标题化合物，重钛酸氢钙(IV)，是第二个以辉石硅酸盐Na2Ti2Si2O9(红柱石)的同型结构结晶的例子。∞-1[Sn2O8]链和辉石型∞-1[Al2O6]链是通过共享O原子沿b轴形成的。钙原子位于所得到的通道中，并显示出配位数为7。
The title compound, dicalcium nonaoxidodistannate(IV)dialuminate, is the second example which crystallizes in the isotypic structure of a pyroxene silicate, Na2Ti2Si2O9 (ramsayite). ∞ 1[Sn2O8] chains and pyroxene-type ∞ 1[Al2O6] chains are formed along the b axis by sharing O atoms. The Ca atoms are situated in the resulting channels and exhibit a coordination number of 7.
