Abstract

© Eya'ane Meva et al. 2017. The crystal structures of N,-Aminopyridine-2-carboximidamide (C 6 H 8 N 4 ), 1, and N,-{[1-(pyridin-2-yl)ethylidene]amino}pyridine-2-carboximidamide (C 13 H 13 N 5 ), 2, are described. The non-H atoms in compound 1 are nearly planar (r.m.s. deviation from planarity = 0.0108 Å ), while 2 is twisted about the central N-N bond by 17.8 (2)-. Both molecules are linked by intermolecular N-H·N hydrogen-bonding interactions; 1 forms a two-dimensional hydrogen-bonding network and for 2 the network is a one-dimensional chain. The bond lengths of these molecules are similar to those in other literature reports of azine and diimine systems.
