for ThRu 2 P 2 [URu 2 P 2 ] and Z = 4. The crystal structure was determined from single-crystal X-ray data; R = 0.049 (352 structure factors, 26 variable parameters), R = 0.016 (1109 F values, 27 variables) for the thorium and uranium compound respectively. One phosphorus position of URu 2 P 2-χ was found not to be fully occupied: χ = 0.106(5). The structures of ThRu 2 P 2 and URu 2 P 2 are discussed
摘要 通过将钍粉末与RuP 和铀-钌合金与磷元素在锡助熔剂中反应制备新化合物ThRu 2 P 2 和URu 2 P 2 。化合物在正交空间群 Pnma 中结晶,晶格常数 a = 753.15(5) pm [737.9(2) pm], b = 413.95(4) pm [406.7(1) pm], c = 1047.8(1) pm [1029.4(4) pm] 对于 ThRu 2 P 2 [URu 2 P 2 ] 和 Z = 4。晶体结构由单晶 X 射线数据确定;钍和铀化合物的 R = 0.049(352 个结构因子,26 个可变参数),R = 0.016(1109 个 F 值,27 个变量)。发现URu 2 P 2-χ 的一个磷位置未被完全占据:χ = 0.106(5)。ThRu 2 P 2 和URu 2 P 2 的结构与其他几种相关成分一起讨论,例如BaZn 2 As 2 和BaCu 2
