Inter­molecular hydrogen bonding in N-methyl-N′-(pyridin-2-yl)benzene-1,2-di­amine

The structure of N-methyl-N′-(pyridin-2-yl)benzene-1,2-di­amine, C(12)H(13)N(3), at 123 K has ortho­rhom­bic (Pna2(1)) symmetry. The title compound displays an unexpected proton-splitting pattern when studied by (1)H NMR spectroscopy. The X-ray crystallography analysis determined this to be caused b...

Sumario:The structure of N-methyl-N′-(pyridin-2-yl)benzene-1,2-di­amine, C(12)H(13)N(3), at 123 K has ortho­rhom­bic (Pna2(1)) symmetry. The title compound displays an unexpected proton-splitting pattern when studied by (1)H NMR spectroscopy. The X-ray crystallography analysis determined this to be caused by strong dual N—H⋯N hydrogen bonding.
