The copper(II) and Mn(II) complexes with nicotinic acid and imidazole ligands have potentially donor and acceptor character in the formation of a coordination bond and a hydrogen bond. They can function as a ligand-complex or as a self-complementary building block for the construction of the assembly structure due to the formation of a coordination bond or a hydrogen bond. In such self-complementary complexes, the monomer is stabilized as a protonated species under acidic conditions, while under appropriate basic conditions the generated imidazolate nitrogen atom coordinates to the Cu(II) and Mn(II) ion of the adjacent unit or hydrogen-bonds to the imidazole as well as nicotinic acid group of the adjacent unit to give assembly structures in the crystals, depending on the ligand framework and the preferred coordination number of the Cu(II) and Mn (II) ion. Numerous methods for the synthesis of imidazole and nicotinic acid complexes of Cu(II) and Mn(II) also their various structure reactions offer enormous scope in the field of medicine chemistry.
