N,N′-Bis(pyrazin-2-ylmethyl)pyrazine-2,3-dicarboxamide

Abstract

The title compound, C16H14N8O2, was prepared by a condensation reaction between the dimethyl ester of pyrazine-2,3-dicarboxylic acid and an excess of 2-(aminomethyl)pyrazine. The molecule is approximately V-shaped with the central pyrazine ring joined through amide linkages to two pyrazin-2-ylmethyl substituents. In the crystal, molecules are linked by N—H...O, N—H...N and C—H...O hydrogen bonds, forming a three-dimensional framework.
