The mol-ecule of the title compound, C(18)H(17)N(7)S, is non-planar, with a dihedral angle of 71.4 (4)° between the two triazole rings, and an angle of 15.5 (3)° between the two phenyl rings. An intra-molecular N-H⋯S hydrogen bond forms a five-membered ring.

In the title compound, C(12)H(10)N(2)O(4)S, the conformation of the N-H bond in the -SO(2)-NH- fragment is syn to the ortho-nitro group in the sulfonyl-benzene ring. The mol-ecule is twisted at the S-N bond, the C-N-S-C torsion angle being -72.83 (15)°. The dihedral angle between the benzene rings is 59.55 (7)°. The amide H atom and the nitro group O atom form an intra-molecular hydrogen bond, ...

The title compound, C(18)H(18)O(4)S(2), was synthesized by the reaction of 1,2-dibromo-ethane with methyl thio-salicylate. The complete molecule is generated by crystallographic twofold symmetry: two methyl benzoate units are linked by an -S-(CH(2))(2)-S- bridging chain with a gauche S-CH(2)-CH(2)-S torsion angle [72.88 (16)°]. The two aromatic rings form a dihedral angle of 79.99 (6)°. In the ...

In the mol-ecular structure of the title compound, [NiCl2(C7H12N2S)2], the Ni(II) atom has a distorted tetra-hedral geometry, coordinated by two Cl atoms [Ni-Cl= 2.2336 (6) Å] and two thione S atoms [Ni-S= 2.3024 (6) Å]. The angles at the Ni(II) cation, which lies on a twofold rotation axis, are Cl-Ni-Cl = 115.58 (3)° and S-Ni-S = 94.55 (3)°. All other angles at the central Ni(II) atom range fr...

OBJECTIVE To determine the risk for late epilepsy (>2 weeks postoperatively) following aneurysmal subarachnoid haemorrhage (SAH) treated by early aneurysm clipping. DESIGN Subgroup analysis of the East Anglian regional audit of SAH (1994-2000; n = 872) with 12 month follow up. Prophylactic anticonvulsants were not routinely prescribed unless there was a perioperative seizure. SUBJECTS 472 p...

purpose: to compare anterior segment and ocular biometric parameters of unaffected fellow eyes of patients with a previous attack of acute angle closure (aac), primary angle closure suspect (pacs) eyes, and normal eyes; and to assess the risk of developing aac in pacs. methods: in this prospective comparative observational case series, 16 unaffected fellow eyes of patients with a previous attac...
