- Abstract
We have previously published on a new triazolic phosphonic α-amino ester in position 4 on the triazole ring of a naphthalene ester. The aim of the present paper was to describe its crystallographic study by XRD. The crystal structure of naphthalen-2-yl 1-(benzamido(diethoxyphosphoryl)methyl)-1H-1,2,3-triazole-4-carboxylate was determined by single-crystal X-ray diffraction. This compound crystallizes in the monoclinic system, space group P21/c. The naphthalene system is almost planar and makes dihedral angles of 67.1(2)° and 63.9(2)° with the triazole ring and the phenyl cycle, respectively. The phosphorus atom is surrounded by three oxygen atoms and one carbon atom building a distorted tetrahedron. It is also noted, that one of the two ethyl groups is disordered. In the crystal, the molecules are connected through C-H...O and N-H...O hydrogen bonds to build dimers that are linked together by C-H...O hydrogen bonds, in addition to C-H...π interactions. The presence of an intramolecular hydrogen bond contributes to the stability of the molecular conformation by completing the S(5) cycle.
