摘要：

The synthesis, structure and properties of Na2Zn(OEt)(4)(HOEt)(5), having the right Na:Zn ratio for sol-gel synthesis of the highly Na-ion conducting ceramic Na1.8Zn0.9Si1.1O4, is described. It was synthesised in high yield by a metathesis reaction of ZnCl2 and 4NaOEt in ethanol or ethanol/toluene solvent. The structure was determined by single-crystal X-ray methods and consists of two symmetry related polymeric strands with the metal sequence...-Zn-Na-Na-Zn-.... Extensive hydrogen bonding is present within each chain. Further characterization was made with IR- and Raman-spectroscopy and thermo-calorimetry, showing that the compound is stable to 65 degrees C.
