Crystal structure of the diglycidyl ether of eugenol

2017

The diep­oxy monomer (DGE-Eu) was synthesized from eugenol by a three-step reaction. It consists of a 1,2,4-tris­ubstituted benzene ring substituted by diglycidyl ether, a meth­oxy group and a methyl­oxirane group. The three-membered oxirane rings are inclined to the benzene ring by 61.0 (3) and 27.9 (3)°. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming layers parallel to the ab plane.

Crystal structure of bis{μ2-3-(pyridin-2-yl)-5-[(1,2,4-triazol-1-yl)methyl]-1,2,4-triazolato}bis[aquanitratocopper(II)] dihydrate

2016

The title complex is a centrosymmetric dimer with a copper–copper distance of 4.0408 (3) Å. The Cu ions in the dimer are bridged by two triazole rings and oxygen donor ligands from water mol­ecules and nitrate anions in a distorted octa­hedral coordination geometry.

Crystal structure of 4-(4-chlorophenyl)-6-(morpholin-4-yl)pyridazin-3(2H)-one

2015

In the crystal, pairs of centrosymmetrically related mol­ecules are linked into dimers via N—H⋯O hydrogen bonds, forming (8) ring motifs. The dimers are connected via C—H⋯O and C—H⋯Cl hydrogen bonds, forming a three-dimensional network·Semi-empirical mol­ecular orbital calculations were carried out using the AM1 method.
