For (I), the doubly protonated BIM ligands link the POM anions to form (a) a one-dimensional supramolecular chain along the [01] direction and (b) a two-dimensional layer parallel to the ac plane. (c) These layers and chains cross each other to form a three-dimensional supramolecular network. [Symmetry codes: (i) x, y − 1, z + 1; (ii) −x + 1, −y + 1, −z + 1; (iii) x − 1, y, z; (iv) −x + 1, −y + 1, −z.] |
