(a) View of the coordination chains with hydrogen-bond interactions between pairs of symmetry-related aqua ligands that afford layers parallel to the ab plane. The Li+ ions are represented by coordination tetrahedra, while considering only the four shortest coordination bonds. (b) Projection of the structure on the ab plane with two successive layers indicated in blue and red. (c) Packing of the coordination chains following a Lincoln log pattern. The chain nodes represent the dilithium units and the chain links are bridging {TNBPz}2− anions. [Symmetry code: (vii) −x + , −y + , z.] |
