Abstract

Three new tetranuclear square Cu(II) and Ni(II), [2 × 2] grid complexes comprising Symmetrical ditopic open chain ligands with terminal carboxylate/oxime functions and central pyrimidine ring are reported. These [2 × 2] square grids are dominated by intramolecular antiferromagnetic exchange coupling.
