A new metal-oxo-clusters-based inorganic framework[NaCo2Mo2O7(OH)3]n (NaCoMo),named as 3D platelike ternary-oxo-cluster,has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction structure analysis,FT-IR spectroscopy,powder X-ray diffraction (PXRD),scanning electron microscope (SEM),energy-dispersive X-ray spectroscopy (EDS) analyses,X-ray photoelectron spectroscopy(XPS) and thermogravimetric analysis (TGA).Structure analysis reveals that there are no classical build-ing units in NaCoMo,and the asymmetric units of NaCoMo are directly extended into a new platelike 3D structure.Density functional theory calculations (DFT) indicates that the crystal formation process is exothermic and the structure is extremely stable.In addition,the compound presents excellent catalytic activity in the condensation and cyclization reaction of sulfonyl hydrazides and 1,3-diketones to synthe-size pyrazoles,and the yield of the desired product is up to 99％.The successful synthesis of NaCoMo represents the discovery of a new kind of non-classical polyoxometalates.
