Ferromagnetic Properties of a Trinuclear Nickel(II) Complex with a Trithiocyanurate Bridge
Journal article, 2009

A novel trinuclear nickel(II) complex 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 triangular NiII3 core. A deformed trigonal bipyramidal arrangement of the central atoms was further achieved by coordination of three pmdien N atoms. The complex shows a ferromagnetic exchange interaction among the NiII magnetic centers that is tuned by single-ion anisotropy and/or antisymmetric exchange. The complex orders ferromagnetically at Tc = 10 K and exhibits spin-glass properties.
