N,N'-Bis(2-quinolylcarbon-yl)hydrazine.

ABSTRACT

The title compound, C(20)H(14)N(4)O(2), crystallizes in the ortho-rhom-bic system with a crystallographic twofold axis through the N-N bond. The mol-ecule is non-planar and the dihedral angle between two amide groups is 74.9 (2)°. An intra-molecular N-H⋯N hydrogen bond is present. In the crystal, the mol-ecules are packed in chains running along the c axis through inter-molecular N-H⋯O hydrogen bonds. These chains are further stabilized by inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions leading to the formation of a three-dimensional network.
