Organic-inorganic hybrid three-dimensional metal sulfite-oxalates with honeycomb-like structures.

The crystallographic signatures and characterization of two novel mixed metal hybrid open-frameworks [NaMn(CO)(SO)(HO)] 1 and [NaEu(CO)(SO)(HO)] 2 are reported for the first time; they are synthesized under hydrothermal conditions to generate 3D assemblies and honeycomb-like structures. They were further characterized by complementary techniques like PXRD, TGA and DSC. The magnetic properties of 1 show antiferromagnetic interactions between the metal centers and compound 2 shows good photoluminescence properties.
