In the title mol-ecule, C(25)H(19)N(3)O(3)S(3), the tetra-hydro-pyridine ring adopts a half-chair conformation. The dihedral angle between the least-squares plane through the tetra-hydro-pyridine ring and two thio-phene and two benzene rings are 6.25 (9), 89.49 (9), 76.43 (9) and 84.93 (8)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetra-hydro-pyridine rings is 81...

In the binuclear title compound, [Ag2(C11H11N3)2](ClO4)2·2C2H6SO, the complex cation is centrosymmetric, with the unique Ag(I) cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridine-2-ylmeth-yl)pyridine-3-amine ligands in a geometry slightly distorted from linear [N-Ag-N = 170.78 (9)°], resulting in the formation of a 16-membered cyclic dimer. The two pyridine rings co...

The main interaction between pyridine and zeolites leads to form a hydrogen bond between the N atom of pyridine and OH groups of zeolites. The present work reports a theoretical study about the structural, vibrational and topological properties of the charge distribution of the molecular complexes between pyridine and a series of acids sites of zeolites. The calculated structural parameters...

The title compound, [CuCl(2)(C(18)H(18)N(8))]·2CH(3)OH·H(2)O, contains a penta-coordinated Cu(II) atom bonded to the tridentate 4,6-bis-[(E)-1-methyl-2-(pyridin-2-yl-methyl-idene)hydrazin-yl]pyrimidine ligand and two Cl atoms. The geometry around the Cu(II) atom is distorted square-pyramidal. The mol-ecules pack in the crystal structure via O-H⋯Cl, O-H⋯N, C-H⋯Cl and C-H⋯O hydrogen bonds, C-H⋯π ...

The bis(imino)pyridine scaffold provides support for the synthesis and characterization of unique Ag(I) pincer complexes [{ArN=CPh}(2)(NPh)]Ag(+)(OTf)(-) (Ar = 2,5-(t)Bu(2)C(6)H(3)3; 2,6-(i)Pr(2)C(6)H(3) 4). The bonding interactions between the cation-anion and between the bis(imino)pyridine ligand and the Ag centre are presented. Coordination of pyridine, toluene, 2-butyne and cyclooctene to t...

In the title compound, C(12)H(11)N(2) (+)·I(-), the aromatic rings are oriented at a dihedral angle of 73.40 (3)°. In the crystal structure, π-π contacts between the pyridine rings and the benzene and pyridine rings [centroid-centroid distances = 3.548 (3) and 4.211 (3) Å] may stabilize the structure.
