Solution

The correct option is C $S i_{2} O_{7}^{6 -}$

Pyrosilicates are silicates which contain $S i_{2} O_{7}^{6 -}$ . They are formed by joining two tetrahedral $S i_{2} O_{4}^{4 -}$ . When two $S i_{2} O_{4}^{4 -}$ are joined, there is removal of one oxygen atom and the two units join at the corner oxygen atom. Example is thortveitite, $S c_{2} S i_{2} O_{7}$ . The structure of pyrosilicate is:
