Unlike diorganotin(IV) dihalides, triphenyl- and tribenzyl-tin chlorides do not react with Schiff-base complexes M(SB) (M = Cu(II), Ni(II) and Zn(II); SB = N,N'-ethylenebis-salicylideneaminato and related salicylaldimine ligands). Triphenyltin chloride does however form 1:1 addition complexes with 3,3'-methoxy substituted salicylaldimines of Ni(II) and Cu(II), but only in the presence of water. Each of these complexes contains the aquo adduct SnPh3Cl.H2O, with the donor water molecule engaged in hydrogen bonding interactions with the four oxygen atoms of the divalent metal salicyaldimine. These structural features were confirmed crystallographically for (SnPh3Cl.H2O)-Ni(3-MeOsal1,3pn) (1:1) [H(2)3-MeOsal1,3pn = N,N'-bis(3-methoxysalicylidene)propane-1,3-diamine]. In the case of [SnPh3Cl.H2O]-[Ni(3-MeOsal1,3pn).H2O] (1:1) both the water molecule coordinated to nickel and the water molecule coordinated to tin engage in hydrogen bonding interactions with the Schiff-base oxygen atoms, thereby creating centrosymmetric hydrogen-bonded dimers.
