In the crystal structure of the title compound, C(7)H(10)N(2)O(2)S, a benzoic acid derivative, inter-molecular N-H⋯O inter-actions link the mol-ecules into a three-dimensional network.
The crystal structure of the title adamantane derivative, C(12)H(18)O(3), has been determined by X-ray diffraction. The structure is stabilized by inter-molecular O-H⋯O hydrogen bonds, forming a chain.
A new derivative of Cyclotriphosphazene with xanthydrol as the oxygen-containing ligand was synthesized. Firstly Hexaclorocyclotriphosphazene was obtained Hexaclorocyclotriphosphazene from ammonium chloride and phosphorus pentachloride reaction and then the deprotonated xanthydrol was reacted with Hexaclorocyclotriphosphazene in the ratio of 6:1 in dry toluene as the solve...
In this study, a series of novel compounds based on 5-(5-nitrothiophene-2-yl)-1,3,4-thiadiazole possessing (het)aryl thio pendant at C-2 position of thiadiazole ring is developed and evaluated as antileishmanial agents using MTT colorimetric assay. 10 New compounds containing aryl and hetero aryl derivatives, started from thiophene-2-carbaldehyde in five steps, were synthesized in good to excel...

Chemical vapour deposition enables the polymerisation of N -unsubstituted diketopyrrolopyrrole derivative into polymer thin film combining H-bonding and conjugated covalent bonds, increasing conductivity lifetime electronically excited states.
In order to improve the approximation of spatial derivatives without meshes, a set of meshfree numerical schemes for derivative terms is developed, which is compatible with the coordinates of Cartesian, cylindrical, and spherical. Based on the comparisons between numerical and theoretical solutions, errors and convergences are assessed by a posteriori method, which shows that the approximations...
In the title chalcone derivative, C(20)H(22)O(6), the dihedral angle between the mean planes of the benzene rings is 15.77 (6)°. The H atoms of the central C=C double bond are in a trans configuration. There are a number of C-H⋯O interactions and a C-H⋯π interaction present in the crystal structure.
In the title compound, C(13)H(16)N(4)OS(3), a thienopyridine-derivative, the tetra-hydro-pyridine ring exhibits a half-chair conformation, and the folded conformation of the mol-ecule is defined by the N-C-C-N torsion angle of -78.85 (16)°. The crystal packing features inter-molecular C-H⋯N, N-H⋯N and C-H⋯O hydrogen bonds.
In the title hydrazone derivative, C(15)H(13)ClN(2)O(2), the dihedral angle between the benzene rings is 2.36 (2)°. An intra-molecular N-H⋯O hydrogen bond is present. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains running parallel to the b axis.
