The reaction of cis- or trans-[Ru((BuNC)-Bu-t)(4)(CN)(2)] with MnCl2 as an additional transition metal fragment yields the one dimensional coordination polymers {cis-[Ru(CN)(2)((BuNC)-Bu-t)(4)] MnCl2}(n), (1), and {trans-[Ru(CN)(2)((BuNC)-Bu-t)(4)]MnCl2}(n), (2), with a different arrangement of the metal centers caused by the different stereochemistry of the starting compounds.

The variation of the Ru-C-N-Mn geometry nevertheless leads to significant differences in the magnetic properties of 1 and 2. The coordination polymer derived from trans-[Ru((BuNC)-Bu-t)(4)(CN)(2)] shows a more efficient antiferromagnetic intrachain interaction between the manganese centers compared to the cis-derivative. » weiterlesen» einklappen
