In the fifth Si+3.33- site, Si+3.33- is bonded in a 10-coordinate geometry to four Sc3+, four Re+3.12+, and two Si+3.33- atoms. The Si–Si bond length is 2.78 Å. In the sixth Si+3.33- site, Si+3.33- is bonded in a 1-coordinate geometry to three Sc3+, four Re+3.12+, and two equivalent Si+3.33- atoms. In the seventh Si+3.33- site, Si+3.33- is bonded in a 11-coordinate geometry to two equivalent Sc3+, five Re+3.12+, and four Si+3.33- atoms. Both Si–Si bond lengths are 2.89 Å. In the eighth Si+3.33- site, Si+3.33- is bonded in a 1-coordinate geometry to three Sc3+, four Re+3.12+, and three Si+3.33- atoms. The Si–Si bond length is 2.50 Å.
