A three‐dimensional manganese(II) metal–organic framework based on 5‐methoxybenzene‐1,3‐dicarboxylic acid and exhibiting a pts net

The solvothermal reaction of MnCl₂·H₂O and 5‐methoxybenzene‐1,3‐dicarboxylic acid (MeO‐m‐H₂BDC) led to a three‐dimensional Mn^II metal–organic framework, namely poly(dimethylformamide‐κO)(μ₄‐5‐methoxybenzene‐1,3‐dicarboxylato‐κ⁴O¹:O^1′:O³,O^3′:O³)manganese(II)], Mn(C₉H₆O₅)(C₃H₇NO)]_n or Mn(MeO‐m‐BDC)(DMF)]_n (DMF is dimethylformamide). The Mn^II atom 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 Mn^II atoms exhibits a pts topological network when MeO‐m‐BDC²⁻ and Mn^II are viewed as four‐connected nodes.
