Reactions of 2-bromopyridine and 2-bromo-6-methylpyridine with n-BuLi and tin tetrachloride afforded Sn(2-py)4 (1a) and Sn(6-Me-2-py)4 (1b), respectively. The identities of the two compounds were unambiguously proved by microanalyses, NMR (1H, 13C, 119Sn) spetroscopy, and single-crystal X-ray diffraction studies.
