In the title compound, C(14)H(10)FNO(2), the benzene rings make a dihedral angle of 57.50 (13)°, and the molecule has an E configuration about the C=N bond. In the crystal, molecules are linked via pairs of O-H⋯O hydrogen bonds, forming inversion dimers.

In the title compound, C(14)H(13)NO(4)S, the dihedral angle between the aromatic rings is 35.47 (10)°. In the crystal, adjacent mol-ecules are connected by pairs of O-H⋯O hydrogen bonds, forming head-to-head centrosymmetric dimers typical for carb-oxy-lic acids. Adjacent dimers are further linked through C-H⋯O inter-actions on one side and N-H⋯O inter-actions on the other, generating [010] chains.

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...

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...
