1,2,3-Triphenyl-1,2-dihydroquinoxaline
The title compound, C(26)H(20)N(2), first reported in 1891, was obtained as a by-product in the preparation of benzildianil from benzil and excess aniline. The dihedral angles between the fused benzene ring and the pendant phenyl rings are 17.93 (11), 53.18 (10) and 89.08 (12)°.
متن کاملLophine (2,4,5-triphenyl-1H-imidazole)
The title compound, C(21)H(16)N(2), has been known since 1877. Although the crystal structure of 36 derivatives of lophine are known, the structure of parent compound has remained unknown until now. The three phenyl rings bonded to the imidazole core are not coplanar with the latter, with dihedral angles of 21.4 (3), 24.7 (3), and 39.0 (3)°, respectively, between the phenyl ring planes in the 2...
متن کامل4-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 کاملTriphenyl(3,4,5-trimethoxybenzyl)phosphonium chloride monohydrate
The asymmetric unit of the title salt, C(28)H(28)O(3)P(+)·Cl(-)·H(2)O, contains a benzyl-triphenyl-phospho-nium cation, a chloride counter-ion, and a water mol-ecule of crystallization. The 3,4,5-trimeth-oxy substituents of the benzylic functionality are arranged with the 3,5-methyl groups lying approximately in the aromatic ring plane while the 4-methyl group is out of the plane.
متن کاملTriphenyl[(triphenylphosphoranylidene)amino]phosphonium tetrakis(pentafluorophenyl)borate
In the title molecular salt, C36H30NP2(+)·C24BF20(-), the P-N bond lengths in the cation are equal [1.573 (2) and 1.572 (2) Å], indicating a resonance structure and the P-N-P bond angle is 144.79 (12)°. In the crystal, weak C-H⋯F interactions link the cations and the anions.
