(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.] |
