Abstract:
Title compound is triclinic, M r = 461.60; P 1, a = 9.158(1), b = 16.062(3), c = 19.472(3) Å, α = 110.69(1)°, β = 89.70(1)°, γ = 103.17(1)°, V = 2 600(1) Å 3 , Z = 4, D o = 1.15(3), D c = 1.179(1) Mg m -3 , λ(CuK α ) = 1.5418 Å, μ = 0.509 mm -1 , F (000) = 976 K, R = 0.040 for 8 059 unique observed reflections. Both symmetrically independent molecules show a different geometry of the 1,4-dihydropyridine ring: either the boat conformation with apexes C( sp 3 ), N and boat angles 14.7(3)° and 10.3(2)° respectively, or the planar conformation. The conformation has been compared with similar dihydropyridines obtained from Cambridge Structural Database.
