1,1'-[4-(2,4-Dichloro-phen-yl)-2,6-di-methyl-1,4-di-hydro-pyridine-3,5-di-yl]diethanone.

ABSTRACT: In the title compound, C(17)H(17)Cl(2)NO(2), the central 1,4-dihydro-pyridine ring adopts a flattened-boat conformation. The ethanone substituents of the dihydro-pyridine ring at positions 3 and 5 have synperiplanar (cis) or anti-periplanar (trans) conformations with respect to the adjacent C=C bonds in the dihydro-pyridine ring. The 2,4-dichloro-phenyl ring is almost planar [r.m.s. deviation = 0.0045?(1)?Å] and almost perpendicular [89.27?(3)°] to the mean plane of the dihydro-pyridine ring. In the crystal, an N-H?O hydrogen bond links mol-ecules into a zigzag chain along the ac diagonal. C-H?Cl contacts form centrosymmetric dimers and additional weak C-H?O contacts further consolidate the packing.
