Two new magnesium phosphite-oxalates were prepared under solvent-free conditions using different amines as structure-directing agents. They feature noncentrosymmetric structures with sql and dia topologies, respectively. The two compounds show moderate second-harmonic generation (SHG) responses under 1064 nm laser irradiation. Theoretical calculations were performed to reveal the origin of their SHG responses.
