1-[6-(6-Acetylpyridin-2-yl)pyridin-2-yl]ethanone
In the title compound, C(14)H(12)N(2)O(2), the asymmetric unit comprises one half-mol-ecule with an inversion center between the pyridine rings. The rings are trans coplanar with the acetyl groups deviating slightly from the mean planes, making a dihedral angle of 4.63 (4)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, forming a supra-molecular sheet paral...
متن کامل1-{6-Chloro-2-[(2-chloro-6-methylquinolin-3-yl)methoxy]-4-phenylquinolin-3-yl}ethanone
In the title compound, C(28)H(20)Cl(2)N(2)O(2), the 2-chloro-quinoline and 6-chloro-quinoline ring systems are twisted slightly, making a dihedral angle of 4.05 (3)°. The dihedral angle between the 2-quinoline ring system and the phenyl ring attached to it is 74.43 (5)°. In the crystal structure, a pair of inter-molecular C-H⋯O hydrogen bonds connect the mol-ecules, forming centrosymmetric dime...

In the title compound, C17H15BrO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.016 (2) Å] and the 2-bromo-phenyl ring is 82.93 (6)°. In the crystal, mol-ecules are linked via pairs of C-H⋯π hydrogen bonds and π-π inter-actions between the benzene and furan rings of neighbouring mol-ecules [centroid-centroid distance = 3.881 (2) Å] into inversion-r...
متن کاملCrystal structure of 2-(2,3-dimethoxynaphthalen-1-yl)-3-hydroxy-6-methoxy-4H-chromen-4-one
In the title compound, C22H18O6, the dimeth-oxy-substituted naphthalene ring system is twisted relative to the 4H-chromenon skeleton by 88.96 (3)°. The two meth-oxy substituents are tilted from the naphthalene ring system by 1.4 (4) and 113.0 (2)°, respectively. An intra-molecular O-H⋯O hydrogen bond closes an S(5) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds form inversion dimers ...
