Abstract

Three binary -structured alloys (-IrPt, -RhPt and -RhPd) were prepared from [Ir(NH)Cl][PtCl], [Ir(NH)Cl][PtBr], [Rh(NH)Cl][PtCl]Cl and [Rh(NH)Cl][PdCl]·HO, respectively, as single-source precursors. All alloys were prepared by thermal decomposition in gaseous hydrogen flow below 800 °C. -IrPt and -RhPd correspond to miscibility gaps on binary metallic phase diagrams and can be considered as metastable alloys. Detailed comparison of [Ir(NH)Cl][PtCl] and [Ir(NH)Cl][PtBr] crystal structures suggests that two isoformular salts are not isostructural. In [Ir(NH)Cl][PtBr], specific Br…Br interactions are responsible for a crystal structure arrangement. Room temperature compressibility of -IrPt, -RhPt and -RhPd has been investigated up to 50 GPa in diamond anvil cells. All investigated -structured binary alloys are stable under compression. Atomic volumes and bulk moduli show good agreement with ideal solutions model. For -IrPt, / = 14.597(6) Å·atom, = 321(6) GPa and ' = 6(1); for -RhPt, / = 14.211(3) Å·atom, =259(1) GPa and ' = 6.66(9) and for -RhPd, / = 14.18(2) Å·atom, =223(4) GPa and ' = 5.0(3).

摘要

三种二元结构合金（-IrPt、-RhPt和-RhPd）分别由[Ir(NH)Cl][PtCl]、[Ir(NH)Cl][PtBr]、[Rh(NH)Cl][PtCl]Cl和[Rh(NH)Cl][PdCl]·HO作为单源前驱体制备而成。所有合金均通过在800℃以下的氢气气流中热分解制备。-IrPt和-RhPd对应于二元金属相图上的混溶间隙，可被视为亚稳合金。对[Ir(NH)Cl][PtCl]和[Ir(NH)Cl][PtBr]晶体结构的详细比较表明，两种同分子式盐并非同构。在[Ir(NH)Cl][PtBr]中，特定的Br…Br相互作用导致了晶体结构排列。在金刚石对顶砧中研究了-IrPt、-RhPt和-RhPd在室温下至50 GPa的压缩性。所有研究的-结构二元合金在压缩下都是稳定的。原子体积和体模量与理想溶液模型吻合良好。对于-IrPt，/ = 14.597(6) Å·原子， = 321(6) GPa，' = 6(1)；对于-RhPt，/ = 14.211(3) Å·原子， = 259(1) GPa，' = 6.66(9)；对于-RhPd，/ = 14.18(2) Å·原子， = 223(4) GPa，' = 5.0(3)。
