Abstract

A new complex [Ni(μ‐NCS)(L)(NCS)]n 1 (L=N1, N3‐bis(4‐methoxylbenzyl)‐diethylenetriamine) was synthesized and characterized by X‐ray crystallography and magnetic measurement. Its structure consists of a mono‐μ1,3‐NCS− bridged 1D Ni(II) chain, in which the Ni(II) ion is in an octahedron configuration, with dien (diethylene triamine) moiety of L coordinating in meridional fashion. Via intra and interchain NH···SCN hydrogen bonds, a wave‐like 2D layer is assembled, which is further linked to the adjacent ones by weak interlayer π···π interactions to give a 3D network. Magnetic measurements show weak ferromagnetic coupling in 1. The J value obtained from the best fit of the experimental data is 2.65 cm−1. Its magnetic properties are discussed based on the structure.
