HF molecules and poly(hydrogen fluoride) anions as ligands to metal centers

Abstract

The paper is dealing with the two sets of the coordination compounds: (a) the coordination compounds in which anhydrous HF is acting as a ligand to the metal ions (b) the compounds in which poly(hydrogen–fluoride) anions of the type H n F n+1 − ( n = 1, 2, 3) are coordinated to the metal centers and connecting them in the 3D structures. The main purpose of this work is the review of the above mentioned compounds which were recently isolated in our laboratory. The coordination of the metal centers and their connection in the three-dimensional network are illustrated with their crystal structures. A very brief review of the achievements of some other groups is also mentioned where it is appropriate.
