Figure 3
(a) The zigzag ribbons along the b axis formed by the H2P2O62− anions in (II), joined by O—H⋯O hydrogen bonds (blue dashed lines in the electronic version of the paper), held together via water-bridged ribbon⋯water⋯ribbon inter­actions (orange dashed lines). (b) The architecture of a layer parallel to (10[\overline{1}]) formed by anionic ribbons connected via dimers of edge-shared [KO7] polyhedra based on K1, viz. [K2O12] (dark blue). (c) Two anionic–cationic layers joined to each other via chains of edge-shared [K2O7] polyhedra (light blue), running down the b axis, and water-mediated hydrogen bonds. [Symmetry codes: (vii) −x + [{3\over 2}], y − [{1\over 2}], −z + [{3\over 2}]; (viii) −x + 2, −y + 1, −z + 1.]
