4-Methyl-2,4,6-triphenyl-4H-thiopyran
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.
متن کامل4-(4-Methoxyphenyl)-4-methyl-2,6-diphenyl-4H-thiopyran
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 inve...
متن کامل3-Methyl-4H-chromen-4-one
In the title chromenone derivative, C(10)H(8)O(2), the two fused six-membered rings are coplanar, with a mean deviation of 0.0261 (1) Å from the plane through the non-H atoms of the rings. The carbonyl and methyl substituents of the pyran ring also lie close to that plane, with the O and C atoms deviating by 0.0557 (1) and 0.1405 (1) Å, respectively. In the crystal, weak C-H⋯O contacts form cha...
متن کامل3,4,5-Trimethyl-2,4,6-triphenyl-4H-thiopyran
The six-membered thio-pyran ring in the title compound, C(26)H(24)S, adopts a boat conformation, with the S atom displaced by 0.478 (2) Å and the 3-methyl-ene C atom by 0.644 (2) Å from the plane of the other four sp(2)-hydridized C atoms. The methyl group on the methyl-ene carbon lies in a pseudo-equatorial position and the phenyl ring in a pseudo-axial position.
متن کاملTriphenyl{(E)-4-[4-(phenyldiazenyl)phenyl]-4H-1,2,4-triazol-1-yl}boron
In the title compound, C(32)H(26)BN(5) or [(C(14)H(11)N(5))B(C(6)H(5))(3)], the B atom is approximately tetra-hedrally coordinated. The diazo unit is in a trans conformation, which is generally more stable than a cis one for aromatic azo compounds. The crystal structure features very weak C-H⋯π inter-actions. The dihedral angles between the central benzene ring and the terminal rings in the het...
