Structure and magnetic properties of a trinuclear nickel(II) complex with benzenetricarboxylate bridge
Journal article, 2008

Novel trinuclear Ni(II) complex [Ni3(pmdien)3(btc)(H2O)3](ClO4)3·4H2O, 1 where pmdien = N,N,N′,N′,N″-pentamethyldiethylenetriamine, H3btc = 1,3,5-benzenetricarboxylic (trimesic) acid, has been prepared and structurally characterized. Three nickel atoms are bridged by btc trianion and their coordination sphere is completed by three N atoms of pmdien and O atom of the water molecule. The three nickel(II) magnetic centers are equivalent and their coordination spheres are completed to deformed octahedrons. Magnetic susceptibility was measured over the temperature range 1.8–300 K and zJ′ = −0.19 cm−1, D = 3.79 cm−1, g = 2.18 parameters were calculated.
