The successful synthesis of new pyrimidine based organic ligands with terminal carboxylate and oxime functional groups, followed by their employment in metallogrid self-assembly has yielded three tetranuclear [Ni4(L1)4]∙2CH3CN∙4CH3OH·4H2O (1), [Cu4(HL1′)4]∙8CH3OH·28H2O (2) and [Ni4(H2L2)4](CF3SO3)8∙4CH3NO2·8H2O (3), [2 × 2] metallogrid complexes. The complexes have been well characterized by elemental analyses, IR spectra, UV-vis spectra and X-ray structural analyses. Variable temperature magnetic measurements/studies done on these three complexes followed by magnetic data fitting suggest that all the three complexes are dominated by intramolecular antiferromagnetic exchange coupling.
