Spontaneous magnetization in [1-(4-cyanobenzyl)pyridinium][Pt(mnt)_2]: synthesis, crystal structure and magnetic property

摘要

a new complex [1-(4-cyanobenzyl)pyridinium][Pt(mnt)_2] (1), in which mnt~(2+) = maleonitriledithiolate, has been prepared and characterized. In the solid state, anions and cations of 1 form completely segregated stacking column, and the [Pt(mnt)_2]~- anion column behaves as one-dimensional (1-D) spaced magnetic chains. 1 spontaneously magnetizes at low temperatures, which may arises from spin canting.
