Organometallic compounds of tetravalent tin,ooks , review articles and periodic surveys covering this field. Invaluable databases relating to studies of organotin compounds by NMR and Mössbauer spectroscopies and single crystal X-ray diffraction also provide an entry into both structural and synthetic aspects of organotin chemistry.
