Synthesis and structure of a manganese(II) coordination polymer assembled with 5-(tert-butyl)isophthalic acid and 1,3-dimethyl-2-imidazolidinone

A manganese(II) coordination polymer [Mn(tbip)(DMI)] n ( 1 ), (tbipH 2 = 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 P 2 1 / 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.
