Diammine nickel(II) halides, Ni(NH 3 ) 2 X 2 (X β«Ψβ¬ Cl, Br, I), were prepared by decomposition of the corresponding hexaammines at 1203C in dynamical vacuum. Their crystal structures are of the Cd(NH 3 ) 2 Cl 2 type (99 -type::, space group Cmmm, Z β«Ψβ¬ 2): for Ni(NH 3 ) 2 Cl 2 , a β«Ψβ¬ 8.019 A s , b
Zr 2 Ni 2 In and Zr 2 Ni 2 Sn were prepared from the elements by a reaction in an arc melting furnace and subsequent annealing at 1070 K. They crystallize with the tetragonal Er 2 Au 2 Sn-type structure of space group P4 2 /mnm, a ternary ordered version of the Zr 3 Al 2 -type. Both structures were
