Ethane-1,2-diyl bis(pyridine-3-carboxylate)
The title compound, C(14)H(12)N(2)O(4), has twofold imposed crystallographic symmetry in the solid state. The asymmetric unit contains one half-mol-ecule. An intra-molecular C-H⋯O hydrogen bond is formed between the carboxyl-ate O group and one H atom of the aromatic ring such that a five-membered ring is formed. The angle between the planes of symmetry-related aromatic rings is 44.71 (19)°.

The central structural motif of the title coordination polymer, [Co(NO3)2(C4H4N2)(CH3CN)2(H2O)2] n , is a chain composed of Co(II) ions linked by bis-monodentate bridging pyrazine ligands through their N atoms. The Co(II) ion is located on an inversion center and is additionally coordinated by two O atoms of water mol-ecules and two N atoms of aceto-nitrile mol-ecules. The resultant N4O2 coordi...

In the crystal structure, the title compound, C(16)H(14)S(4), is located on an inversion center and exhibits a gauche(+)-trans-gauche(-) conformation in the S-CH(2)-CH(2)-S bond sequence. The S-C=S plane makes a dihedral angle of 30.63 (17)° with the phenyl ring. An inter-molecular C-H⋯π inter-action is observed.

In the title polymeric complex, {[Zn(C24H22N6O2)(H2O)4](NO3)2·2H2O} n , the Zn(II) cation, located about a twofold rotation axis, is coordinated by two imidazole groups and four water mol-ecules in a distorted N2O4 octa-hedral geometry; among the four coordinate water mol-ecules, two are located on the same twofold rotation axis. The 1,4-bis-[4-(1H-imidazol-1-yl)benzo-yl]piperazine] ligand is c...

In the structure of the title mol-ecular salt, C10H18N2 (2+)·2NO3 (-), the dinitrate salt of 4-(N,N-di-ethyl-amino)-aniline, the two ethyl groups lie almost perpendicular to the plane of the benzene ring [the ring-to-ethyl C-C-N-C torsion angles are -59.5 (2) and 67.5 (3)°]. The aminium groups of the cation form inter-species N-H⋯O hydrogen bonds with the nitro O-atom acceptors of both anions, ...
