2-(7-Hydroxy-2-naphthyloxy)-N-(6-methyl-2-pyridyl)acetamide
In the title compound, C(18)H(16)N(2)O(3), the dihedral angle between the naphthalene ring system and the pyridyl ring is 18.1 (8)°. The mol-ecules are inter-connected via C-H⋯O and O-H⋯O hydrogen bonds. Inversion-related mol-ecules are linked by O-H⋯O hydrogen bonds into cyclic centrosymmetric R(2) (2)(22) dimers. Intra-molecular N-H⋯O hydrogen bonding produces an S(5) ring motif. The crystal ...

In the crystal structure of the title mol-ecule, C(13)H(14)N(4), the two pyridyl rings are not coplanar but twisted about the C-N bond with an inter-planar angle of 71.1 (1)°. In the crystal, the mol-ecules form dimers, situated on crystallographic centres of inversion, which are connected via a pair of N-H⋯N hydrogen bonds. C-H⋯π-electron ring inter-actions are also present in the crystal stru...

A natural diastereomeric mixture of 5-(6-hydroxy-2,5,7,8-tetramethyl-chroman2-yl)-2-methyl-pentanoic acid methyl ester (1), was isolated from the soft coral Sinularia arborea. The structure of 1 was elucidated by spectroscopic methods and 1 displayed a significantly inhibitory effect on the generation of superoxide anion by human neutrophils.

In the title compound C(14)H(14)BrNO(3), the coumarin ring system is almost planar (r.m.s. deviation = 0.008 Å) and an intra-molecular C-H⋯O inter-action generates an S(6) ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, with the C=O unit of the coumarin ring system acting as the acceptor group, generating [010] C(8) chains. The chain connectivity is reinforced by two C-H⋯O ...
متن کامل2-Iodo-N-(6-methyl-2-pyridyl)benzamide
The asymmetric unit of the title compound, C(13)H(11)IN(2)O, comprises two crystallographically independent mol-ecules. The dihedral angles between the ring planes are 53.56 (9) and 72.14 (19)° in the two molecules. Pairs of inter-molecular N-H⋯N hydrogen bonds and I⋯O inter-actions link neighbouring mol-ecules into two different pairs of dimers, those involving N-H⋯N interactions having R(2) (...
