4-[4-(Piperidin-1-yl)piperidin-1-yl]benzonitrile
In the title compound, C(17)H(23)N(3), both piperidine rings adopt chair conformations. In the crystal packing, intermolecular C-H⋯N hydrogen bonds and C-H⋯π interactions are present.
متن کاملCrystal structure of 1-(piperidin-1-yl)butane-1,3-dione
In the title compound, C9H15NO2, the piperidine ring exhibits a chair conformation. The butane-dione subunit exhibits a conformation with the ketone C atom in an eclipsed position with respect to the amide carbonyl group. In the crystal, a two-dimensional layered arrangement is formed by hydrogen bonds of the C-H⋯O type between the methyl group and the exocyclic methyl-ene unit as donor sites a...
متن کامل[(4E)-1-Methyl-2,6-diphenyl-3-(propan-2-yl)piperidin-4-ylidene]amino 3-methylbenzoate
In the title compound, C29H32N2O2, the piperidine ring exists in a chair conformation (the bond-angle sum at the sp (2)-hybridized C atom is 359.79°). The phenyl rings and the methyl group substituted on the heterocyclic ring are in equatorial orientations. In the crystal, pairs of C-H⋯π inter-actions result in the formation of inversion dimers.
متن کامل(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...
متن کاملMethyl 4-(piperidin-1-ylcarbonyl)benzoate
In the title compound, C(14)H(17)NO(3), the piperidine ring has a chair conformation and an intra-molecular C-H⋯O inter-action stabilizes the mol-ecular conformation. In the crystal, weak inter-molecular C-H⋯O inter-actions occur.
