“…It should also be noted that the present type of topology is very rare, with only one example so far reported. 60 In particular, compound NH 2 -TMU-73 represents the first noninterpenetrated MOF of the xah topological type.…”

Carbon dioxide (CO2) fixation to generate chemicals and fuels is of high current importance, especially toward finding mild and efficient strategies for catalytic CO2 transformation to value added products. Herein, we report a novel Lewis acid–base bifunctional amine-functionalized dysprosium(III) metal–organic framework [Dy3(data)3·2DMF]·DMF (2,5-data: 2,5-diamino-terephthalate), NH2-TMU-73. This compound was fully characterized and its crystal structure reveals a 3D metal–organic framework (MOF) with micropores and free NH2 groups capable of promoting the chemical fixation of CO2 to cyclic carbonates. NH2-TMU-73 is built from the Dy(III) centers and data2– blocks, which are arranged into an intricate underlying net with a rare type of xah topology. After activation, NH2-TMU-73 and its terephthalate-based analogue (TMU-73) were applied for CO2-to-epoxide coupling reactions to produce cyclic carbonates. Important features of this catalytic process concern high efficiency and activity in the absence of cocatalyst, use of solvent-free medium, atmospheric CO2 pressure, and ambient temperature conditions. Also, NH2-TMU-73 features high structural stability and can be recycled and reused in subsequent catalytic tests. An important role of free amino groups and open metal sites in the MOF catalyst was highlighted when suggesting a possible reaction mechanism.

“…The sheets are further stabilized by C–H···O CO interaction (shown in yellow region) taking place between the carbonyl group of 4,4′- bpdc in one sheet and the phenyl group from adjacent sheet resulting in the overall supramolecular architecture (Figure ). Pillaring nature of 4,4′- bipy is commonly observed. , …”

Exploration of the structural landscape of the system Mn(II) salt−4,4′-benzophenone dicarboxylic acid−N-donor based auxiliary ligand−solvent using high-throughput solvothermal reaction led to the isolation of seven new coordination polymers (CPs): [Mn(phen)(H 2 O)(4,4′-bpdc) 2 ] 1, [Mn 3 (2,2′-bipy) 2 (4,4′-bpdc) 3 ]•solvent (solvent = DMA, DMF, and DMSO for 2, 3, and 4, respectively), [Mn 3 (4,4′-dimethyl-2,2′-bipy) 2 (4,4′-bpdcA single-crystal X-ray diffraction study revealed that the presence of phen led to solid 1 that contained 1D chains made of Mn(II)-carboxylate dimers. The auxiliary ligand 2,2′-bipy and its 4,4′-dimethyl derivatives in a suitable solvent led to the growth of the solids 2 and 5 with a trimeric manganese cluster, where the building block, 1:1 manganese carboxylate got extended into 2D sheet and 3D network, respectively. The ligand 2,2′-bipy with 5,5′-dimethyl substitution led to 1D anionic chains of the composition, [Mn(5,5′-dimethyl-2,2′-bipy)(4,4′-bpdc) 2 ] 2− , stabilized by the cationic complex, {Mn(5,5′dimethyl-2,2′-bipy)(H 2 O) 4 } 2+ in 6. As expected, the auxiliary ligand, 4,4′-bipy acted as a bridging unit to pillar 1D chains of manganese-carboxylate forming a 2D sheet in 7. Retro analysis of the various structures reported here provided a mechanistic approach not only to rationalize the crystal packing of manganese(II) 4,4′-benzophenone dicarboxylates but also to enhance the understanding of crystallization of manganese(II) 2,4′-benzophenone dicarboxylates and other related solids. We have also discussed the antiferromagnetic behavior of 1, 2, 5, and 7 in the context of other structurally related manganese(II) dicarboxylates.

“…The three-interpenetrated nets are related by a single translational vector (Class Ia) [24], with Zt = 3 and Zn = 1, where Zt represents the number of interpenetrated nets related by translation and Zn denotes the number of interpenetrated nets related by crystallographic symmetry [25]. To the best of our knowledge, this is the first example of 3D cobalt(II) coordination polymer with xah topology [26]. Compound 2 crystallizes in the triclinic space group Pī.…”

Two coordination polymers formulated as [Co 2 (2,6-ndc) 2 (L)] n (1) and [Ag(L)(1,4-Hndc)] n (2) (L = 1, 1 0 -(1,4-butanediyl)bis(2-methylbenzimidazole), 2,6-H 2 ndc = 2,6-naphthalenedicarboxylic acid, 1,4-H 2 ndc = 1,4-naphthalenedicarboxylic acid) were synthesized under hydrothermal conditions and characterized by IR, elemental analysis, and single-crystal X-ray diffraction. The structural analysis reveals that complex 1 exhibits an unprecedented 3D framework with threefold interpenetrating xah topology. Complex 2 shows a 1D ''X''-like chains bridged by L ligands, which is further extended via O-HÁÁÁO hydrogen bonding interactions into a 2D (4,4) supramolecular layer. The thermal stability and catalytic properties of two complexes for the degradation of Congo red dye in a Fenton-like process was also investigated.
