In the title compound, C(17)H(17)N(2)O(+)·BF(4) (-), the central imidazolium ring makes dihedral angles of 74.58 (9) and 40.10 (6)° with the phenyl and 2-methoxy-phenyl rings, respectively. In the crystal, a strong π-π inter-action is observed between the imidazolium and 2-methoxy-phenyl rings, with a centroid-centroid distance of 3.5115 (15) Å. In addition, C-H⋯F and C-H⋯O hydrogen bonds and C...

In the title compound, [ZnCl(2)(C(11)H(9)N)(2)], the Zn(2+) cation lies on a twofold axis and is coordinated by two Cl(-) anions and the N atoms of two 2-phenyl-pyridine ligands, forming a ZnN(2)Cl(2) polyhedron with a slightly distorted tetra-hedral coordination geometry. The dihedral angle between the phenyl ring and the metal-bound pyridine ring is 50.3 (4)° for each 2-phenyl-pyridine ligand...

In the title compound, C(26)H(27)BrN(3)O(3)P, the central pyrazole ring forms a dihedral angle of 71.7 (2)° with the bromo-phenyl ring. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with R(2) (2)(10) ring motifs. Four C atoms of the 3-phenyl ring are disordered over two sets of sites [site occupancies = 0.745 (6) and 0.225 (6)].

In the title compound, C(19)H(15)NO(5), the dihedral angle between the naphthalene ring system and the benzene ring is 61.97 (5)°. The dihedral between the naphthalene ring system and the bridging carbonyl C-C(=O)-C plane is 54.68 (6)°, far larger than that [12.54 (7)°] between the phenyl group and the bridging carbonyl group. The nitro group and the phenyl ring are almost coplanar [O-N-C-C tor...

In the mol-ecule of the title compound, C(18)H(14)O(3), there is an intra-molecular O-H⋯O=C hydrogen bond between the carbonyl and hy-droxy groups on the naphthalene ring system. The angles between the C=O bond vector and the least-squares planes of the naphthalene ring system and the phenyl ring are 30.58 (6) and 42.82 (7)°, respectively, while the dihedral angle between the naphthalene ring s...

In the title compound, C(22)H(24)N(4)S, the methylphenyl and isobutylphenyl rings are inclined at an angle of 79.98 (1)° and they form dihedral angles of 4.59 (1) and 75.47 (1)°, respectively, with the triazolothia-diazole unit. An intra-molecular C-H⋯S hydrogen bond generates an S(5) ring motif. The crystal structure is stabilized by inter-molecular C-H⋯N hydrogen bonds and weak C-H⋯π and π-π ...

The title compound, C(29)H(17)FN(4)O(2), may be used as a new precursor for obtaining bioactive mol-ecules. There are two crystallographically independent mol-ecules in the asymmetric unit. The phenyl ring, 4-fluoro-phenyl ring and 2-naphth-yloxy ring are twisted with respect to the pyrrolopyrimidine ring by 52.30 (11)/49.05 (11), 80.94 (10)/88.36 (10) and 60.58 (7)/83.76 (7)°, respectively. Th...

The overall shape of the mol-ecule of the title compound, C(17)H(15)BrO(2), can be described by the dihedral angles between three planar fragments: 1-bromo-2-meth-oxy-phenyl ring [maximum deviation = 0.003 (2) Å], the central prop-2-en-1-one chain [maximum deviation = 0.005 (2) Å], and the methyl-phenyl ring [maximum deviation = 0.004 (2) Å]. The terminal planes are twisted by 10.37 (12)°, whil...
