The compounds RE19(C2)3I34 (RE = Y, Gd) were prepared from RE, REI3 and carbon in a molar ratio of 20:34:18 by the addition of three parts of REN at 920 °C (Y) and 900 °C (Gd), respectively, forming moisture sensitive, black shiny brittle polyhedra. X-ray single crystal investigations indicated the triclinic system and E value statistics showed P, a = 9.3683(9) A, b = 10.3410(9) A, c = 22.1726(20) A
化合物 RE19(C2)3I34 (RE = Y, Gd) 由 RE、REI3 和碳以 20:34:18 的摩尔比通过加入三份 REN 在 920 °C (Y) 和 900 °C 下制备C(Gd)分别形成对湿气敏感、黑色有光泽的脆性多面体。X射线单晶研究表明三斜晶系和E值统计显示P, a = 9.3683(9) A, b = 10.3410(9) A, c = 22.1726(20) A, α = 79.104(10)°, β = 88.175(11)°, γ = 69.227(10)° Y19(C2)3I34 和 a = 9.4172(9) A, b = 10.3390(10) A, c = 22.3711(24) A, α = (19.00) )°, β = 88.320(12)°, γ = 69.250(11)° 对于 Gd19(C2)3I34,分别。RE原子形成以C2基团为中心的两
