“…All these compounds are characterized by the presence of isolated chains of magnetic ions ðBF 5 Þ 2nÀ n [6]. Synthesis, crystal structure and magnetic susceptibility measurements on CaTiF 5 (s) and BaTiF 5 (s) have been carried out by Eicher and Greedan [6], in order to establish a model system for studying low dimensional magnetic interactions involving ðBF 5 Þ 2nÀ n chains. According to Eicher and Greedan [6], CaTiF 5 is isostructural with CaCrF 5 with monoclinic unit cell and space group I2/c.…”
