A novel trinuclear nickel(II) komplex with N,N,N´,N´´,N´´-pentamethyldiethylenetriamine (pmdien) and a trithiocyanurate(3-) (ttc3-) bridge of composition [Ni3(pmdien) 3(μ-ttc)](ClO4) 3 (1) was prepared. The X-ray crystal structure of 1 was determined, revealing the tris-N,S chelating mode of the trithiocyanurate bridge, forming a regular NiII3 core. A deformed trigonal bipyramidal arrangement of the central atoms was further achieved by coordination of tree pmdien N atoms. The complex show a ferromagnetic exchange interaction among the NiII magnetic center that is tuned by single-ion anisotropy and/or antisymetric exchange. The complex orders ferromagnetically at Tc=10K and exhibits spin-glass properties.
