A manganese(II) coordination polymer [Mn(tbip)(DMI)] n (1), (tbipH2 = 5-(tert-butyl)isophthalic acid, DMI = 1,3-dimethyl-2-imidazolidinone), has been synthesized under “urea-thermal conditions” (i.e. in an excess of urea). Its structure has been determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis and IR spectra. Complex 1 crystallizes in the monoclinic space group P21/c with Z = 4. In 1, the [tbip]2− ligand bridges the Mn(II) cations to form infinite chains, and the neighbouring chains are connected through [tbip]2− ligands into layers.
