“…The coordinated solvent appeared to exert a strong influence on dictating the packing of the 2D manganese carboxylate sheets through varying H-bonding interaction and probably resulted in the variation noticed in the AFM interaction. Effect of solvent on the synthesis of CPs has been reported in a few cases. − To our knowledge, this is the first paper that provides a comparative study of the influence of solvent on the crystal packing of compositionally identical solids viz., [Mn(sol)( bpdc )] and its impact on the magnetic property. Here, we report synthesis, structural characterization, and magnetic properties of the three new solids.…”

Three new isostructural manganese coordination polymers, [Mn(H 2 O)(bpdc)] (1), [Mn(DMF)(bpdc)] (2), and [Mn-(DMSO)(bpdc)] (3) (bpdc = benzophenone-4,4′-dicarboxylate), have been successfully crystallized employing solvent variation. A single crystal X-ray diffraction study revealed that the three solids built of manganese polyhedron (square pyramidal in 1 and octahedral in 2 and 3) extended into two-dimensional sheets through manganese carboxylate coordination interaction. The packing of the layers, however, was greatly influenced through hydrogen bonding exerted by the coordinated solvent molecules (H 2 O, DMF, and DMSO) occupying the apical position of the manganese polyhedron. Low-temperature antiferromagnetic interactions arising due to coupling between the adjacent Mn 2+ ions showed a strong correlation with the variation in the packing of the layers. First-principles calculations of the electronic structures of the solids in terms of singlet (S = 0 with Noodleman's Broken Symmetry) and triplet (S = 1) states showed the superexchange interaction energies to be −0.24, −0.12, and −0.18 eV, respectively, for 1, 2, and 3; the magnetic exchange coupling variation is in correspondence with the decrease in H-bonding interaction holding the layers: H 2 O < DMSO < DMF. The paper also postulates a mechanistic pathway for the observed crystal packing in terms of supramolecular condensation of 1:1 manganese dicarboxylate complexes through a combination of coordination and H-bonding interactions.

“…In this context, small changes on the synthetic conditions inter alia starting metal salt or precursor, metal–ligand ratio, temperature, or solvent can lead to the obtention of different CPs. In addition, their possible structural transformations triggered by external stimuli (e.g., solvent, light, heat, or synergic effects , ) have attracted remarkable attention, paving the way for the obtention of new structures inaccessible through other synthetic methods. − Besides, when these transformations show a reversible behavior, the CPs display promising applications in molecular capture, switches, and so on . Typically, these transformations are sorted into two groups, namely, solid-state structural transformations (SSSTs) and dissolution–recrystallization structural transformations (DRSTs) .…”

The behavior of coordination polymers (CPs) against external stimuli has witnessed remarkable attention, especially when the resulting CPs present reversible molecular arrays. Accordingly, CPs with these characteristics can lead to differences in their properties owing to these structural differences, being promising for their use as potential molecular switches with diverse applications. Herein, we have synthesized four Zn(II) CPs bearing α-acetamidocinnamic acid (HACA) and 4,4′-bipyridine (4,4′-bipy). The reaction between Zn(OAc) 2 •2H 2 O, HACA, and 4,4′-bipy yields {[Zn(ACA) 2 (4,4′-bipy)]•EtOH} n (1), which was used for the formation of three CPs through dissolution− recrystallization structural transformations (DRSTs, and {[Zn 3 (μ-ACA) 6 (4,4′-bipy)]• 0.75CHCl 3 } n (4). The study of the four crystal structures revealed that their secondary building units (SBUs) comprise monomeric, dimeric, and trimeric arrangements linked by 4,4′-bipy ligands. The fundamental role of the utilized solvent and/or temperature, as well as their effect on the orientation of the amide moieties driving the formation of the different SBUs is discussed. Furthermore, the reversibility and interconversion between the four CPs have been assayed. Finally, their solid-state photoluminescence has evinced that the effect of the amide moieties not only predetermine a different SBU but also lead to a different emission in 4 compared with 1−3.

Reversible solvent‐triggered single‐crystal‐to‐single‐crystal (SCSC) transformations are observed between two copper(II) azamacrocyclic complexes: [Cu(C16H38N6)(H2O)2](C12H6O4) (1) and [Cu(C16H38N6)(C12H6O4)] (2). Complex (1) was prepared via self‐assembly of a copper(II) azamacrocyclic complex containing butyl pendant groups, [Cu(C16H38N6)(ClO4)2], with 2,7‐naphthalenedicarboxylic acid. When monomeric compound (1) was immersed in CH3OH, coordination polymer (2) was obtained, indicating a solvent‐triggered SCSC transformation. Furthermore, when (2) was immersed in water, an reverse SCSC transformation from (2) to (1) occurred. Complex (1) presents a 3D supramolecular structure formed via intermolecular hydrogen‐bonding interactions, whereas complex (2) features a 1D zigzag coordination polymer. The reversible SCSC transformation of (1) and (2) was characterized using single‐crystal X‐ray diffraction and in situ powder X‐ray diffraction techniques. Despite its poor porosity, complex (2) displayed interesting CO2 adsorption behaviour under CO2 gas.
