Abstract

The organotin(IV) chlorides RnSnCl4−n (n = 3, R = Ph, PhCH2, n−Bu; and n =2, R = n−Bu, Ph, PhCH2) react with 4,4′‐bipyridine (4′4‐bpy) to give ((Ph3SnCl)2(4,4′‐bpy)1.5(C6H6)0.5) (1), ((PhCH2)3‐ SnCl)2 (4,4′‐bpy) (2), ((n−Bu)3SnCl)2(4,4′‐bpy) (3), ((n−Bu)2SnCl2(4,4′‐bpy)) (4), (Ph2SnCl2(4,4′‐bpy)) (5), and ((PhCH2)2SnCl2(4,4′‐bpy)) (6). The new complexes have been characterized by elemental analyses, IR, 1H, 13C, 119Sn NMR spectroscopy. The structures of (1), (2), (4), and (6) have been determined by X‐ray crystallography. Crystal structures of (1) and (2) show that the coordination number of tin is five. In complex (1), two different molecules exist: one is a binuclear molecule bridged by 4,4′‐bpy and another is a mononuclear one, only one N of 4,4′‐bpy coordinate to tin. Complex (2) contains an infinite 1‐D polymeric binuclear chain by weak Sn…Cl intermolecular interactions with neighboring molecules. In the complexes (4) and (6), the tin is six‐coordinate, and the 4,4′‐bpy moieties bridge adjacent dialkyltin(IV)dichloride molecules to form a linear chain. © 2004 Wiley Periodicals, Inc.
