In the title compound, {[Ag(C(12)H(11)N(3)O)]NO(3)·H(2)O}(n), the Ag atom is coordinated by two N atoms from the heterocyclic ligand, giving a linear polycationic chain. Two long Ag⋯O(nitrate) inter-actions [2.667 (3) and 2.840 (3) Å] result in a three-dimensional network. The water mol-ecule consolidates the network structure by forming hydrogen bonds, one to the polycationic chain and one to ...

In the title compound, C(13)H(14)N(2)OS, the heterocyclic ring adopts a flattened boat conformation with the plane through the four coplanar atoms making a dihedral angle of 86.90 (13)° with the phenyl ring, which adopts an axial orientation. The thionyl, acetyl and methyl groups all have equatorial orientations. Inter-molecular N-H⋯O, N-H⋯S and C-H⋯O hydrogen bonds are found in the crystal str...

In the title compound, C(18)H(16)N(4)O(2), the plane defined by the ethyl C atoms and the attached N atom is inclined to the adjacent pyridine ring at an angle of 67.87 (16)°.

A new series of quinoline derivatives incorporated to glycosides and biologically active heterocyclic moieties were synthesized starting with 6-bromo-4-hydroxyquinaldine (6-bromo-4-hydroxy-2-methylquinoline) compound 1. Some of the synthesized compounds were evaluated for their antibacterial and antifungal activities. Most of the tested compounds exhibited potential antibacterial activity again...

In the mol-ecule of the title compound, C(14)H(10)FN(3)O, the bicyclic quinazoline system is effectively planar, with a mean deviation from planarity of 0.0140 (3) Å. The quinazoline heterocyclic system and the adjacent benzene ring make a dihedral angle of 85.73 (9)°. Two inter-molecular N-H⋯N hydrogen bonds contribute to the stability of the crystal structure. In addition, a weak π-π stacking...

The title compound, C(17)H(14)N(2)O(2)S, crystallizes with two roughly planar mol-ecules in the asymmetric unit, in which the dihedral angles between the 1,3-benzodioxole-5-carbaldehyde moiety and the heterocyclic five-membered ring are 3.76 (5) and 5.33 (12)°. In each mol-ecule, a short C-H⋯S contact generates an S(5) ring. In the crystal, pairs of mol-ecules are linked by a weak C-H⋯N inter-a...

In the title compound, C(15)H(12)ClNO(2), the two benzene rings are nearly perpendicular to each other [dihedral angle = 89.99 (13)°]. The O atom of the six-membered heterocyclic ring is disordered over two sites in a ratio of 0.46 (4):0.54 (4) and is displaced from the mean plane formed by other five atoms, resulting an envelope conformation of the six-membered hetercycle ring.

The title compound, C(15)H(23)NO(2)S, synthesized by N-methyl-ation of cyclo-hexyl-amine sulfonamide with propyl iodide, is of inter-est as a precursor to biologically active sulfur-containing heterocyclic compounds. The cyclo-hexyl ring exists in the chair form and the dihedral angle between the ring plane of the benzene ring and that of the cyclo-hexyl ring is 50.13 (9)°.

In the title compound, C16H17NO4S, the heterocyclic ring is almost planar (r.m.s. deviation = 0.007Å) and the dihedral angle between the benzene rings is 28.18 (10)°. The N-C-C-C torsion angle for the central chain is 62.4 (3)°: overall, the mol-ecule has a Z-shape. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R 2 (2)(8) loops.

In the title compound, C(29)H(42)N(2)O(2), the heterocyclic ring has a twist conformation. The cyclohexane ring adopts a chair conformation. The dihedral angle between the aromatic rings is 32.74 (6)°. The mol-ecular conformation is stabilized by two intramolecular O-H⋯N hydrogen bonds with graph-set motif S(6). The crystal packing is stabilized by C-H⋯O and C-H⋯π inter-actions.
