“…We must first notice that the water uptake is high for this compound and that the reached value [0.230 g(H 2 O) per g] is very close to the expected one if the initial hydrated phase is recovered [0.233 g(H 2 O) per g for 12 H 2 O per Cu]. It is worth noting that this water content is considerably higher than the amounts reported for other PSN (0.1–0.15 g per g) , , . The maximum uptake observed for Cu( pc1 ) 2 Cl 2 is thus comparable with the capacity of 3A molecular sieves (0.22 g per g) .…”

The rigid zwitterionic ligand 1,1′‐bis(4‐carboxylatphenyl)‐(4,4′‐bipyridinium) (pc1) and copper(II) ions give rise to a linear complex [Cu(pc1)2(H2O)4]2+, which self assembles in a pseudo tetragonal supramolecular arrangement leading to the supramolecular open‐framework [Cu(pc1)2(H2O)4](Cl)2·8H2O exhibiting an open structure including water molecules and chlorides in pores. The dehydration of this material occurs at relatively low temperature (70 °C) and results in structure modification accompanied by shrinking of the crystals. Characterization of the obtained material by FT‐IR spectroscopy reveals appearance of coordinated carboxylates groups, which may indicate the formation of coordination polymer after dehydration. Water adsorption (maximum uptake 0.23 g H2O per g) on dehydrated material allows to restore the initial structure. A large hysteresis in water adsorption‐desorption isotherm is characteristic of a significant modification of the structure during the hydration‐dehydration cycle which is in line with the structural transition determined from thermodiffractometry and FT‐IR spectroscopy.

From aqueous solutions containing Λ-[Co(en) 3 ]I 3 (1, 2), Δ-[Co-(en) 3 ]I 3 (5), or racemic [Co(en) 3 ]I 3 (3, 4) AgI and PbI 2 respectively were precipitated by addition of Ag 2 EDC, [Ag(en)][Ag(BDC)], PbADC or (NH 4 )[Ag 5 (BTC) 2 (NH 3 )-(H 2 O) 2 ] and filtered off (en = ethylenediamine, H 2 EDC = fumaric acid, H 2 BDC = terephthalic acid, H 2 ADC = acetylenedicarboxylic acid, H 3 BTC = trimesic acid). After slow evaporation of the remaining solutions single crystals of ∞ 1and ∞ 2 {Δ-[Co(en) 3 ]EDC(NO 3 )}•2H 2 O (C2, Z = 4, 5) were obtained. In all compounds the [Co(en) 3 ] 3+ cores are connected in a T-shaped mode via N−H•••O hydrogen bonds to the carboxylates to form complex networks. Water molecules are bound via O−H•••O hydrogen bonds to the networks, further increasing their complexity. It is noteworthy that the chirality of the starting material (Λ-or Δ-[Co(en) 3 ]I 3 ) is maintained during the reaction thus leading to non-centrosymmetric polymers, whereas with racemic [Co(en) 3 ]I 3 centrosymmetric polymers are obtained.

“…[44][45] The same approach can be implemented with ionic metal complexes. [46][47][48] Several examples of openframework architectures, [49][50][51] including some porous frameworks, [39,[52][53][54][55] have been reported. Along this line, our approach involves negatively-charged metal complexes, such as metal-oxalate or analogues, acting as H-bond acceptors [56][57] towards H-bond donor organic cations to form networks underpinned by robust and reliable supramolecular synthons.…”

Five isostructural microporous supramolecular architectures prepared by H-bonded assembly between the hexa-anionic complex [Zr 2 (Ox) 7 ] 6À (Ox = oxalate, (C 2 O 4 ) 2À ) and tripodal cations (H 3 -TripCH 2 -R) 3 + with R = H, CH 3 , OH and OBn (Bn = CH 2 Ph) are reported. The possibility to obtain the same structure using a mixture of tripodal cations with different R group (R = OH and R = CH 3 ) has also been successfully explored, providing a unique example of three-component Hbonded porous framework. The resulting SPA-1(R) materials feature 1D pores decorated by R groups, with apparent pore diameters ranging from 3.0 to 8.5 Å. Influence of R groups on the sorption properties of these materials is evidenced through CO 2 and H 2 O vapor sorption/desorption experiments, as well as with I 2 capture/release experiments in liquid media. This study is one of the first to demonstrate the possibility of tuning the porosity and exerting precise control over the chemical functionalization of the pores in a given H-bonded structure, without modifying the topology of the reference structure, and thus finely adjusting the sorption characteristics of the material.
