The structure of the title compound, (C(12)H(24)N)(2)[Sn(2)(C(6)H(5))(4)(C(2)O(4))(3)(H(2)O)(2)], consists of a bischelating oxalate ion, located on an inversion center, which is linked to two SnPh(2) groups. The coordination sphere of the Sn(IV) ion is completed by a monochelating oxalate anion and a water mol-ecule. The Sn(IV) atoms are thus seven-coordinated. The discrete binuclear units are further connected by hydrogen bonds, leading to a supra-molecular crystal structure. The asymmetric unit contains one half dianion and one (Cy(2)NH(2))(+) cation.
标题化合物(C₁₂H₂₄N)₂[Sn₂(C₆H₅)₄(C₂O₄)₃(H₂O)₂]的结构由位于对称中心的双螯合草酸根离子组成,该离子与两个SnPh₂基团相连。Sn(IV)离子的配位球由一个单螯合草酸根阴离子和一个水分子完成。因此,Sn(IV)原子为七配位。离散的双核单元通过氢键进一步连接,形成超分子晶体结构。不对称单元包含半个二价阴离子和一个(Cy₂NH₂)⁺阳离子。
