The title compound, C26H24Cl2N2, crystallizes with two independent mol-ecules (1 and 2) in the asymmetric unit. In mol-ecule 1, the two phenyl and 2,6-di-chloro-phenyl rings are inclined to the imidazole ring at angles of 74.12 (14), 26.13 (14) and 67.30 (14)°, respectively. In mol-ecule 2, due to the different mol-ecular environment in the crystal, the corresponding angles are different, viz. ...

The title compound, C(17)H(16)O(3)S, was prepared by the oxidation of 2,5,7-trimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring exhibits a dihedral angle of 81.16 (4)° with the plane of the benzofuran fragment. The crystal structure is stabilized by π-π inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distanc...

The asymmetric unit of the title compound, C15H15NO2, contains two independent mol-ecules (A and B). The di-methyl-phenyl ring, the phenyl ring and the central carbamate N-C(=O)-O group are not coplanar. In mol-ecule A, the di-methyl-phenyl and phenyl rings are inclined to the carbamate group mean plane by 27.71 (13) and 71.70 (4)°, respectively, and to one another by 84.53 (13)°. The correspon...

In the mol-ecule of the title compound, C(16)H(14)O(3), the aromatic rings are oriented at a dihedral angle of 72.02 (6)°. The heterocyclic ring adopts a twisted conformation. In the crystal structure, there are C-H⋯π contacts between the heterocyclic and phenyl rings, and between the methyl group and methoxy-phenyl ring.

In the title syndone (1,2,3-oxadiazol-3-ylium-5-olate) compound, C(21)H(16)ClN(5)O(4)S, the dihedral angle between the benzene and oxadiazole rings is 55.62 (11)° and that between the triazine and the chloro-substituted phenyl rings is 82.45 (9)°. There is an intra-molecular C-H⋯S hydrogen bond, which generates an S(5) ring motif. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrog...

In the title compound, C(27)H(19)NO(2)S, the naphtho-carbazole unit is approximately planar (r.m.s. deviation = 0.002 Å) except for the N atom, which is displaced by 0.122 (1) Å out of the mean plane. The dihedral angle between the naphtho-carbazole mean plane and the phenyl ring of the phenyl-sulfonyl substituent is 83.16 (3)°. An inter-molecular C-H⋯π inter-action involving the phenyl group a...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(22)H(14)FN(3), which differ slightly in the relative orientations of the naphthyl and phenyl groups with respect to the pyridyl ring framework. In one mol-ecule, the naphthyl ring system and the phenyl ring form dihedral of angles 56.50 (2) and 48.23 (3)°, respectively, with the pyridyl ring plane. In the other...

The title compound, C20H16ClNO3S, is built up from three fused rings, one five- and two six-membered rings, linked to a 3-eth-oxy-carbonyl group and to a 4-chloro-phenyl ring. The hydropyran ring has a flattened envelope conformation, with the C atom substituted by the 4-chloro-phenyl ring as the flap (displaced by 0.077 (2) Å from the plane through the other atoms). The fused three-ring system...

The title compound, C26H23F3N4O, crystallizes with two symmetry-independent mol-ecules in the asymmetric unit, denoted A and B, which differ mainly in the rotation of the meth-oxy-phenyl ring. The -CF3 group of mol-ecule B is disordered by rotation, with the F atoms split over two sets of sites; the occupancy factor for the major component is 0.853 (4). The dihedral angles between the pyrimidin...

The title compound, C(22)H(18)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(4-methoxy-phen-yl)propane-1,3-dione. The central pyrazole ring forms dihedral angles of 16.83 (5), 48.97 (4) and 51.68 (4)°, respectively, with the methoxy-phenyl, phenyl and hydroxy-phenyl rings. The crystal packing is stabilized by O-H⋯N hydrogen bonding.
