N-(1-Acryloyl-2,2,6,6-tetra-methyl-piperidin-4-yl)acryl-amide.

ABSTRACT: The title compound, C(15)H(24)N(2)O(2), crystallizes with two unique mol-ecules, (I) and (II), in the asymmetric unit, differing in the orientation of the acryloyl units with respect to the piperidine rings. The acryl-amide units are essentially planar in both mol-ecules (r.m.s. deviations = 0.042 and 0.024?Å, respectively), as are the C(3)N chains of the acryloyl units. The carbonyl O atoms of the acryloyl systems lie significantly out of these planes, viz. by -0.171?(9)?Å for molecule (I) and by 0.33?(1)?Å for molecule (II). The acryl-amide and acryloyl planes are inclined at 68.7?(4)° and 59.8?(3)° in the two mol-ecules. The piperidine rings each adopt twist boat conformations. In the crystal, strong N-H?O hydrogen bonds link the mol-ecules into zigzag C(4) chains along b. Additional C-H?O contacts result in the formation of stacks along a.

Project description:In the title hydrate, C16H23BrN2O·2H2O, the organic mol-ecule features a strong intra-molecular O-H?N hydrogen bond. The piperidine ring, in addition, adopts a chair conformation with the exocyclic C-N bond in an equatorial orientation. The water molecules of crystallization are disordered (each over two sets of sites with half occupancy. In the crystal, they associate into corrugated (100) sheets of (H2O)4 tetra-mers linked by O-H?O hydrogen bonds. The organic mol-ecules, in turn, are arranged at both sides of these sheets, linked by water-piperidine O-H?N hydrogen bonds.

2,2,6,6-Tetra-kis(biphenyl-2-yl)-4,4,8,8-tetra-methyl-cyclo-tetra-siloxane.

Project description:The title compound, [-Si(C(12)H(9))(2)OSi(CH(3))(2)O-](2), was obtained unintentionally as the product of an attempted crystallization of caesium bis-(biphenyl-2,2'-di-yl)fluoro-silicate from dimethyl-formamide. In the crystal, the mol-ecule is located on an inversion center and the siloxane ring adopts a twist-chair conformation with the two dimethyl-substituted Si atoms lying 0.7081 (5) Å out of the plane defined by the two bis-(biphenyl-2-yl)-substituted Si atoms and the four O atoms. In each Si(C(12)H(9))(2) unit, the orientation of one terminal phenyl ring relative to the phenyl-ene ring of the other biphenyl moiety suggests a parallel displaced π-π stacking inter-action [centroid distance = 4.2377 (11) Å and dihedral angle = 15.40 (9)°].

Comparison of the crystal structures of 4,4'-bis-[3-(4-methyl-piperidin-1-yl)prop-1-yn-1-yl]-1,1'-biphenyl and 4,4'-bis-[3-(2,2,6,6-tetra-methyl-piperidin-1-yl)prop-1-yn-1-yl]-1,1'-biphen-yl.

Project description:As part of a comprehensive program to discover ?9?10 nicotinic acetyl-choline receptor antagonists, the title compounds C30H36N2, (I), and C36H48N2, (II), were synthesized by coupling 4,4'-bis-(3-bromo-prop-1-yn-1-yl)-1,1'-biphenyl with 4-methyl-piperidine and 2,2,6,6-tetra-methyl-piperidine, respectively, in aceto-nitrile at room temperature. In compound (I), the biphenyl system has a twisted conformation with a dihedral angle of 26.57?(6)° between the two phenyl rings of the biphenyl moiety, while in compound (II), the biphenyl moiety sits on a crystallographic inversion centre so the two phenyl rings are exactly coplanar. The terminal piperidine rings in both compound (I) and compound (II) are in the chair conformation. In compound (I), the dihedral angles about the ethynyl groups between the planes of the phenyl rings and the piperidine ring N atoms are 37.16?(16) and 14.20?(17)°. In compound (II), the corresponding dihedral angles are both 61.48?(17)°. There are no noteworthy inter-molecular inter-actions in (I), but in (II) there is a small ?-overlap between inversion-related mol-ecules (1 - x, 1 - y, 1 - z), with an inter-planar spacing of 3.553?(3)?Å and centroid-to-centroid separation of 3.859?(4)?Å.

Crystal structure of 4-({5-[(E)-(3,5-di-fluoro-phen-yl)diazen-yl]-2-hy-droxy-benzyl-idene}amino)-2,2,6,6-tetra-methyl-piperidin-1-ox-yl.

Project description:The asymmetric unit of the title compound, C22H25F2N4O2, contains two crystallographically independent mol-ecules. In one mol-ecule, the two benzene rings are oriented at a dihedral angle of 1.93 (10)° and in the other mol-ecule the corresponding dihedral angle is 7.19 (9)°. The piperidine rings in the two mol-ecules adopt a similar distorted chair conformation, and both have pseudo-mirror planes passing through the N-O bonds. An intra-molecular O-H⋯N hydrogen bond between the hy-droxy group and the imine N atom is observed in both mol-ecules. In the crystal, weak C-H⋯O and C-H⋯F hydrogen bonds, enclosing R 2 (2)(6) ring motifs, and weak π-π stacking inter-actions link the mol-ecules into a three-dimensional supra-molecular network, with centroid-to-centroid distances between the nearly parallel phenyl and benzene rings of adjacent mol-ecules of 3.975 (2) and 3.782 (2) Å.

Crystal structures of (E)-3-(furan-2-yl)-2-phenyl-N-tosyl-acryl-amide and (E)-3-phenyl-2-(m-tol-yl)-N-tosyl-acryl-amide.

Project description:In the title N-tosyl-acryl-amide compounds, C20H17NO4S, (I), and C23H21NO3S, (II), the conformation about the C=C bond is E. The acryl-amide groups, [-NH-C(=O)-C=C-], are almost planar, with the N-C-C=C torsion angle being -170.18?(14)° in (I) and -168.01?(17)° in (II). In (I), the furan, phenyl and 4-methyl-benzene rings are inclined to the acryl-amide mean plane by 26.47?(11), 69.01?(8) and 82.49?(9)°, respectively. In (II), the phenyl, 3-methyl-benzene and 4-methyl-benzene rings are inclined to the acryl-amide mean plane by 11.61?(10), 78.44?(10) and 78.24?(10)°, respectively. There is an intra-molecular C-H?? inter-action present in compound (II). In the crystals of both compounds, mol-ecules are linked by pairs of N-H?O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif. In (I), the dimers are reinforced by C-H?O hydrogen bonds and linked by C-H?? inter-actions, forming chains along [011]. In the crystal of (II), the dimers are linked via C-H?O hydrogen bonds, forming chains along [100]. The chains are further linked by C-H?? inter-actions, forming layers parallel to (010).
