The solid-state reaction of caesium tetrachloronickelate(II) in caesium tetrachlorozincate(II)

Abstract

A solid-state reaction in the system Cs₂Ni–ZnCl₄ has been determined by magnetic, spectroscopic, and X-ray powder methods to be Cs₂NiCl₄+ Cs₂ZnCl₄→ CsNiCl₃+ Cs₃ZnCl₅. This reaction has been followed by the use of changing magnetic properties of the system. The reaction, which appears to be water catalysed and presumably diffusion controlled, is basically a solid-state polymerisation and its extent seems to be limited by the fact that one mole of Cs₂ZnCl₄ is able to stabilise ca. one sixth of a mole of Cs₂NiCl₄.
