3-(2-Ethoxyphenyl)-1-(3-nitrophenyl)triaz-1-ene
The title compound, C(14)H(14)N(4)O(3), exhibits a trans geometry about the N=N double bond in the triazene unit. The mol-ecule is approximately planar (r.m.s. deviation = 0.044 Å for all non-H atoms). An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, C-H⋯N hydrogen bonds lead to the formation of dimers which are, in turn, connected to each other by C-H⋯O hydrogen bonds, forming in...
متن کامل1-[5-(3-Chlorophenyl)-2-methyl-3-thienyl]-3,3,4,4,5,5-hexafluoro-2-(2-methoxyphenyl)cyclopent-1-ene
The title compound, C(23)H(15)ClF(6)OS, has thienyl and phenyl-ene substituents on the double-bond C atoms of the envelope-shaped cyclo-pentenyl ring. The aromatic systems are aligned at 55.3 (4) (thien-yl) and 60.8 (7)° (phenyl-ene) with respect to the planar C-C=C-C portion of the main central cyclo-pentenyl ring.
متن کامل1-(3,5-Dichlorophenyl)-3-(2-methoxyphenyl)triaz-1-ene
The title mol-ecule, C(13)H(11)Cl(2)N(3)O, is almost planar and adopts a trans conformation with respect to the -N=N- bond; the dihedral angle between the rings is 3.47 (2)°. The N-N bond lengths indicate the presence of single- and double-bond characters and hence the -N=N-NH- moiety. In the crystal, inversion dimers linked by pairs of N-H⋯Cl hydrogen bonds occur, and C-H⋯π and π-π stacking in...

A novel compound involved in the aroma of the fruit Campomanesia lineatifolia was isolated; the structure was determined by spectroscopic methods, mainly 1D and 2D NMR.
متن کاملAb Initio Study of Conformational and Configurational Properties of 1, 3- Diazacyclohepta-1, 2-diene and 1, 3-Diazacycloocta-1, 2-diene
Ab initio calculations at HF/6-31G* level of theory for geometry optimization and MP2/6-31G*//HF/6-31G* for a single point total energy calculation are reported for the importantenergy-minimum conformations and transition-state geometries of 1, 3-diazacyclohepta-1, 2-diene (2) and 1, 3-diazacycloocta-1, 2-diene (3). The C2 symmetric twist-chair (2-TC)conformation of 2 is calculated to be 7.4 kJ...
