Abstract
The versatile coordination abilities of o-phthalic acid, containing two carboxylic groups in ortho-position, allow for a variety of structures ranging from discrete complexes to 1D, 2D and 3D architectures. This review focuses on the synthesis and structural particularities of zinc(II) phthalates with ancillary N-containing ligands such as pyridine, imidazole and their derivatives [3-, 4-methylpyridine, and 1-, 2-methylimidazole], and 2,2′-, 4,4′-bipyridine. The coordination features manifested by this ligand are analyzed and discussed.
Keywords: o-Phthalic acid, zinc(II) complexes, carboxylates, coordination polymers, N-donor ligands
