BaAl 4 -Strukturvarianten bei ARu 2 X 2 (A = Ca, Sr, Ba, Eu; X = P, As) und APt 2 P 2—x (A = Ca, Eu) / BaAl 4 -Denvative Structures of ARu 2 X 2 (A = Ca, Sr, Ba. Eu; X = P, As) and of APt 2 P 2-x (A = Ca, Eu)

Compounds ARu 2 P(As) 2 (A = Ca, Sr. Ba. Eu) were found to have the ThCr 2 Si 2 -type structure (14/mmm). Single crystals of CaRu 2 P 2 (a = 404.6 pm, c = 977.1 pm) and EuRu 2 P 2 (a = 402.9 pm, c = 1077.2 pm) were obtained using tin as a flux. In the case of the Pt compounds, single crystals could...

Summary:Compounds ARu 2 P(As) 2 (A = Ca, Sr. Ba. Eu) were found to have the ThCr 2 Si 2 -type structure (14/mmm). Single crystals of CaRu 2 P 2 (a = 404.6 pm, c = 977.1 pm) and EuRu 2 P 2 (a = 402.9 pm, c = 1077.2 pm) were obtained using tin as a flux. In the case of the Pt compounds, single crystals could be isolated from powder samples. Ca(Eu)Pt 2 P 2-x crystallizes isotypically in a new structure type which can be described as a stacking variation of the CaBe 2 Ge 2 -type structure (14/mmm; CaPt 2 P 1.43 : a = 409.9 pm, c = 1895.1 pm; EuPt 2 P 1 . 62 : a = 414.3 pm; c = 1912.0 pm). The crystal structures of Ca(Eu)Ru 2 P 2 and Ca(Eu)Pt 2 P 2-x were refined from four-circle diffractometer data. Magnetic susceptibility measurements prove the divalent nature of Eu in all Eu compounds.
