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...

the synthesis and properties of new monoazo dyes derived from the diazonium salts of paminobenzoic acid, 3-trifluoromethyl aniline , 4-trifluoromethyl aniline are considered .theprepared compounds were characterized by uv-visible , ft-ir and h nmr spectroscopictechniques . the effect of varying solvent upon the absorption ability of p-amino benzoic acidcoupled with 4,4 —diethyl aniline , anilin...

In the title compound, C(10)H(11)NO(4)·H(2)O, the carboxyl group is twisted at a dihedral angle of 6.1 (3)° with respect to the benzene ring. In the crystal, the organic mol-ecules are linked by pairs of O-H⋯O hydrogen bonds involving both carboxyl groups, forming zigzag chains propagating along the b-axis direction. The water mol-ecules form [100] chains linked by O-H⋯O hydrogen bonds. The org...

A 4-aza-1-azoniabicyclo-[2.2.2]octane cation, a 2-amino-benzoate anion and a neutral 2-amino-benzoic acid mol-ecule comprise the asymmetric unit of the title compound, C(6)H(13)N(2) (+)·C(7)H(6)NO(2) (-)·C(7)H(7)NO(2). An intra-molecular N-H⋯O hydrogen bond occurs in the anion and in the neutral 2-amino-benzoic acid mol-ecule. The cation provides a charge-assisted N-H⋯O hydrogen bond to the ani...
