Crystal structures of N'-amino-pyridine-2-carboximidamide and N'-{[1-(pyridin-2-yl)ethyl-idene]amino}-pyridine-2-carboximidamide.

ABSTRACT: The crystal structures of N'-amino-pyridine-2-carboximidamide (C₆H₈N₄), 1, and N'-{[1-(pyridin-2-yl)ethyl-idene]amino}-pyridine-2-carboximidamide (C₁₃H₁₃N₅), 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 mol-ecules are linked by inter-molecular N-H⋯N hydrogen-bonding inter-actions; 1 forms a two-dimensional hydrogen-bonding network and for 2 the network is a one-dimensional chain. The bond lengths of these mol-ecules are similar to those in other literature reports of azine and di-imine systems.
