摘要：

Several new ternary phosphides and arsenides of nickel were prepared by reaction of the elements. SrNi5P3, SrNi5AS3, and EuNi5AS3 crystallize in the LaCo5P3 structure with the following lattice constants [A]: [GRAPHICS] BaNi9P5 (a = 6.534(1) angstrom, c = 10.847(2) angstrom) and BaNi9AS5 (a = 6.760(1) angstrom, c = 11.226(2) angstrom) crystallize in a new type of structure (P6(3)/mmc, Z = 2). The characteristic polyhedra are trigonal Ni-antiprisms centered by P or As atoms and trigonal Ni-prisms with vacant centres and sides capped by non-metal atoms. U2Ni12P7 (a = 9.077(2) angstrom, c = 3.694(1) angstrom) has a Zr2Fe12P7 structure (P6BAR, Z = 1).
