在高压下合成了两种新的汞的三元氧化物HgTiO_3和HgPbO_3。这两种化合物具有菱面体结构，这可能是类似的高温铌酸锂结构。HgTiO_3的六方晶胞尺寸为a = 5.3781 μ m，c = 13.604 μ m，HgPb_3的六方晶胞尺寸为a= 5.7515 μ m，c = 14.534 μ m。从“单晶”X射线数据研究了HgTiO 3的结构。
Two new ternary oxides of mercury, HgTiO3and HgPbO3, have been prepared at high pressure. Both compounds possess rhombohedral structures which probably are similar to the high-temperature LiNbO3structure. The hexagonal cell dimensions for HgTiO3are a = 5.3781 Å andc= 13.604 Å; for HgPbO3,a= 5.7515 A andc= 14.534 Å. The structure of HgTiO3has been studied from “single” crystal X-ray data.
