The solvothermal reaction of MnCl2·H2O and 5-methoxybenzene-1,3-dicarboxylic acid (MeO-m-H2BDC) led to a three-dimensional MnIImetal–organic framework, namely poly[(dimethylformamide-κO)(μ4-5-methoxybenzene-1,3-dicarboxylato-κ4O1:O1′:O3,O3′:O3)manganese(II)], [Mn(C9H6O5)(C3H7NO)]nor [Mn(MeO-m-BDC)(DMF)]n(DMF is dimethylformamide). The MnIIatom is six-coordinated and exhibits a distorted octahedral geometry formed by five carboxylate O atoms from four different MeO-m-BDC2−anionic ligands and by one DMF O atom. The three-dimensional framework of (I) formed by the bridging MeO-m-BDC2−ligands and the MnIIatoms exhibits aptstopological network when MeO-m-BDC2−and MnIIare viewed as four-connected nodes.

Organic Framework

A polydentate ligand bridged by a fluorene group, namely 9,9-bis(2-hydroxyethyl)-2,7-bis(pyridin-4-yl)fluorene (L), has been prepared under solvothermal conditions in acetonitrile. Crystals of the three-dimensional metal–organic framework (MOF) poly[[[μ3-9,9-bis(2-hydroxyethyl)-2,7-bis(pyridin-4-yl)fluorene-κ3 N:N′:O]bis(methanol-κO)(μ-sulfato-κ2 O:O′)nickel(II)] methanol disolvate], {[Ni(SO4)(C27H24N2O2)(CH3OH)]·2CH3OH} n , (I), were obtained by the solvothermal reaction of L and NiSO4 in methanol. The ligand L forms a two-dimensional network in the crystallographic bc plane via two groups of O—H...N hydrogen bonds and neighbouring two-dimensional planes are completely parallel and stack to form a three-dimensional structure. In (I), the NiII ions are linked by sulfate ions through Ni—O bonds to form inorganic chains and these Ni-containing chains are linked into a three-dimensional framework via Ni—O and Ni—N bonds involving the polydentate ligand L. With one of the hydroxy groups of L coordinating to the NiII atom, the torsion angle of the hydroxyethyl group changes from that of the uncoordinated molecule. In addition, the adsorption properties of (I) with carbon dioxide were investigated.

Organic Framework

Over the past two decades, the development of novel inorganic–organic hybrid porous crystalline materials or metal–organic frameworks (MOFs) using crystal engineering has provoked significant interest due to their potential applications as functional materials. In this context, luminescent MOFs as fluorescence sensors have recently received significant attention for the sensing of ionic species and small molecules. In this work, a new luminescent heterometallic zinc(II)–barium(II)-based anionic metal–organic framework, namely poly[imidazolium [triaqua(μ6-benzene-1,3,5-tricarboxylato)bariumtrizinc] tetrahydrate], {(C3H4N2)[BaZn3(C9H3O6)3(H2O)3]·4H2O} n (1), was synthesized under hydrothermal conditions and characterized. Compound 1 presents a three-dimensional framework with an unprecedented (3,5)-connected topology of the point symbol (3.92).(33.42.5.93.10), and exhibits `turn-off' luminescence responses for the Cu2+ and Fe3+ ions in aqueous solution based on significantly different quenching mechanisms.
