方钠石笼中只含有一个电子作为非骨架“阴离子”，非常适合研究溶剂化的“电子”维格纳晶格以及笼内和笼间电子势能表面的定量映射。本文报道了Na3[](ABO4)3·nH2O(A；B=Al，Ga；Si，Ge)形式的无阴离子笼状结构的直接合成，作为合成方钠石电子的可能的前驱体。提出了一种由Na4[OH](AlSiO4)3.1.72H2O制备Na3[](AlSiO4)3.4H2O的低温方钠石脱羟基化法.
The sodalite cage containing only an electron as a nonframework «anion» is well adapted for the study of solvated «electride» Wigner lattices and quantitative mapping of the intra- and intercage electronic potential surfaces. In this paper we report the direct synthesis of anion free cage structures of the form Na 3 [] (ABO 4 ) 3 .nH 2 O (A; B=Al, Ga; Si, Ge) as possible precursors for sodalite electride synthesis. A novel, low-temperature sodalite dehydroxylation method is presented for the preparation of Na 3 [] (AlSiO 4 ) 3 .4H 2 O from Na 4 [OH](AlSiO 4 ) 3 .1.72H 2 O
