In the fifth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six Mg2+ and three Si+1.33- atoms. There are a spread of Si–Si bond distances ranging from 2.41–2.51 Å. In the sixth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six Mg2+ and three Si+1.33- atoms. There are a spread of Si–Si bond distances ranging from 2.41–2.50 Å. In the seventh Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to five Mg2+ and four Si+1.33- atoms. There are two shorter (2.49 Å) and one longer (2.50 Å) Si–Si bond lengths. In the eighth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to five Mg2+ and four Si+1.33- atoms. There are one shorter (2.49 Å) and one longer (2.51 Å) Si–Si bond lengths. In the ninth Si+1.33- site, Si+1.33- is bonded in a 1-coordinate geometry to five Mg2+ and three Si+1.33- atoms. In the tenth Si+1.33- site, Si+1.33- is bonded in a 1-coordinate geometry to five Mg2+ and three Si+1.33- atoms. In the eleventh Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six Mg2+ and three Si+1.33- atoms. In the twelfth Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six Mg2+ and three Si+1.33- atoms.« less
