Crystal structure of (E)-4-ethyl-2-(4-meth-oxy-benzyl-idene)-3,4-di-hydro-naphthalen-1(2H)-one.

ABSTRACT: In the title compound, C20H20O2, the exocyclic C=C double bond has an E conformation. The ethyl substituent on the cyclo-hexa-none ring is in an axial orientation. The cyclo-hexa-none ring adopts a screw-boat conformation, with the methyl-ene C atom and the C atom bearing the 4-meth-oxy-benzyl-idene group displaced from the other atoms by 0.812?(1) and 0.334?(1)?Å, respectively. The dihedral angle between the planes of the benzene rings is 42.20?(8)°. In the crystal, no directional inter-actions beyond van der Waals contacts are observed.

Project description:In the title compound C(22)H(24)O(2), the exocyclic C=C double bond is in an E configuration and the tert-butyl group is in an axial position on the cyclo-hexa-none ring. The cyclo-hexa-none ring in the dihydro-naphthalene fused-ring system adopts a half-chair conformation in both independent two mol-ecules in the asymetric unit.

(E)-N'-(3,4-Di-meth-oxy-benzyl-idene)nicotinohydrazide monohydrate.

Project description:In the title hydrated compound, C15H15N3O3·H2O, the nicotinohydrazide mol-ecule adopts a trans conformation with respect to the C=N double bond. The dihedral angle between the benzene and pyridine rings is 5.10?(14)°. In the crystal, the solvent water mol-ecule acts as an acceptor, forming an N-H?O hydrogen bond supported by two C-H?O contacts. It also acts as a donor, forming bifurcated O-H?(O,O) and O-H?N hydrogen bonds that combine with the former contacts to form zigzag chains of mol-ecules along the c-axis direction. An additional O-H?O donor contact completes a set of six hydrogen bonds to and from the water mol-ecule and connects it to a third nicotinohydrazide mol-ecule. This latter contact combines with weaker C-H?O hydrogen bonds supported by a C-H?? contact to stack mol-ecules along b in a three-dimensional network.

Crystal structure of (E)-2-[(2-bromopyridin-3-yl)methyl-idene]-6-meth-oxy-3,4-di-hydro-naphthalen-1(2H)-one and 3-[(E)-(6-meth-oxy-1-oxo-1,2,3,4-tetra-hydro-naphthalen-2-ylidene)meth-yl]pyridin-2(1H)-one.

Project description:The title compounds C17H14BrNO2, (I), and C17H15NO3, (II), were obtained from the reaction of 6-meth-oxy-3,4-di-hydro-2H-naphthalen-1-one and 2-bromo-nicotinaldehyde in ethanol. Compound (I) was the expected product and compound (II) was the oxidation product from air exposure. In the crystal structure of compound (I), there are no short contacts or hydrogen bonds. The structure does display π-π inter-actions between adjacent benzene rings and adjacent pyridyl rings. Compound (II) contains two independent mol-ecules, A and B, in the asymmetric unit; both are non-planar, the dihedral angles between the meth-oxy-benzene and 1H-pyridin-2-one mean planes being 35.07 (9)° in A and 35.28 (9)°in B. In each mol-ecule, the 1H-pyridin-2-one unit participates in inter-molecular N-H⋯O hydrogen bonding to another mol-ecule of the same type (A to A or B to B). The structure also displays π-π inter-actions between the pyridyl and the benzene rings of non-equivalent mol-ecules (viz., A to B and B to A).

2-[(E)-4-Meth-oxy-benzyl-idene]-1,2,3,4-tetra-hydro-naphthalen-1-one.

Project description:Two independent mol-ecules (A and B) comprise the asymmetric unit of the title compound, C(18)H(16)O(2). Mol-ecule B is virtually superimposable upon A. Minor differences are noted in the dihedral angles between the terminal benzene rings of 56.03 (10) and 54.62 (10)°, and in the orientations of meth-oxy groups with respect to the benzene rings to which they are attached [C-O-C-C torsion angles = 169.11 (19) and -172.37 (18)°]. The cyclo-hexene ring of each fused ring system has a screw-boat conformation. In the crystal, C-H⋯π inter-actions assemble mol-ecules into a supra-molecular array in the ab plane.

Crystal structure of (E)-2-(4-chloro-benzyl-idene)-3,4-di-hydro-naphthalen-1(2H)-one: a second monoclinic polymorph.

Project description:The title compound, C17H13ClO, is the second monoclinic polymorph to crystallize in the space group P21/c. The first polymorph crystallized with two independent mol-ecules in the asymmetric unit [Bolognesi et al. (1975 ▸). Acta Cryst. A31, S119; Z' = 2; no atomic coordinates available], whereas the title compound has Z' = 1. In the title polymorph, the dihedral angle between the plane of the benzene ring of the tetra-lone moiety and that of the 4-chloro-benzyl ring is 52.21 (11)°. The cyclo-hex-2-en-1-one ring of the tetra-lone moiety has a screw-boat conformation. In the crystal, mol-ecules are liked by pairs of C-H⋯π inter-actions forming inversion dimers. There are no other significant inter-molecular inter-actions present.

These dimers are further connected by C-H?? inter-actions, linking the mol-ecules into chains running along the a-axis direction.

7-Meth-oxy-3,4-dihydro-naphthalen-1(2H)-one.

Project description:In the title compound, C(11)H(12)O(2), the six-membered ketone ring fused to the 7-meth-oxy benzene ring adopts a slightly distorted envelope configuration with the central methyl-ene C atom being the flap. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions, which lead to supra-molecular layers in the bc plane.
