[Sn(C(6)H(5))(3)(C(7)H(6)NO(2)S)], (I), and (4-nitrophenylsulfonylmethyl)triphenylstannane, [Sn(C(6)H(5))(3)(C(7)H(6)NO(4)S)], (II), the molecules are linked by paired C[bond]H...O hydrogen bonds into centrosymmetric dimers which combine to form sheets. In (I), two such dimers form to give R(2)(2)(10) and R(2)(2)(24) rings. In (II), similar dimers form, here with R(2)(2)(10) and R(2)(2)(18) rings, but
在(4-硝基苯基硫烷基甲基)三苯基锡的晶体结构中,[Sn(C(6)H(5))(3)(C(7)H(6)NO(2)S)],(I)和( 4-硝基苯基磺酰基甲基)三苯基锡烷,[Sn(C(6)H(5))(3)(C(7)H(6)NO(4)S)],(II),这些分子通过成对的C [键] H ... O氢键形成向心对称的二聚体,它们结合在一起形成片状。在(I)中,两个这样的二聚体形成给出R(2)(2)(10)和R(2)(2)(24)环。在(II)中,形成类似的二聚体,此处带有R(2)(2)(10)和R(2)(2)(18)环,但由于存在砜基而具有一个额外的二聚体,从而得到(2)(2)(10)响起。在两种结构中,C H ... pi相互作用导致片材的宽度加倍。
