characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction. The thermal stabilities and luminescence properties of compounds C1–C5 were investigated. The N-donor ligands influence the coordination mods of the Cd(II) centers and dimensionality of the structures and H3PBO accept either bridging and chelating modes. C2 exhibits a 3-connected 2D network of a hcb topology with a
