Single crystals of the title salt, (C(3)H(10)N(3))(2)Sn(CH(3))(2)(H(2)O)(4)(2), formed concomitantly with the already known Sn(CH(3))(3)SO(4)·2H(2)O. In the title structure, the Sn(IV) atom displays a slightly distorted octa-hedral coordination geometry defined by four O water atoms in the equatorial positions and two methyl groups in the axial positions. In the crystal, various O-H⋯O and N-H⋯O hydrogen-bonding inter-actions between the organic cation and the coordinated water mol-ecules as donors and the sulfate O atoms as acceptors result in a three-dimensional structure. The Sn(IV) atom is located on an inversion centre, resulting in half of the complex metal cation being in the asymmetric unit.
标题盐（C₃H₁₀N₃）₂Sn(CH₃)₂(H₂O)₄₂的单晶与已知的[Sn(CH₃)₃]₂SO₄·2H₂O同时形成。在标题结构中，Sn(IV)原子呈现出略微扭曲的八面体配位几何构型，由赤道位置的四个O水原子和轴向位置的两个甲基定义。在晶体中，有机阳离子与作为供体的配位水分子以及作为受体的硫酸根O原子之间存在各种O-H⋯O和N-H⋯O氢键相互作用，从而形成三维结构。Sn(IV)原子位于一个对称中心上，导致一半的复合金属阳离子处于不对称单元中。
