| Abstract: | The title compound （I）, C52H50C12O4Sn4, was obtained as an unexpectedly product, and its crystal structure was determined by X-ray diffraction. The analysis of crystal structure indicated that the title compound exhibits the planar, centro-symmetric ladder structure with a fused Sn4O4 ring system. It crystallizes in the monoclinic and space group P21/n. All the Sn atoms are five-coordinated, possessing rather distorted trigonal bipyramidal coordination geometry. The molecules are holding together by the weak C-H……π interaction and Vander Waals forces in the packing structure. |
