4-(4-Methoxy-phen-yl)-4-methyl-2,6-diphenyl-4H-thio-pyran.

ABSTRACT: The asymmetric unit of the title compound, C(25)H(22)OS, comprises two similar 4-(4-methoxy-phen-yl)-4-methyl-2,6-diphenyl-4H-thio-pyran mol-ecules. In each, the six-membered thio-pyran ring adopts a planar conformation (r.m.s. deviation of 0.041Å for the ring in one mol-ecule and 0.008?Å in the other). The methoxy-phenyl substituent is in a pseudo-axial position. The crystal studied is an inversion twin, with a domain ratio of 0.39?(6).

Project description:The two aromatic rings in the title compound, C(15)H(12)Cl(2)N(2)O(2)S, enclose a dihedral angle of 37.49?(6)°. The mol-ecule exists in the solid state in its thione form with typical thio-urea C-S and C-O bonds lengths, as well as shortened C-N bonds. An intra-molecular N-H?O hydrogen bond stabilizes the mol-ecular conformation. In the crystal, mol-ecules are connected by N-H?O and N-H?S hydrogen bonds, forming chains running along the a axis.

2,6-Bis(3-methoxy-phen-yl)-3-methyl-piperidin-4-one.

Project description:In the mol-ecule of the title compound, C(20)H(23)NO(3), the bulky methoxy-phenyl substituents at the equatorial 2,6-positions crowd the vicinity of the equatorial amino H atom and prevent it from forming inter-molecular hydrogen bonds. The piperidine ring adopts a distorted chair conformation.

Project description:In the title compound, C(10)H(11)N(3)O(2), the triazole ring has a dihedral angle of 11.55?(2)° relative to the benzene ring.

N'-[(1E)-(2,6-Difluoro-phen-yl)methyl-idene]thio-phene-2-carbohydrazide.

Project description:In the title compound, C(12)H(8)F(2)N(2)OS, the thienyl ring is disordered over two positions, with the S atom of the major component [occupancy = 75.03?(18)%] oriented away from an ortho-F atom of the benzene ring. The mol-ecule is nearly planar, the dihedral angle between the thio-phene and benzene rings being 6.19?(18) (in the major component) or 3.5?(6)° (in the minor component). The azomethine C=N double-bond in the mol-ecule is of an E configuration. In the crystal, mol-ecules are linked by pairs of N-H?O hydrogen bonds, generating inversion dimers.

4-Methyl-2,4,6-triphenyl-4H-thio-pyran.

Project description:The six-membered thio-pyran ring in the title compound, C(24)H(20)S, adopts a flattened boat conformation, with the S atom displaced by 0.273?(2)?Å and the 3-methyl-ene C atom by 0.294?(3)?Å from the plane of the other four sp(2)-hydridized C atoms. The methyl group on the methyl-ene carbon lies in a axial position with the phenyl equatorial.

4-Hy-droxy-6-methyl-3-[3-(thio-phen-2-yl)acrylo-yl]-2H-pyran-2-one.

Project description:The title compound, C13H10O4S, crystallizes with two mol-ecules in the asymmetric unit in which the rings make dihedral angles of 3.9?(1) and 6.0?(1)°; this planarity is due in part to the presence of an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring in each mol-ecule. Both mol-ecules represent E isomers with respect to the central C=C bond. In the crystal, mol-ecules are linked by C-H?O inter-actions into a three-dimensional network.

Project description:In the title compound, C(23)H(22)N(2)O(3), the pyran ring adopts a twisted boat conformation.
