4-(1-Naphth­yl)benzoic acid

4-[(2-Hydr­oxy-1-naphth­yl)methyl­idene­amino]benzoic acid

The mol-ecule of the title compound, C(18)H(13)NO(3), is almost planar, the dihedral angle between the naphthalene and benzene ring systems being 4.04 (6)°. The mol-ecular conformation and packing are stabilized by intra-molecular O-H⋯N and inter-molecular O-H⋯O and C-H⋯O inter-actions.

3-(5,6,7,8-Tetra­hydro-2-naphth­yl)iso­benzofuran-1(3H)-one

The title compound, C(18)H(16)O(2), was prepared by reduction of 2-(5,6,7,8-tetra-hydro-2-naphtho-yl)benzoic acid with zinc dust. The benzene ring in the tetra-hydro-naphthyl substituent is nearly perpendicular to the plane of the isobenzofuran-1(3H)-one ring [87.15 (4)°]. The cyclo-hexane unit has a half-chair conformation in which two methylene groups in the tetra-methyl-ene bridge are disord...

A series of new heteroleptic Hg(II) complexes: Synthesis, crystal structures and photophysical properties

We report the synthesis of six new heteroleptic Hg(II) complexes (1–6) with general composition [Hg(II) (bpy)L2] where bpy = 2,20-bipyridine, L = benzoic acid (1), 2-amino benzoic acid (2), 3-amino benzoic acid (3), 4-amino benzoic acid (4), 2-hydroxy benzoic acid (5), 4-hydroxy benzoic acid (6). 1, 2, 4–6 are monomer with hexa coordinated Hg(II) center whereas 3 is a zig–zag 1D-polymer with he...

Application of Hammett Constant for Prediction of Acidity Properties of Substituted Benzoic Acid

Hammett constants (σ) can be important factor to understanding substitution and position effects on benzoic acid. This report describes a computational study of ∆G◦ and σ for six substituted benzoic acid (X= F,Cl ,OH ,NH2 ,CN,NO2 )and phenylacetic acid substituted (X=OH ,NH2 ) at para and meta positions ingas and aqueousphases by DFT method and comparesit to available experimental and theoretic...
