Abstract: | Preparation and Crystal Structure of A Ni10P3 ( A : Zn, Ga, Sn, Sb) Four compounds ANi10P3 (A: Zn, Ga, Sn, Sb) were prepared by heating mixtures of the elements and investigated by means of X‐ray methods. Single crystal structure determinations of ZnNi10P3 (a = 7.665(1), c = 9.360(1) Å) and SnNi10P3 (a = 7.674(1), c = 9.621(1) Å) respectively showed, that they are isotypic and crystallize in a new structure (P3m1; Z = 3). This type is characterized by 320 and 324 cages of Ni atoms (Frank Kasper polyhedra), which are connected with each other. A atoms are located in the centres of these polyhedra and have no direct bonds to the P atoms. |
