The reaction of dichloroethylphenyltin(IV), Ph(Et)SnCl2, with phenanthroline monohydrate (phen·H2O) in chloroform, in 1:1 mole ratio, afforded [Ph(Et)SnCl2(phen)]. The crystal structures of dichloroethylphenyltin(IV) and its phenanthroline adduct were studied by X-ray diffraction. In Ph(Et)SnCl2 the tin atom is in a distorted tetrahedral environment, the distortion probably being imposed by weak intermolecular Sn· · ·Cl interactions. In [Ph(Et)SnCl2(phen)] the tin atom is in an octahedral trans-C2, cis-Cl2, N2 environment and weak intermolecular C–H· · ·Cl interactions connect the molecules throughout the lattice. Spectroscopic studies in solution (1H, 13C and 119Sn NMR) were also carried out; the 1H and 13C NMR data in dimethylsulfoxide suggest that [Ph(Et)SnCl2(phen)] remains at least partially undissociated in this solvent.
