Three bridged squarato 1-dimensional polymeric M(II) complexes were synthesized and structurally characterized: {[Cu2(LBDPA)(μ1,2-C4O4)(H2O)](ClO4)2·2H2O}n (1), {[Mn(DPA)(μ1,2-C4O4)(H2O)]·2H2O}n (2) and {[Zn(DPA)(μ1,3-C4O4)(H2O)]·2H2O}n (3) where LBDPA = 2,6-bis[bis(2-pyridylmethyl)aminomethyl]pyridine (LBDPA), DPA = bis(2-pyridylmethyl)amine, C4O2-4 = squarate dianion. Also, attempts were made to solve the x-ray structure of [Cd(Mepea)(μ1,2-C4O4)(H2O)]n (4) (Mepea = N-methyl-(2-pyridylmethyl)-(2-(2-pyridyl)ethyl)amine). The C4O2-4 dianions are bridging the M2+ centers via bis(monodentate) μ1,2-(cis) or μ1,3-(trans) bonding modes. Complex 1 reveals very weak antiferromagnetic coupling between the Cu(II) ions.
