• New metal phosphites were prepared under solvent-free conditions.
• The cadmium phosphite contains an organic ligand.
• These compounds have 1D chain, 2D slab and 3D framework structures, respectively.
Three new metal phosphites, Cd(bpy)(H2PO3)2 (1), (H3O)2 · Co3(HPO3)4 (2), and H2dmen · Zn3(HPO3)4 (3), have been synthesized in a solvent-free flux of phosphorus acid, where bpy = 2,2′-bipyridine, and dmen = N,N-dimethylethylenediamine. Compound 1 represents the first example of cadmium phosphite incorporating an organic ligand. It has a 1D chain-like structure containing corner-sharing 4-rings. Compound 2 has a 2D slab-like structure containing Co3O12 trimers. Compound 3 has a 3D network with corner-sharing 4-ring chains linked by zinc ions. Upon photoexcitation at 286 nm, compound 1 exhibits extensive photoluminescence.
Three metal phosphites have been synthesized under solvent-free conditions. These compounds display different structures varying from 1D chain to 2D slab and 3D framework.Figure optionsDownload as PowerPoint slide
