Two　novel　Zn2+　organic　phosphonate　Zn(4,　4′-bipy)(HBCP)　1　and　[Zn2(phen)2(BCP)(H2BCP)]　·H2O2　were　hydrothermally　synthesized.　The　compound　1　is　with　two-dimensional　layer　framework　whereas　the　compound　2　is　zero-　dimensional　structure.　The　Zn2+　ion　is　four-coordinated　in　compound　1　while　five　or　six-coordinated　in　compound　2.　The　relationship　between　their　properties　and　structures　was　studied　by　using　FTIR,　two-dimensional　(2D)　correlation　infrared　spectroscopy　under　thermal　perturbation,　fluorescence　and　UV-Vis　DRS　spectrum　etc.　Upon　light　excitation　at　350　nm,　the　compound　1　exhibits　luminescence　with　a　strong　wide　emission　at　412　nm　and　a　weak　emission　at　520　nm,　while　the　compound　2　exhibits　luminescence　with　a　wide　emission　only　at　398　nm　under　light　excitation　at　336　nm.
