Synthesis and characterization of nickel(II) and copper(II) tricyanomethanide complexes with tris(2-aminoethyl)amine as co-ligand

Two new transition metal tricyanomethanide (tcm) complexes with tris(2-aminoethyl)amine (trisaea) as co-ligand, {Ni(trisaea)(tcm)2] (1) and [Cu(tren)]3·(μ3-tren)·NO3·5tcm·2H2O (2), have been synthesized and structurally characterized. Magnetic susceptibility measurement indicates that there are weak ferromagnetic interactions in 1 (θ=1.17K, C=1.17cm3mol−1K) and 2 (θ=0.52K, C=1.35cm3mol−1K) respectively.
