The First Iridiumphosphates Two polymorphs of iridium(III)-metaphosphate Ir(PO3)3 and an iridium(IV)-silicophosphate (Ir1−xSix)3[Si2O(PO4)6] (x ∼ 0.5) were synthesized and their crystal structures determined from single-crystal x-ray data. Pale pink needles of triclinic Ir(PO3)3 (Ru(PO3)3 structure type, (No. 2), Z = 2, a = 6.9574(6) A, b = 10.3628(9) A, c = 5.0288(4) A, α = 92.28(1)°, β = 92.80(1)°
第一个磷酸铱 合成了铱 (III)-偏磷酸 Ir(PO3)3 和铱 (IV)-硅磷酸盐 (Ir1−xSix)3[Si2O(PO4)6] (x ∼ 0.5) 的两种多晶型物,并确定了它们的晶体结构来自单晶 X 射线数据。三斜 Ir(PO3)3 (Ru(PO3)3 结构类型,(No. 2), Z = 2, a = 6.9574(6) A, b = 10.3628(9) A, c = 5.0288(4) ) A, α = 92.28(1)°, β = 92.80(1)°, γ = 98.60(1)°, 1574 次独立反射, 122 个参数, R1 = 0.028, wR2 = 0.061) 是从偏磷酸熔体中生长出来的。C型Ir(PO3)3(C-Al(PO3)3结构型,Cc(No. 14),Z = 12,a = 13.103(2) A,b = 19.183(1) A, c = 9.354(1) A
