Characterization and X-Ray Structure of the Adduct Formed Between Triphenyltin Chloride and Dicyclohexylphosphinyl-N-methyl(thioformamide): Ph₃Sn[Cy₂P(O)C(S)N(H)Me]Cl

Abstract

The reaction of Ph₃SnCl and Cy₂P(O)C(S)N(H)Me yields the air-stable adduct Ph₃Sn[Cy₂P(O)-C(S)N(H)Me]Cl which features a trigonal bipyramidal tin atom geometry with a chlorine atom [Sn-Cl 2.4236(9)Ǻ] and an oxygen atom [Sn-O 2.523(2)Ǻ], derived from a monodentate phosphinyl(thioformamide) ligand, occupying the axial positions. The pale-yellow crystals are monoclinic, space group P2₁/c with unit cell dimensions a 10.050(1), b 16.501(1), c 19.273(1) Ǻ, β 102.12(1)°, Z 4; the structure was refined to final R 0.031 by using 5384 reflections.
