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-[kappa]O)([mu]₄-5-meth­oxy­benzene-1,3-di­carb­oxy­lato-[kappa]⁴O¹: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-BDC^2- anionic ligands and by one DMF O atom. The three-dimensional framework of (I) formed by the bridging MeO-m-BDC^2- ligands and the Mn^II atoms exhibits a pts topo­logical network when MeO-m-BDC^2- and Mn^II are viewed as four-connected nodes.
