The triclinic structure of the title compound, C6H8N+·H2PO4−, with three symmetry-independent structural units (Z′ = 3), is formed of separate organic and inorganic layers alternating along thebaxis. The building blocks of the inorganic layer are deformed H2PO4tetrahedra assembled into infinite ladders by short and hence strong hydrogen bonds. The anilinium cations forming the organic layer are not hydrogen bonded to one another, but they are anchored by four N—H...O crosslinks between the dihydrogen phosphate chains of adjacent ladders. Two H atoms of each –NH3group then form one normal and one bifurcated N—H...O hydrogen bond to the P=O oxygens of two tetrahedra of one chain, while the third H atom is hydrogen bonded to the nearest O atom of an adjacent chain belonging to another dihydrogen phosphate ladder.

The title compound, {(C6H14N)[CdBr3]} n , self-assembles into a layered structure consisting of alternating organic and inorganic layers, with the two Cd atoms on inversion centres. In the inorganic layer, octahedral CdBr6 units share faces to form a one-dimensional perhalometallate chain, which interacts with the ammonium groups of the cations through hydrogen bonds, forming a two-dimensional hydrogen-bonded sheet.

The title compound, C25H25N9O9·C16H36N+·H2PO4 − (I) or (C25H25N9O9)·(n-Bu4N+)·(H2PO4 −) (systematic name: 3-(4-nitrophenyl)-1,1-bis{2-[3-(4-nitrophenyl)ureido]ethyl}urea tetrabutylammonium dihydrogen phosphate), comprises a tris-urea receptor (R), a dihydrogen phosphate anion and a tetra-n-butylammonium cation. It crystallizes with two independent formula units in the asymmetric unit. The conformations of the two tris-urea receptors are stabilized by N—H...O and C—H...O intramolecular hydrogen bonds. Each dihydrogen phosphate anion has two O—H...O intermolecular hydrogen-bonding interactions with the other dihydrogen phosphate anion. Inversion-related di-anion units are linked by further O—H...O hydrogen bonds, forming a chain propagating along the a-axis direction. Each dihydrogen phosphate anion makes a total of four N—H...O(H2PO4 −) hydrogen bonds with two ureido subunits from two different tris-urea receptors, hence each tris-urea receptor provides the two ureido subunits for the encapsulation of the H2PO4 − hydrogen-bonded chain. There are numerous intermolecular C—H...O hydrogen bonds present involving both receptor molecules and the tetra-n-butylammonium cations, so forming a supramolecular three-dimensional structure. One of the butyl groups and one of the nitro groups are disordered over two positions of equal occupancy.

Reticular framework materials thrive on designability, but unexpected reaction outcomes are crucial in exploring new structures and functionalities. By combining “incompatible” building blocks, we employed geometric frustration in reticular materials leading to emergent structural features. The combination of a pseudo C<sub>5</sub> symmetrical organic building unit based on a pyrrole core, with a C<sub>4</sub> symmetrical copper paddlewheel synthon led to three distinct frameworks by tuning the synthetic conditions. The frameworks show structural features typical for geometric frustration: self-limiting assembly, internally stressed equilibrium structures and topological defects in the equilibrium structure, which manifested in the formation of a hydrogen bonded framework, distorted and broken secondary building units and dangling functional groups, respectively. The influence of geometric frustration on the CO<sub>2</sub> sorption behavior and the discovery of a new secondary building unit shows geometric frustration can serve as a strategy to obtain highly complex porous frameworks.

The title compound, C29H42N4O5·0.5H2O, comprises four structural units. A flexible propyloxy unit in agaucheconformation, with a –C(H2)—C(H2)—C(H2)—O– torsion angle of −64.32 (18)°, connects an isoxazole ring and an approximately planar phenyloxadiazole ring system [with a maxixmum devation of 0.061 (2) Å], which are oriented almost parallel to one another with a dihedral angle of 10.75 (7)°. Furthermore, a C11-alkyl chain with a terminal hydroxy group links to the 3-position of the isoxazole ringviaan amide bond. In the crystal, a half-occupancy solvent water molecule connects to a neighbouring moleculeviaan intermolecular O—H...O(water) hydrogen bond to the C11-alkyl chain hydroxy group.
