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.

Diethyl 4-(biphenyl-4-yl)-2,6-dimethyl-1,4-di-hydro-pyridine-3,5-di-carboxyl-ate.

Project description:The title compound, C25H27NO4, has a flattened di-hydro-pyridine ring. The benzene and phenyl rings are synclinal to one another, forming a dihedral angle of 49.82?(8)°; the axis of the biphenyl rings makes an 81.05?(9)° angle to the plane of the di-hydro-pyridine ring. In the crystal, N-H?O hydrogen bonds link the mol-ecules into chain motifs running along the a-axis direction. The chains are cross-linked by C-H?O inter-actions, forming sheet motifs running slightly off the (110) plane, together with an intermolecular interaction between head-to tail biphenyl groups, thus making the whole crystal packing a three-dimensional network. Intra-molecular C-H?O hydrogen bonds are also observed.

Diethyl 4-(2-meth-oxy-phen-yl)-2,6-di-methyl-1,4-di-hydro-pyridine-3,5-di-carboxyl-ate.

Project description:In the title compound, C20H25NO5, the di-hydro-pyridine ring adopts a flattened boat conformation. The meth-oxy-phenyl ring is almost perpendicular to the mean plane of the pyridine ring [dihedral angle = 88.42?(3)°]. The two carbonyl units adopt a synperiplanar conformation with respect to the double bonds in the di-hydro-pyridine ring. In the crystal, mol-ecules are connected by N-H?O hydrogen bonds into R 4 (4)(24) tetra-meric rings. A region of disordered electron density, located at the center of four adjacent mol-ecules, was treated with the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]. It is probably the result of traces of the solvent of crystallization and was not taken into account during the structure refinement.

Synthesis, crystal structure and Hirshfeld surface analysis of diethyl 2,6-dimethyl-4-(thio-phen-3-yl)-1,4-di-hydro-pyridine-3,5-di-carboxyl-ate.

Project description:In the title compound, C17H21NO4S, the 1,4-di-hydro-pyridine ring has an envelope conformation with the Csp 3 atom at the flap. The thio-phene ring is nearly perpendicular to the best plane through the 1,4-di-hydro-pyridine ring, the dihedral angle being 82.19 (13)°. In the crystal, chains running along the b-axis direction are formed through N-H⋯O inter-actions between the 1,4-di-hydro-pyridine N atom and one of the O atoms of the ester groups. Neighbouring chains are linked by C-H⋯O and C-H⋯π inter-actions. A Hirshfeld surface analysis shows that the most prominent contributuion to the surface contacts are H⋯H contacts (55.1%).
