In the title compound, C(13)H(9)Cl(2)NO(3)S·H(2)O, the conformation of the C=O bond is syn to the meta-Cl group in the benzoyl ring. The mol-ecules are twisted at the S-N bond with a C-S-N-C torsion angle of 72.9 (2)°. The dihedral angle between the sulfonyl benzene ring and the S-NH-C-O segment is 77.8 (1)° and that between the sulfonyl and benzoyl benzene rings is 80.5 (1)°. In the crystal, m...

In the title compound, C(27)H(27)Cl(2)N(7)O(4)S, the amide groups bearing the N-S group and the tert-butyl group have s-trans conformations. The steric size of the tert-butyl and [(6-chloro-3-pyrid-yl)meth-yl]imidazolidin-2-yl-idene groups cause the 2-chloro-benzoyl group and the benzyol group to be directed away from one another, forming a dihedral angle of 60.62 (17)°. The central N-N bond ad...

In the title mol-ecule, C(4)H(6)N(8)S(2), two tetra-zole rings linked by a disulfide bridge form a dihedral angle of 71.32 (7)° [C-S-S-C torsion angle = -80.51 (10)°]. In the crystal, strong inter-molecular π-π inter-actions between the tetra-zole rings [centroid-centroid distance = 3.285 (3) Å] link pairs of mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H⋯N hydrogen bonds furt...

In the title compound, C(13)H(9)Cl(2)NO(3)S, the conformation of the N-H bond in the C-SO(2)-NH-C(O) segment is anti to the C=O bond. The mol-ecule is twisted at the S atom with a torsion angle of 67.5 (3)°. The dihedral angle between the sulfonyl benzene ring and the -SO(2)-NH-C-O segment is 79.0 (1)° and that between the sulfonyl and benzoyl benzene rings is 85.6 (1)°. In the crystal, mol-ecu...

In this paper we studied preparation of working films of dye-sensitized solar cells using screen printed method. The organic dye based on phenoltiazine with cyanoacrylic acid as the electron donor group utilized as photosensitizer. Fluorine-doped thin oxide FTO coated glass is transparent electrically conductive and ideal for use in dye-sensitized solar cells. FTO glass was coated by screen pri...

PURPOSE The purpose of this study was to propose mathematical models for predicting mandibular growth direction and amount in children with normal skeletal relationship from 4 to 9 years of age using the craniofacial characteristics found on the head films. METHODS Lateral cephalograms of 27 Japanese children with normal occlusion at 4 (T1) and 9 (T2) years of age were traced and measured. Fi...

PURPOSE To evaluate retinal nerve fiber layer (RNFL) thickness profiles according to the foveal position relative to the optic disc in myopia METHODS In 164 eyes of 164 healthy myopic subjects, the disc-foveal angle was defined as the angle between a horizontal line through the disc center and the line connecting the fovea and disc center in fundus photographs overlaid on Cirrus-HD optical co...

The structure and composition of 1,2-dimethoxy-3,3,4,4-tetrafluorocyclobut-1-ene (DMCB) have been measured by electron diffraction from the gas at a temperature of 370 K with the help of auxiliary data from molecular orbital and normal coordinate calculations, the former at several levels of theory and basis-set size, most importantly B3LYP/cc-pVTZ. The compound was found to exist primarily as ...

In the title compound, C(11)H(15)N(3)O(3)S, the C-S-N(H)-N linkage is nonplanar, the torsion angle being 75.70 (12)°. The compound has two almost planar fragments linked to the S atom: the hydrazone-derivative fragment [(HONC(4)H(6))N-N(H)-] and the tolyl fragment (C(7)H(7)-) have maximum deviations from the mean plane through the non-H atoms of 0.0260 (10) and 0.0148 (14) Å, respectively. The ...

In the title compound, C(14)H(12)N(2)O(5)S, the conformation between the N-H group and the ortho-nitro group in the sulfonyl benzene ring is syn and that between the C=O and meta-methyl groups in the benzoyl ring is anti. The mol-ecule is twisted at the S-N bond with a torsion angle of 64.3 (2)°. The dihedral angle between the sulfonyl benzene ring and the -SO(2)-NH-C-O segment is 75.73 (7)° an...
