Crystal and molecular structure of phenanthrolinetintetrachloride benzene solvate (4/1)

Abstract

Abstract The crystal structure of [SnCl4(phenanthroline)] · 0.25 C6H6, C13.5H9.5Cl4N2Sn, has been determined at room temperature. The colorless crystals are triclinic, space group P[unk] with unit cell dimensions a = 13.162(7) Å, b = 16.719(3) Å, c = 7.818(5) Å, α = 93.50(3)°, β = 101.89(4)°, γ = 89.76(3)°, Z = 4 and D x = 1.819 Mg m−3. The structure was solved by direct methods and refined by a full-matrix least-squares procedure to final R = 0.053 using 3691 reflections. The unit cell is comprised of four formula units of [SnCl4(phenanthroline)] and one solvent benzene molecule. The tin atom in each molecule exists in a distorted octahedral geometry. The coordinating ability of the phenanthroline ligand is shown to be the same as for the 2,2′-bipyridyl ligand in the solid state.
