| Popis: | A reinvestigation of the ternary system Mo–Ni–P has been established using X-ray diffraction, scanning electron microscopy, and electron probe microanalysis. This up-to-date system shows 10 ternary phosphides, which were mostly structurally characterized from X-ray powder or single-crystal data. Among these phosphides, three new ternary phases are reported for the first time: triclinic Mo8.58Ni7.42P6 (a=7.0079(4) A, b=7.0290(4) A, c=7.0308(4) A, α=68.893(3)°, β=73.196(3)°, γ=60.149(3)°, space group P 1 , new structure type), cubic Mo3Ni2P1.18 (a=10.846(2) A, space group F 4 3m, Mn3Ni2Si-type structure), and tetragonal Mo2.675Ni0.325P (a=9.733(1) A, b=4.7805(7) A, space group I 4 , Mo3P-type derivative structure). These phases were prepared from the elements by high-temperature annealing at 1350°C, and their crystal structures exhibit numerous strong metal–metal bonds in agreement with their metal-to-nonmetal ratio higher than 2.5. Indeed, in a general way, the phosphorus coordination number for Mo and Ni atoms is relatively small so that metallic arrangements as [Ni4] tetrahedra and [Mo6] octahedra can be considered as examples in the structures of Mo8.58Ni7.42P6 and Mo3Ni2P1.18, respectively. |
