Two metal-rich compounds, Pd₅InP and Pt₅InP, were synthesized as phase-pure powders using a high-temperature ampoule technique. According to the Rietveld analysis, they crystallize in the fairly rare Pd₅TlAs structure type (tetragonal system, P4/mmm space group, Pearson symbol tP7, with a = 3.9303(5) Å, c = 6.9269(1) Å, Z = 1, R_p = 0.029, R_b = 0.004 for Pd₅InP, and a = 3.9500(1) Å, c = 6.9814(3) Å, Z = 1, R_p = 0.034, R_b = 0.005 for Pt₅InP. For both compounds, main structural units are indium-centered [TM₁₂In] cuboctahedra (TM=Pd, Pt), alternating along the c axis with [TM₈P] rectangular prisms of the PtHg₂ type. DFT electronic structure calculations and magnetic measurements indicate 3D metallic conductivity and diamagnetic behavior for both compounds. According to the bonding analysis based on the electron localizability indicator topology and charge density, both compounds are intermetallic in nature and feature four-centered interactions of the 3TM+In type between the transition metal and indium atoms in their heterometallic fragments, complemented in the case of platinum by Pt-Pt pairwise interactions. Both compounds do not show any significant hydrogen uptake up to pressures of ca. 7 MPa and temperatures of 700 K.

使用高温安瓿瓶技术将两种富含金属的化合物Pd ₅ InP和Pt ₅ InP合成为纯相粉末。根据Rietveld分析，它们以相当罕见的Pd ₅ TlAs结构类型（四方晶系，P 4 / mmm空间群，Pearson符号tP7）结晶，其中a = 3.9303（5）Å，c = 6.9269（1）Å，Z  = 1，R _p = 0.029，对于Pd ₅ InP ，R _b = 0.004 ，a = 3.9500（1）Å，c = 6.9814（3）Å，Z  = 1，R _p = 0.034，R _b对于Pt ₅ InP = 0.005 。对于这两种化合物，主要结构单元都是以铟为中心的[TM ₁₂ In]立方八面体（TM = Pd，Pt），沿c轴与PtHg ₂类型的[TM ₈ P]矩形棱柱交替排列。DFT电子结构计算和磁测量表明这两种化合物的3D金属电导率和抗磁性能。根据基于电子定位性拓扑和电荷密度的键合分析，这两种化合物本质上都是金属间化合物，并具有过渡金属与铟原子之间3TM + In型的四中心相互作用在它们的异金属片段中，在铂的情况下通过Pt-Pt成对相互作用来补充。两种化合物在约200 MPa的压力下均未显示任何显着的氢吸收。7 MPa，温度700K。
