Two new compounds were synthesized by heating mixtures of the elements at 975-1025 K and characterized by single-crystal X-ray methods. CaZn 2 Si 2 (a=4.173(2) ( A, c=10.576(5) ( A) and EuZn 2 Ge 2 (a=4.348(2) ( A, c=10.589(9) ( A) crystallize in the ThCr 2 Si 2 -type structure (space group I4/mmm;
An ampule reaction between Mo and PCl 5 at 200 Β°C yielded (PCl 4 ) 2 [Mo 2 Cl 10 ], the first ternary compound in MoΒ±PΒ±Cl system. Single crystal X-ray diffraction gave a triclinic unit cell: a = 6.870(1), b = 8.892(2), c = 9.423(2) A Γ , Ξ± = 100.24(2), b = 95.55(2), c = 96.12(2)Β°(V = 559.3(2) A Γ 3
