In the crystal structure of the title salt, Ag(NH(3))(2)(C(7)H(6)O(7)S(2))(2)·H(2)O, the four independent Ag(I) complex cations all lie on special positions of m site symmetry, as do the two independent 2-hy-droxy-5-methyl-benzene-1,3-disulfonate anions. The Ag(I) cations exist in an almost linear coordination geometry [N-Ag-N = 175.2 (2), 178.08 (16), 175.8 (2) and 178.20 (19)°]. The water mol-ecule is disordered about a mirror plane. Two independent complex cations are linked by an Ag⋯Ag inter-action of 3.3151 (1) Å, furnishing a linear Ag(NH(3))(2) polycationic chain running along b. The free complex cations, polycationic chain and 2-hy-droxy-5-methyl-benzene-1,3-disulfonate anions inter-act via N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional network.
在标题盐[Ag(NH₃)₂]₄(C₇H₆O₇S₂)₂·H₂O的晶体结构中，四个独立的Ag(I)络合阳离子均位于m位点对称的特殊位置，两个独立的2-羟基-5-甲基苯-1,3-二磺酸盐阴离子也是如此。Ag(I)阳离子以近似线性的配位几何构型存在[N-Ag-N = 175.2 (2)、178.08 (16)、175.8 (2)和178.20 (19)°]。水分子围绕一个镜面无序排列。两个独立的络合阳离子通过3.3151 (1) Å的Ag⋯Ag相互作用相连，形成一条沿b轴延伸的线性[Ag(NH₃)₂]ₙ聚阳离子链。游离的络合阳离子、聚阳离子链和2-羟基-5-甲基苯-1,3-二磺酸盐阴离子通过N-H⋯O和O-H⋯O氢键相互作用，形成三维网络。
