In the crystal structures of (4-nitrophenylsulfanylmethyl)triphenylstannane, [Sn(C₆H₅)₃(C₇H₆ NO₂S)]. (I), and (4-nitrophenylsulfonylmethyl)triphenylstannane. [Sn(C₆H₅)₃(C₇H₆ NO₄S)], (II), the molecules are linked by paired C-H...O hydrogen bonds into centrosymmetric dimers which combine to form sheets. In (I), two such dimers form to give R₂²(10) and R₂²(24) rings. In (II), similar dimers form, here with R₂²(10) and R₂²(18) rings, but with an additional dimer due to the presence of the sulfone group, giving R₂²(10) rings. In both structures, C-H...π interactions lead to a doubling of the width of the sheets.
