Crystals of a new nesosilicate, tricalcium diyttrium trisilicon oxide, were prepared from a silicate melt by slow cooling. The structure was refined in space group Pnma and has nine-, eight- and seven-coordinate sites for Ca2+ and Y3+ cations. The structural formula can be expressed as (Ca0.84Y0.16)(Ca0.41Y0.59) 2(Ca0.67Y0.33)2 (SiO4)3.
