A view of the aqua–[SiF6]2− chains dominating the connectivity in the structure of (II). The [SiF6]2− anion (acceptor of six hydrogen bonds) and the water molecules (acceptors of one and donors of two hydrogen bonds) provide six- and three-connected net nodes for the entire three-dimensional framework. [Symmetry codes: (ii) − x, + y, − z; (iii) − − x, + y, − z; (iv) −x, 3 − y, 1 − z.] |
