Conformational behaviors of trans-2,3-bis(methylthio)-1,4-dioxane, -dithiane and –diselenane. A hybrid-DFT study and NBO interpretations
The conformational behaviors of 2,3-bis(methylthio)-1,4-dioxane (1), 2,3-bis(methylthio)-1,4-dithiane (2) and 2,3-bis(methylthio)-1,4-diselenane (3) have been analyzed by means ofhybrid-density functional theory (B3LYP/Def2-TZVPP) based method and NBO interpretation.B3LYP/Def2-TZVPP results showed that the axial conformations of compounds 1-3 are morestable than their equatorial conformations. ...
متن کامل(E)-2,3-Bis[(E)-benzylideneamino]but-2-enedinitrile
The asymmetric unit of the title compound, C(18)H(12)N(4), consists of a half-mol-ecule, where the two halves of the mol-ecule are related by inversion symmetry. The mol-ecule is effectively planar, with the largest deviation from the 22-atom mean plane, measuring 0.024 (2) Å, exhibited by the ortho-C atom of the phenyl ring. The crystal structure exhibits π-stacking, with an inter-planar spaci...
متن کاملPhotochromic one-dimensional nanostructures based on dithienylethene: fabrication by light-induced precipitation and reversible transformation in the nanoparticle state.
A convenient protocol has been developed to fabricate one-dimensional nanostructures of a photochromic molecule cis-l,2-dicyano-l,2-bis(2,4,5-trimethyl-3-thieny1)ethene (CMTE). Light-induced self-assembled nanorods and nanowires of the colored form were obtained in situ under UV light irradiation in aqueous dispersion and redissolved under green light. Reversible and fatigue-resistant optical s...

The mol-ecular structure of the title compound, [WCl(2)(NO)(2)(C(21)H(24)N(2))(2)]·C(4)D(8)O, displays a distorted octa-hedral arrangement around the W atom with two trans 1,3-bis-(2,4,6-trimethyl-phen-yl)imidazol-2-yl-idene (IMes) carbene ligands in axial positions. The four equatorial positions are occupied by nitrosyl and chloride ligands, which are trans to each other. The C(carbene)-W-C(ca...
