摘要：
Two new purely inorganic cationic telluritenetworks, [Cu2F(Te2O5)](BF4)and [Ag18O2(Te4O9)(4)(Te3O8)(BF4)(2)]center dot 2HBF(4), have been hydrothermally synthesized under mild conditions,and both compounds exhibit similar lamellar cationic layers with intercalatedtetrafluoroborates ions. Magnetic analysis shows that [Cu2F(Te2O5)](BF4) exhibits a mainlyshort-range antiferromagnetic ordering within the 2D layer with aspin-singlet ground state. Further characterization of the physicalproperties includes powder XRD, IR and Raman spectroscopy, SEM-EDS,UV-vis-NIR diffuse reflectance, and TG analyses. Two new purely inorganic cationic tellurite networksof Group IBmetal-based tetrafluoroborates, namely, [Cu2F(Te2O5)](BF4), 1, and [Ag18O2(Te4O9)(4)(Te3O8)(BF4)(2)]center dot 2HBF(4), 2, have been hydrothermally synthesized under mildconditions. The prepared materials have been characterized by single-crystalX-ray diffraction, powder X-ray diffraction, IR and Raman spectroscopy,SEM-energy-dispersive spectroscopy, UV-vis-NIRdiffuse reflectance, magnetic study, and TG analyses. Single-crystaldiffraction studies show that both materials have similar cationicCu/Ag tellurite layers with tetrafluoroborates as interlamellar charge-balancinganions. Magnetic results indicate that [Cu2F(Te2O5)](BF4), 1, exhibits a mainlyshort-range antiferromagnetic ordering within the 2D layer, and furtherdetailed analysis of magnetic susceptibility analysis confirms a spin-singletground state with an energy gap of 85 K.
