Artykuł
A new complex [Ni(L)Fe(CN)5NO] · 2H2O (L = 4,6,6-trimethyl-1,9-diamino-3,7-di-aza-nona-3-ene) has been obtained and characterized by means of X-ray crystallographic analysis and magnetochemistry. The Fe(CN)5NO2− anion links to the Ni(L)2+ cation through two bridging cyanide groups in a bent fashion. The intrachain Ni⋯Ni and interchain Ni⋯Ni distances are equal to 9.81(8) and 7.75(1) Å, respectively. The magnetic behaviour of the complex indicates the zero field splitting parameter D higher than 3 cm−1 and the average exchange parameter (intra- and interchain) corresponding to direct Ni–Ni magnetic interaction in the crystal lattice equals ∼−0.2 cm−1.
