The interaction between the components of the ternary Y–Ni–P system has been investigated by means of electron probe microanalysis, X-ray phase and structure analyses, and the isothermal section of the phase diagram at 1070 K has been constructed for the first time. Existence of the earlier reported eight ternary phosphides of yttrium and nickel was confirmed, among them seven ternaries are daltonide compounds: YNi{sub 4}P{sub 2} (ZrFe{sub 4}Si{sub 2}-type structure), Y{sub 2}Ni{sub 12}P{sub 7} (Zr{sub 2}Fe{sub 12}P{sub 7}-type structure), Y{sub 6}Ni{sub 20}P{sub 13} (Zr{sub 6}Ni{sub 20}P{sub 13}-type structure), Y{sub 6}Ni{sub 14.9}P{sub 10.18} (own structure type), Y{sub 20}Ni{sub 42}P{sub 30.34} (Sm{sub 20}Ni{sub 41.6}P{sub 30}-type structure), Y{sub 15}Ni{sub 28}P{sub 21} (Tb{sub 15}Ni{sub 28}P{sub 21}-type structure), and YNiP (Tb{sub 1−x}NiP-type structure), whereas YNi{sub 1.66−1.78}P{sub 2} (ThCr{sub 2}Si{sub 2}-type structure) is a berthollide compound with small homogeneity range. The crystal structures of the some ternary phosphides have been determined by X-ray powder diffraction (YNi{sub 4}P{sub 2} and YNi{sub 1.66−1.78}P{sub 2}) and single crystal diffraction (Y{sub 2}Ni{sub 12}P{sub 7}) techniques. - Graphical abstract: Structure block with the composition Ln{sub 10}M{sub 21}X{sub 15} of the homologous series of the compounds (Ln,M){sub ∼2}X. Display Omitted - Highlights: • The phase diagram of Y–Ni–P at 1070 K has been constructed. • Existence of the eight ternary phosphides of yttrium and nickel has been confirmed. • The crystal structures of YNi{sub 4}P{sub 2} and YNi{sub 1.66-1.78}P{sub 2} have been determined by powder X-ray diffraction. • The crystal structure of Y{sub 2}Ni{sub 12}P{sub 7} has been established by single crystal diffraction.
