Crystal Structure and Vibrational Spectra of [Ru(NH₃)₄(OH)(NO)] ZnCl₄

Abstract

The crystal structure of [Ru(NH₃)₄(OH)(NO)]ZnCl₄ was determined by X-ray diffraction methods. Such study confirmed the already reported data for the complex cation and allowed a description of the main features of the lattice structure. An infrared and Raman study of that compound was also performed in order to revise the existing assignment of the vibrational bands. This last study, backed by quantum chemical calculations, lead to a reinterpretation of the spectra. Data were also collected on the structural and vibrational characteristics of the ZnCl₄²⁻ anion. The X-ray structure of the title compound was determined. An infrared and Raman study of the substance was also performed and the data interpreted with the aid of theoretical calculations.
