and-diiodostannanes [L(n)]2SnX2 (L is the bidentate lactamomethyl C,O-chelating ligand;n is the size of the lactam ring, 5–7; X=Br or I) were prepared both by the direct method from metallic tin and the correspondingN-(halomethyl)lactams and by the reactions of dichlorides [L(n)]2SnCl2 with lithium halides. According to the data of X-ray diffraction analysis, the tin atom in [L(n)]2SnBr2 (n=5–7) and [L(n)]2SnI2 (n=5
