Helical bis[2-(ferrocenylmethyleneamino)benzenethiolato] metal(II) complexes (M = Ni, Zn or Pd) and a related mercury(II) complex
Abstract
The reaction between M2+(M = Ni, Zn or Pd) and 2-(ferrocenyl)benzothiazoline in ethanol affords the trinuclear complexes [M(fabt)2][fabt = 2-(ferrocenylmethyleneamino)benzenethiolate]. Interaction of [Ni(fabt)2] or [Zn(fabt)2] with HgCl2 gives the complex trans-[Hg(fabt)2]. Infrared, 1H NMR, electronic absorption and cyclic voltammetric data are given. The crystal structures of [Ni(fabt)2] and [Pd(fabt)2] show a helical geometry, which is also confirmed for distorted-tetrahedral [Zn(fabt)2].
