N,N′-Bis(pyrazin-2-ylmeth-yl)pyrazine-2,3-dicarb-oxamide

摘要

The title compound, C16H14N8O2, was prepared by a condensation reaction between the dimethyl ester of pyrazine-2,3-di-carb-oxy-lic acid and an excess of 2-(amino-meth-yl)pyrazine. The mol-ecule 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.
