The title compound, C8H12S2 (trivial name DTCDD), was obtained as a side product of the reaction between cis-1,4-di-chloro-but-2-ene and sodium sulfide. The asymmetric unit consists of one-quarter of the mol-ecule (S site symmetry 2) and the complete mol-ecule has 2/m (C 2h ) point symmetry with the C=C bond in an E conformation. The geometry of the title(More)
The crystal structure of the title compound, C(13)H(15)N(3)O(3) x C(3)H(7)NO, was determined as part of a larger project focusing on creatinine derivatives as potential pharmaceuticals. The molecule is essentially planar, in part because of intramolecular hydrogen bonding. Inversion-related pairs of molecules result from intermolecular hydrogen bonding. The(More)
The crystal structures of the title compounds, [Mo{(C4H8NO)2P(C2F5)}(CO)5], (1a), and [Mo{(C5H10N)2P(C2F5)}(CO)5], (2a), were determined as part of a larger project that focuses on the synthesis and coordination chemistry of phosphane ligands possessing moderate (electroneutral, i.e. neither electron-rich nor electron-deficient) electronic characteristics.(More)
The title mol-ecule, C8H12NO5PS2, exhibits a crystallographic mirror plane that is perpendicular to the ring and bis-ects the sulfamoyl and thio-phosphate ester groups. In the crystal, mol-ecules are linked by N-H⋯O hydrogen-bonding inter-actions reminiscent of carb-oxy-lic acid hydrogen bonding pairs, forming chains parallel to the b-axis direction.
The asymmetric unit of the title compound, [(CH(3))(2)NH(CH(2))(2)NH(CH(3))(2)][CoCl(4)], contains a tetra-chlorido-cobalt-ate(II) dianion and two halves of two centrosymmetric, crystallographically-independent, dications. One independent dication is disordered between two conformations in a 0.784 (13):0.216 (13) ratio. In the crystal, inter-molecular(More)
Structural studies performed in this laboratory of organophosphorus pesticides continue with these related compounds. The -NO2 groups of methyl parathion (systematic name: dimethyl 4-nitrophenyl phosphorothioate, C8H10NO5PS) and dicapthon (systematic name: 2-chloro-4-nitrophenyl dimethyl phosphorothioate, C8H9ClNO5PS) make dihedral angles of 10.67 (8) and(More)
The crystal structures of the title compounds, alternatively called 2,2'-(2,2'-biimidazole-1,1'-diyl)diacetohydrazide monohydrate, C(10)H(14)N(8)O(2).H(2)O, (I), and 3,3'-(2,2'-biimidazole-1,1'-diyl)dipropionohydrazide, C(12)H(18)N(8)O(2), (II), respectively, have been determined. The molecules consist of half-molecule asymmetric units related by a twofold(More)
In the title urea-based herbicide, C(9)H(10)BrClN(2)O(2), there exist multiple inter- and intra-molecular inter-actions. Most notably, the intra-molecular hydrogen bond between the urea carbonyl O atom and an aromatic H atom affects the planarity and torsion angles of the mol-ecule by restricting rotations about the Ar-secondary amine N and the secondary(More)
