Hydrogen-bonded supramolecular manganese(II) complexes with network and sheet structures bridged by terephthalate unit

Two hydrogen-bonded supramolecular assemblies, [Mn(4-methylpyrazole)3(H2O)(tp)]n with a 3D framework and [Mn(4-methylpyrazole)4(tp)]n (tp = terephthalate) exhibiting a 2D sheet structure, have been prepared and characterized by X-ray crystallography and magnetic measurements.
