从各种含镓、锗钠长石的结构参数出发，研究了它们之间的关联。这使得将镓和锗引入骨架位置的影响得以研究。与掺入镓和锗相关的骨架膨胀主要由围绕轴线的协同旋转和骨架T-O-T键角的增加来调节。研究了骨架T-O-T键角、T-O键长和四面体倾角等结构参数之间的关系，发现它们与铝硅酸盐的结构参数具有相似的关系。
Correlations derived from the structural parameters of a wide range of gallium and germanium containing sodalites have been examined. This has allowed the effect of introducing gallium and germanium onto the framework sites to be studied. The framework expansion associated with gallium and germanium incorporation is principally accommodated by co-operative rotations about the axis and an increase in framework T–O–T bond angle. Correlations involving structural parameters such as framework T–O–T bond angle, T–O bond lengths and tetrahedral tilt angle have been examined and have been shown to be analogous to those found for their aluminosilicate counterparts.
