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 crystal lizes in a space group (C2/c) which differs from those usually found f or triaryltin halides. The structure comprises molecules forming ladde rs using overlapping aryl or tert-butyl groups. This relatively open b ut organized arrangement contrasts with the more closely packed but ra ndom one found for Ph3SnCl and may account for the differences in phys ical properties of these two triaryltin chlorides.
