TRIS(4-TERT-BUTYLPHENYL)CHLOROTIN(IV)

The structure of tris(4-tert-butylphenyl)chlorotin(IV), [Sn(C10H13)3Cl], has been determined by single-crystal X-ray diffraction. It crystallizes in a space group (C2/c) which differs from those usually found for triaryltin halides. The structure comprises molecules forming ladders using overlapping aryl or tert-butyl groups. This relatively open but organized arrangement contrasts with the more closely packed but random one found for Ph3SnCl and may account for the differences in physical properties of these two triaryltin chlorides.
