| Abstract: | The reaction of Mn2+ with Cr(ox)3]3- in the presence of the spin-crossover Co(terpy)2]2+ cation gives rise to a 1D Co(terpy)2]Mn(H2O)ClCr(ox)3].H2O.0.5MeOH (1) or a 2D Co(terpy)2]Mn(H2O)Cr(ox)3]2.5H2O.0.5MeOH (2). The trimetallic complexes display dominant ferromagnetic behavior, and spin-crossover of Co(terpy)2]2+ is suppressed by the chemical pressure of the polymeric oxalate-bridged network. |
