The diploma thesis presents the crystal structures of four coordination compounds, consisting of a bipyridinium cation and a hexafluoridometallate anion. The following compounds are presented: 2,2’-bipyridinium hexafluoridotitanate, 4,4’-bipyridinium hexafluoridotitanate, 4,4’-bipyridinium hexafluoridostanate and 4,4’-bipyridinium hexafluoridohafnate. In the case of 2,2’-bipyridinium hexafluoridotitanate, only one nitrogen atom in the 2,2’-bipyridinium cation is protonated, and in the other three compounds both nitrogen atoms are protonated in the 4,4’-bipyridinium cations. In my thesis, I focused on the synthesis pathway and the results of X-ray structural analysis of each compound.
