Abstract: | On the First Alkaline Earth Mercurato(II)-Palladate(II, IV): Ba2Hg3Pd52+Pd24+O14 Single crystals of Ba2Hg3Pd7O14 were prepared by oxygen high-pressure technique (3900 bar) and investigated by X-ray technique. It crystallizes with monoclinic symmetry, space group C –C2/m; Z = 2 (a = 10.583; b = 6,207; c = 10.919 Å, β = 90.56°). The Hg2+ ions show partially dumb-bell like and one sided 3 fold coordination respectively. Pd4+ /Pd2+ show an octahedric or square planar surrounding. |
