title: Nifedipine-pyrazine (2/1).
abstract: In the title compound, 2C(17)H(18)N(2)O(6)·C(4)H(4)N(2) [systematic name: 3,5-dimethyl 2,6-dimethyl-4-(2-nitro-phen-yl)-1,4-di-hydro-pyridine-3,5-dicarboxyl-ate-pyrazine (2/1)], the complete pyrazine molecule is generated by crystallographic inversion symmetry. The center of the pyrazine ring lies on an inversion center. The nifedipine mol-ecules are linked into chains along the c axis through N-H⋯O hydrogen bonds, while the pyrazine mol-ecules are organized in the structure through van der Waals inter-actions.
