ABX-Verbindungen mit Ni2In-Struktur Darstellung und Struktur der Verbindungen CaCuP(As), SrCuP(As), SrAgP(As) und EuCuAs / ABX Compounds with the Structure Ni2In Preparation and Crystal Structure of CaCuP(As), SrCuP(As), SrAgP(As), and EuCuAs

Abstract

The compounds CaCuP(As), SrCuP(As), SrAgP(As) and EuCuAs were prepared and investigated by X-ray methods. They are isotypic and crystallize in a modified Ni2In structure (space group P 63/mmc-D6h 1) with the lattice constants: CaCuP a = 405.5(1) pm, c = 780.3(3) pm, CaCuAs a = 418.4(1) pm, c = 786.8(2) pm, SrCuP a = 414.6(1) pm, c = 837.6(3) pm, SrCuAs a = 427.3(2) pm, c = 845.2(3) pm, EuCuAs a = 425.4(2) pm, c = 827.4(3) pm, SrAgP a = 440.9(1) pm, c = 823.0(3) pm, SrAgAs a = 452.9(1) pm, c = 829.1(2) pm.
