New oxalate-bridged Cr-III-Mn-II polymeric network incorporating a spin-crossover [Co(terpypy)(2)](2+) cation
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)]center dot H2O center dot 0.5MeOH (1) or a 2D [Co(terpy)(2)][Mn(H2O)-Cr(ox)(3)](2)center dot 5H(2)O center dot 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.
