzimidazol-2-yl)propane ligands. The N—Cu—N angles range from 90.25 (7) to 144.89 (11)°. In the crystal structure, a two-dimensional framework is formed by a combination of N—H...O and O—H...O hydrogen bonds. [ABSTRACT FROM AUTHOR]

In the title dimeric complex, [Cu2(C2O4)Cl2(C12H8N2)2], which lies on a crystallographic inversion center, the CuII ion is in a distorted trigonal–bipyramidal coordination geometry formed by two N atoms from a phen ligand, two O atoms from a bridging oxalate ligand and one Cl atom. In the crystal structure, pairs of mol­ecules related by π–π stacking inter­actions are stacked along the c-axis direction [ABSTRACT FROM AUTHOR]

The mol­ecule of the title compound, C14H28N2O4P2S2, possesses a crystallographically imposed inversion centre. The mol­ecular structure is stabilized by two C—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]

In the title compound, [Cd(C8H4O4)(C10H8N2)(H2O)2] n, the Cd atom has a distorted trigonal–prismatic coordination geometry, bonded to two N atoms from the 2,2′-bipyridine ligand, two water O atoms and two O atoms from two different phthalate ligands, thereby producing a linear coordination polymer. The crystal structure is stabilized by π–π interactions [centroid-to-centroid distance = 3.766 (3) Å] and hydrogen bonds. [ABSTRACT FROM AUTHOR]

The title molecule, C14H8Cl2N2O2, is a trans-azobenzene which has a crystallographic inversion center at the mid-point of the N=N bond [N=N = 1.228 (4) Å]. There are neither hydrogen bonds nor π–π interactions between the aromatic rings, and the crystal structure is stabilized by van der Waals interactions. [ABSTRACT FROM AUTHOR]

The title compound, C10H11N5O3S, was obtained unintentionally when our group attempted to synthesize a precursor of a copper corrosion inhibitor using p-acetylamidobenzenesulfonyl chloride and 3-amino-1- H-1,2,4-triazole. In the molecule the dihedral angle between the benzene ring and the triazole ring is 85.10 (6)°. In the crystal structure, molecules are linked by N—H...O and N—H...N hydrogen bonds to form a three-dimensional network. [ABSTRACT FROM AUTHOR]
