The reaction of 6-methylpyridine-2-carboxaldehyde phenylhydrazone (L) with Ph2SnCl2 has resulted in the formation of a complex salt [LH+]2[Ph2SnCl4]2-. X-ray diffraction studies on the salt reveal the structure of the [Ph2SnCl4] dianion to be centrosymmetric with the tin atom in a distorted octahedral trans-C2Cl4 environment; Sn-Cl(1) 2.598(2), Sn-Cl(2) 2.5875(7) and Sn-C(1) 2.146(3) A. Associated with the dianion are two [PhN(H)NC(H)C5H3(Me)N(H)] cations via two hydrogen bonding contacts apiece, unusually involving a true Sn-Cl bond.
