(E)-N-[2-(Biphenyl-4-ylvinyl)phenyl]furan-2-carboxamide
In the title mol-ecule, C(25)H(19)NO(2), the furyl ring is twisted by 46.3 (1)° with respect to the phenyl-ene ring bearing the amido group. In the stilbene unit, the two phenyl-ene rings (i.e. the rings connected through the -CH=CH- fragment) are twisted by 59.2 (1)°; in the biphenyl-ene unit, the two benzene rings are twisted by 35.5 (1)°. In the crystal structure, mol-ecules are linked by an...
متن کاملCrystal structure of N-hydroxyquinoline-2-carboxamide monohydrate
The title compound, C10H8N2O2·H2O, consists of an N-hy-droxy-quinoline-2-carboxamide mol-ecule in the keto tautomeric form and a water mol-ecule connected through an O-H⋯O hydrogen bond. The N-hy-droxy-quinoline-2-carboxamide mol-ecule has a nearly planar structure [maximum deviation = 0.062 (1) Å] and only the hy-droxy H atom deviates significantly from the mol-ecule plane. In the crystal, π-π...
متن کاملCrystal structure of dibenzoyl diselenide.
C14H10O2Se2 is monoclinic, P2(1)/c. The unit-cell dimensions at 293 K are a = 12.795(2), b = 12.126(2), c = 9.0179(13)A, beta = 107.074(6)degrees, V = 1337.5(3)A3, and Z = 4. The R value is 0.048 for 2319 observed reflections. The dihedral angle between the plane C4-C7(O2)-Se1 and C9-C8(O1)-Se2 is 85.6(2)degrees, keeping the Se atom unshared electron pairs in a more stable configuration with th...
متن کاملCrystal structure of 4,4-dibutyl-2-phenyl-3,4-dihydroquinazoline
In the title compound, C22H28N2, the dihedral angle between the planes of the phenyl ring and the di-hydro-quinazoline ring system (r.m.s. deviation = 0.030 Å) is 24.95 (7)° and both n-butane chains assume all-trans conformations. In the crystal, N-H⋯N hydrogen bonds link the mol-ecules into C(4) chains propagating in the [001] direction.
متن کاملCrystal structure of 2-(diphenylphosphanyl)phenyl 4-(hydroxymethyl)benzoate
The title compound, C26H21O3P, was obtained as by-product due to the hydrolysis of the desired tosyl-ated compound. The dihedral angles between the three aromatic rings attached to the P atom lie in the range 78.1 (1)-87.6 (1)°. The hy-droxy-methyl group is disordered between two conformations in a 0.719 (9):0.281 (9) ratio. The hy-droxy H atom is not involved in inter-molecular inter-actions, ...
