摘要
The title compound, dicalcium nonaoxidodistannate(IV)-dialuminate, is the second example which crystallizes in the isotypic structure of a pyroxene silicate, Na2Ti2Si2O9 (ramsayite). (1)(infinity)[Sn2O8] chains and pyroxene-type (1)(infinity)[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.
