N-(Pyridin-2-ylmethyl)pyridin-2-amine [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2011
The title compound, C(11)H(11)N(3), crystallizes with two mol-ecules (A and B) in the asymmetric unit. The geometries of both mol-ecules are very similar, with the exception of the torsion angles of the inter-ring chains; the values for C-N-C-C are 67.4 (5) and -69.3 (5)° for mol-ecules A and B, respectively.
