N,N′-Bis(pyridin-3-yl)oxamide

Abstract

Key indicators: single-crystal X-ray study; T = 297 K; mean (C-C) = 0.002 Å; R factor = 0.043; wR factor = 0.126; data-to-parameter ratio = 12.8.The title molecule, C 12 H 10 N 4 O 2 , located about an inversion centre, is roughly planar, with an r.m.s. deviation from the least-squares plane of all non-H atoms of 0.019 Å . In the crystal, N-HÁ Á ÁN hydrogen bonds between the amide N-H group and the pyridine N atom connect the molecules into a corrugated layer parallel to (101).
