Reticular synthesis, topological studies and physicochemical properties of a 3D manganese(II) coordination network [Mn3(BTC)2(DMSO)4]n Flores, Leonã da Silva Rosa, Roselia Ives Martins, Jefferson da Silva Pinho, Roberto Rosas Diniz, Renata Corrêa, Charlane Cimini Manganese Trimesic acid Reticular synthesis Coordination polymer Coordination network Secondary building unit In order to build a metal-organic framework with mixed ligands (acid-acid), a 3D coordination network based on manganese metal center was obtained [Mn3(BTC)2(DMSO)4]n; where BTC = Benzene-1,3,5-tricarboxylic acid and DMSO = Dimethylsulfoxide. The crystal structure was determined by single crystal X-ray diffraction, showing the assembly of a tridimensional 3,6-connected non-entangled polymeric network, with RTL topology. The secondary building unit (SBU) acts as a node of the 3-periodic expansion and involves carboxylate- and oxo-bridged metals. The DMSO employed in the synthesis is chemically involved in the coordination as a µ2-O bridge between distinct manganese metal centers. The structural characterization of the material was supported by spectroscopic (infrared absorption and Raman scattering), thermal (TG, DTG, and DTA) and elemental analysis.
