Abstract:
Metal-organic layers (MOLs), a category of two-dimensional materials, have attracted wide interest due to their molecular tunability and the ease of surface modification. Herein, we reported the synthesis and structural determination of a free-standing MOL, {[Hf6O8H4(HCOO)2(H2O·OH)4]3[Hf12O16H8(HCOO)6.8(H2O·OH)11.2](TPO)8}, constructed from Hf6-oxo and Hf12-oxo clusters as secondary building units (SBUs) and the tris(4-carboxylphenyl)phosphine oxide (TPO) ligand. We establish a structure model of this new MOL based on the combined information from different characterization methods.
