(a) The new coordination mode of the HY3− anion to K+ in (II) ; only ligating O atoms from symmetry-related anions in the coordination sphere of K1 are shown for clarity. (b) The coordination environment of K1 in (II) . (c) The coordination sphere of the K2 cation in (II) . (d) The environment of the HY3− anion. [Symmetry codes: (vi) −x + 1, −y + 2, −z + 1; (vii) x − 1, y, z; (viii) x, y, z + 1; (x) x, y + 1, z; (xi) −x, −y + 2, −z.] |
