Description
Summary:	The 2D (4,4) network is based on tetranuclear [MnII4(O2C-C6H4-CO2)4(dmf)4(H2O)2] SBUs and consists of approximately rhombic prismatic cells. The layers are hydrogen bonded to 3D framework through the solvate molecules. Magnetic susceptibility studies revealed very weak exchange coupling between the MnII ions within the SBUs and no intralayer interactions. [Display omitted] A two-dimensional network [Mn4(O2C-C6H4-CO2)4(dmf)4(H2O)2]n·2n(dmf) (1·2n(dmf)) is reported. The repeating units in 1 consist of linear tetranuclear subunits [Mn4(O2C-C6H4-CO2)4(dmf)4(H2O)2] linked through the carboxylato groups of the terephthalato ligands. The layers of 1 extend parallel to the bc crystallographic plane and are further associated to 3D supramolecular network through hydrogen bonding interactions. Magnetic susceptibility studies from powdered samples of 1 revealed very weak exchange coupling between the MnII ions within the tetranuclear repeating unit.
