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

ABSTRACT: 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.

3-Benzyl-8-meth-oxy-2-sulfanyl-idene-1,2,3,4-tetra-hydro-quinazolin-4-one.

Project description:The tetra-hydro-quinazole fused-ring system of the title compound, C(16)H(14)N(2)O(2)S, is roughly planar (r.m.s. deviation = 0.039?Å); the phenyl ring of the benzyl substituent is aligned at 78.1?(1)° with respect to the mean plane of the fused-ring system. In the crystal, two mol-ecules are linked by a pair of N-H?S hydrogen bonds about a center of inversion, generating a dimer.

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).

(2E)-2-(Thio-phen-2-yl-methyl-idene)-1,2,3,4-tetra-hydro-naphthalen-1-one.

Project description:In the title compound, C(15)H(12)OS, the cyclo-hexene ring has a twisted boat conformation with the C atom between the ketone and methyl-ene atom and this methyl-ene C atom lying 0.280?(3) and 0.760?(3)?Å, respectively, from the plane through the remaining four atoms (r.m.s. deviation = 0.004?Å). The dihedral angle between the benzene and thio-phene rings [21.64?(9)°] indicates an overall twist in the mol-ecule. The thio-phene S and ketone O atoms are anti, an orientation that allows the close approach of these atoms [3.3116?(17)?Å] in the crystal structure and which leads to the formation of helical supra-molecular chains along the c axis.

2-(1,2,3,4-Tetra-hydro-naphthalen-1-yl-idene)hydrazinecarbothio-amide.

Project description:The mol-ecular structure of the title compound, C(11)H(13)N(3)S, is not planar: the maximum deviation from the mean plane of the non-H atoms is 0.521?(2)?Å for an aliphatic C atom, which corresponds to an envelope conformation for the non-aromatic ring. The hydrazinecarbothio-amide substituent and the benzene ring have maximum deviations from the mean planes through the non-H atoms of 0.0288?(16) and 0.0124?(27)?Å, respectively, and the dihedral angle between the two planes is 8.84?(13)°. In the crystal, mol-ecules are linked into chains along [1[Formula: see text]0] by pairs of N-H?S hydrogen bonds between mol-ecules related by centres of symmetry.

Crystal structure of 3-benzyl-1-[(1,2,3,4-tetra-hydro-naphthalen-1-yl-idene)amino]-thio-urea.

Project description:In the title compound, C18H19N3S, the dihedral angle between the planes of the benzene rings is 58.63 (8)°. The six-membered ring bonded to the thio-semicarbazide group (r.m.s. deviation = 0.038 Å) adopts a sofa conformation, with one of the methyl-ene-group C atoms as the flap. A short intra-molecular N-H⋯N contact is observed. In the crystal, mol-ecules are linked by weak N-H⋯S inter-actions to generate C(4) chains propagating in the [010] direction, with adjacent mol-ecules related by glide symmetry.

1-[(Cyclo-propyl-meth-oxy)meth-yl]-5-ethyl-6-(4-methyl-benzyl)-1,2,3,4-tetra-hydro-pyrimidine-2,4-dione.

Project description:The pyrimidine ring in the title compound, C(19)H(24)N(2)O(3), is nearly planar (r.m.s. deviation = 0.008?Å); the C atom at the 5-position deviates by 0.054?(3)?Å from the mean plane and the C atom at the 6-position by 0.006?(3)?Å in the opposite direction. The benzene ring is approximately perpendicular to the pyrimidine ring [dihedral angle = 83.90?(10)°]. The amino group is hydrogen-bond donor to the exocyclic O atom at the 2-position of an adjacent mol-ecule, the hydrogen bond generating an inversion dimer. The cyclo-propyl ring is disordered over two sets of sites with the major component having 71.5?(4)% occupancy.
