Copper(II) and Manganese(II) Coordination Polymers of 5‐Aminobenzene‐1,3‐dicarboxylic Acid (abdc) Ligand, Structural Studies of [Cu(μ4‐abdc) (DMF)]n and {[Mn(μ4‐abdc)(H2O)]·H2O}n

Two new two-dimensional CuII and MnII coordination polymers of 5-aminobenzene-1,3-dicarboxylic acid (abdc) ligand, [Cu(μ4-abdc)(DMF)]n and {[Mn(μ4-abdc)(H2O)]·H2O}n, have been synthesized and characterized by elemental analysis and IR- spectroscopy. The single crystal X-ray analyses show that the coordination number in these complexes is six, CuO5Cu and MnO5N. The compounds are structurally diverse and the coordination polymer obtained from copper show significant copper–copper interaction while the manganese coordination polymer shows Mn–Namino bond.
