Abstract

The crystal and molecular structures of (A) 3,5-Diacetyl-2,6-dimethyl-4-(3′-nitrophenyl)-1,4-dihydropyridine, (B) 3,5-Dibenzoyl-2,6-dimethyl-4-(3′-nitrophenyl)-1,4-di hydropyridine and (C) 3,5-Dicarbomethoxy-2,6-dimethyl-4-(4′-methylthiophenyl)-1,4-dihydropyridine derivatives were determined by X-ray diffraction methods. The compound (A), C17H18N2O4, crystallises in the monoclinic space group P21/n with a = 7.537(3) Å, b = 16.273(3) Å, c = 12.474(4) Å, β = 92.60(3)°, V = 1528.4(8) Å3, Z = 4, D calc = 1.3661 Mg/m3, μ = 0.812 mm-1, F 000 = 664, CuKα = 1.5406 Å and R = 0.0956. The compound (B), C27H22N2O4, crystallises in the monoclinic space group P21/c with a = 7.3113(7) Å, b = 23.3925(7) Å, c = 13.0737(7) Å, β = 91.31(7)°, V = 2235(3) Å3, Z = 4, D calc = 1.303 Mg/m3, μ = 0.176 mm-1, F 000 = 920, CuKα = 1.5406 Å and R = 0.0768. The compound (C), C18H21NO4S, crystallises in the orthorhombic space group Pnca with a = 13.205(3) Å, b = 26.558(3) Å, c = 10.244(3) Å, α = 90°, β = 90°, γ = 90°, V = 3592.6(12) Å3, Z = 8, D calc = 1.521 Mg/m3, μ = 2.050 mm-1, F 000 = 1728, CuKα = 1.5406 Å and R = 0.0535.
