“…Here, we showed how antiferromagnetically coupled Mn(II) ions on the manganese dicarboxylate layers were affected when the packing of the layers was different as a consequence of H-bonding interactions. 19 In this work, we investigated an L-shaped ligand, benzophenone-2,4'dicarboxylic acid (2,4′-H 2 bpdc) with a few selected N-donor-based auxiliary ligands (Scheme 1) intending to explore the variation in the supramolecular aggregation of 1:1 manganese carboxylate building block. We aimed to examine how nonbonding interactions exerted by the auxiliary ligands further influenced supramolecular aggregation and hence the crystal packing.…”

“…When we opted for 4,4′-bpdc (benzophenone-4,4’dicarboxylate) wherein a carbonyl group replaced the sulfonyl in H 2 SBA, crystallization reaction of the system Mn(II)-4,4′- bpdc -solvent led to three isostructural solids, [Mn II (sol)(4,4′- bpdc )] where sol = H 2 O, DMF, or DMSO.

The role of the N-donor auxiliary ligand in the formation of coordination polymers (CPs) has been examined for a series of Mn(II) aromatic dicarboxylate-based framework systems. The solvothermal reaction of L-shaped dicarboxylate with Mn(II) through a varying N-donor auxiliary ligand resulted in the crystallization of six new multinuclear Mn-based CPs:MnCP6 (where 2,4′-bpdc = benzophenone-2,4′-dicarboxylate, phen = 1,10 phenanthroline, 2,2′-bipy = 2,2′-bipyridine, 4,4′-dimethyl-2,2′-bipy = 4,4′-dimethyl-2,2′-bipyridine, and 5,5′-dimethyl-2,2′-bipy = 5,5′-dimethyl-2,2′-bipyridine). The two 1D CPs, MnCP1 (square pyramidal) and MnCP2 (trigonal prism), respectively, were isolated from reactions in the absence and presence of an auxiliary ligand. The presence of phen led to anhydrous MnCP2 wherein C−H•••O interactions stabilized the 1D chains. The crystal packing in the hydrated MnCP1 is facilitated due to carboxylate oxygens interacting strongly with disordered lattice water. The auxiliary ligand, 2,2′-bipy and its derivatives in a suitable solvent led to the growth of four new solids built of a trimeric manganese cluster. MnCP3 is a layered solid while the methyl substituents on 2,2′-bipy altered the manganese carboxylate extended coordination in a different manner: (i) 4,4′-methyl substitution led to 1D (MnCP4) and 2D network (MnCP5); the bridging within the trimeric unit is also facilitated through in situ formed counter anions formate and acetate groups. (ii) 5,5′-Methyl substitution led to a 1D chain (MnCP6) where the trimeric unit occurred through the interference by another counter anion (chloride). The paper provides a mechanistic pathway for the observed crystal packing in terms of supramolecular condensation of soluble 1:1 manganese dicarboxylate complex species through a combination of coordination and H-bonding interactions. It also highlights how the supramolecular assembly is influenced when another competing soluble manganese complex coprecipitates, thus providing a rationale to the observed composition and coordination framework. All the manganese carboxylates showed antiferromagnetic behavior. The magnetic behavior of the two structurally comparable solids, MnCP1 and MnCP2, were further supported by highlevel first principle-based computations.

“…Structural chemistry of these three solids showed the dominance of manganese carboxylate interaction extending into two-dimension. The coordinated solvent molecules occupying the apical positions of the manganese polyhedra further altered the packing of these sheets and influenced the extent of antiferromagnetic interactions between the magnetic centers . Auxiliary ligands are commonly employed to impart alternate structural characteristics in CPs for target-specific applications. − They have affected crystallization pathways of CPs in various ways: (i) Neutral auxiliary ligand (e.g., 2,2′- bipy , phen ): generally blocked the coordinating site of the metal ion while ligands such as 4,4′- bipy pillared chains or sheets. ,− (ii) Ionic auxiliary ligands like lactic acid provided different coordination environments and thereby opened up new structural diversity. , An analysis of the structural landscape of the system Mn(II)-semirigid aromatic dicarboxylates with and without an auxiliary ligand revealed several interesting structural features (Table S1).…”

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.
