The compounds [TeI 3 ][MI 4 ] (M = Ga, In) were obtained as air sensitive black crystals by the reactions of Te, I 2 and Ga or In in vacuum sealed ampoules. The gallium compound crystallizes in the structural type of [SCl 3 ][AlCl 4 ]: monoclinic system, space group Pc (No. 7), a = 7.211(11), b = 7.
The anhydrous rubidium tetraacetato lanthanate, RbLa(CH 3 COO) 4 , is obtained together with Rb 2 La(CH 3 COO) 5 (H 2 O) as colourless single crystals from a 1 : 2 mixture of Rb 2 CO 3 and La(CH 3 COO) ´1.5 H 2 O in acetic acid by slow evaporation. The crystal structure [orthorhombic, Pnnm, Z = 2, a
