✦ Synopsis

Abstract

The cover picture shows the three‐dimensional supramolecular arrangement of 1,10‐phenanthroline (phen) residues in compound (Hphen)~6~[Ge~6~(OH)~6~(hedp)~6~]·2(phen)·20H~2~O (where H~4~hedp stands for etidronic acid). Protonated organic residues, Hphen^+^, π‐π‐stack along the [101] direction of the unit cell, which leads to the formation of columns that are interconnected through a series of weak C–H···π interactions with neighbouring 1,10‐phenanthrolines. The resulting organic framework is highly porous and contains charge‐balancing centrosymmetric hexameric anionic [Ge~6~(ν~2~‐OH)~6~(C~2~H~4~O~7~P~2~)~6~]^6–^ moieties within the channels and a large number of highly disordered water molecules (total available volume of ca. 2462 Å^3^ per unit cell). Details are discussed in the article by J. Rocha et al. on p. 4741 ff.
