The title salt, [Ag(C5H8N2O2)2]PF6, was obtained by deprotonation and metalation of 1,3-di-meth-oxy-imidazolium hexa-fluorido-phosphate using silver(I) oxide in methanol. The C-Ag-C angle in the cation is 178.1 (2)°, and the N-C-N angles are 101.1 (4) and 100.5 (4)°. The meth-oxy groups adopt an anti conformation. In the crystal, anions (A) are sandwiched between cations (C) in a layered arrangement {C…A…C} n stacked along [001]. Within a C…A…C layer, the hexafluoridophosphate anions accept several C-H⋯F hydrogen bonds from the cationic complex.
标题盐[Ag(C₅H₈N₂O₂)₂]PF₆是通过在甲醇中使用氧化银(I)对1,3 - 二甲氧基咪唑鎓六氟磷酸盐进行去质子化和金属化反应得到的。阳离子中的C - Ag - C角为178.1 (2)°，N - C - N角分别为101.1 (4)°和100.5 (4)°。甲氧基采取反式构象。在晶体中，阴离子(A)以层状排列夹在阳离子(C)之间，沿[001]方向堆叠形成{C…A…C}n结构。在一个C…A…C层内，六氟磷酸根阴离子接受来自阳离子配合物的几个C - H⋯F氢键。
