摘要：

The new ternary phosphides SrNi9P5 and BaNi10P6 were synthesized by heating the elements at 900-degrees-1100-degrees-C. Single crystal X-ray methods revealed that SrNi9P5 is isotypic with BaNi9P5 and crystallizes hexagonally [P6(3)/mmc; Z = 2; a = 6.529(1) angstrom, c = 10.732(1) angstrom], whereas BaNi10P6 forms a new structure with orthorhombic symmetry [Cmca; Z = 4; a = 6.449(1) angstrom, b = 16.191 (1) angstrom, c = 8.784(1) angstrom]. The structures are best described as an arrangement of alkaline-earth metal atoms, which are surrounded by Ni18P12(SrNi9P5) and Ni14P12 cages (BaNi10P6), respectively.
