Abstract: | Triphenyl(6-thiopurinyl)tin has been prepared and its structure reinvestigated by X-ray diffraction. In the structure, a new coordination mode was observed that was different from those reported previously from investigations by infrared and Mössbauer spectroscopy. In the molecule, 6-thiopurine coordinated to tin by the S and N(1) atoms. The discrete molecules were connected to form a zigzag 1D network through intermolecular H?N hydrogen bonds. The tin environment is pentacoordinated with cis-trigonal bipyramidal geometry. |
