(3E,5E)-3,5-Bis(4-methylbenzylidene)-1-[3-(piperidin-1-yl)propanoyl]piperidin-4-one
In the title compound, C(29)H(34)N(2)O(2), the central piperidine ring adopts a half-chair conformation, whereas the terminal one adopts a chair conformation. The mean plane of the central piperidine ring [maximum deviation = 0.384 (2) Å] makes dihedral angles of 64.82 (13) and 17.55 (13)° with the benzene rings. In the crystal, mol-ecules are linked into a tape along the b axis via C-H⋯O inter...

In the title compound, C(22)H(27)NO(3), the piperidine ring adopts a slightly distorted chair conformation. The dihedral angle between the two aromatic rings is 60.4 (1)°. In the crystal, the amino group forms a rather long N-H⋯O contact to a methoxy O atom. There are also C-H⋯O interactions present.
متن کامل1-Benzyl-3,5-bis(4-chlorobenzylidene)piperidin-4-one
The title compound, C(26)H(21)Cl(2)NO, crystallizes with two symmetry-independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules, the central heterocyclic ring adopts a sofa conformation. The dihedral angles between the planar part of this central heterocyclic ring [maximum deviations of 0.011 (1) and 0.036 (1) Å in mol-ecules A and B, respectively] and the two almost planar [m...
متن کامل1-Methyl-3,3-bis[(4-methylphenyl)sulfanyl]piperidin-2-one
The piperidone ring in the title compound, C(20)H(23)NOS(2), has a half-chair distorted to a twisted-boat conformation [Q(T) = 0.5200 (17) Å]. One of the S-bound benzene rings is almost perpendicular to the least-squares plane through the piperidone ring, whereas the other is not [dihedral angles = 75.28 (5) and 46.41 (5) Å, respectively]. In the crystal, the presence of C-H⋯O and C-H⋯π inter-a...
متن کامل(3E,5E)-3,5-Bis(naphthalen-1-ylmethylidene)piperidin-4-one
In the title compound, C(27)H(21)NO, the piperidine ring adopts a chair conformation. The mean plane through the piperidine ring makes dihedral angles of 49.27 (5) and 63.07 (5)° with the naphthalene ring systems. In the crystal, mol-ecules are linked into dimers via pairs of inter-molecular C-H⋯O inter-actions, generating ten-membered R(2) (2)(10) ring motifs. C-H⋯π inter-actions further stabi...
