Abstract : Zirconium triiodide and hafnium triiodide were prepared by aluminum reductions of the corresponding tetrahalides. Green and black species of both compounds were isolated. The magnetic susceptibilities of these compounds were measured over the temperature range 100?-300 K by the Gouy method. A correlation of observed magnetic and structural properties is given in terms of competing ferromagnetic and antiferromagnetic interactions in the lattice. The visible absorption spectrum was measured for species obtained on dissolution of zirconium triiodide in water. Absorption bands were assigned for what is proposed to be the hexaquozirconium ion and a less stable iodinated species of the aquozirconium ion. (Author)
