Synthesis and Crystal Structure of a Triphenyltin Derivative of 4,5-Diphenyl-4-oxazoline-2-thione

抄録

The title complex, [Sn(C₆H₅)₃(C₁₅H₁₀NOS)], was synthesized by a reaction of the heterocyclic ligand and triphenyltin chloride in benzene. The crystal structure was determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P2₁/n with a = 9.748(2)Å, b = 18.857(4)Å, c = 15.295(3)Å, β = 101.175(3)Å, Z = 4, V = 2758.1(1)ų. Its crystal structure was determined and refined to a final R = 0.0751 for 13949 independent reflections. The center Sn atom is four-coordinated, so that the C₃S donor set defines a distorted tetrahedral geometry.
