Ruthenium(II)-catalyzed thioether oxidation. 2. Syntheses and crystal structures of two ruthenium(II) complexes with the new linear tridentate ligand 3-(ethylthio)-1-((3-(ethylthio)propyl)sulfinyl)propane
Syntheses of a new tridentate mixed sulfur-donor ligand, 3-(ethylthio)-1-((3-(ethylthio)propyl)sulfinyl)propane (EESP) (3), and two of its ruthenium(II) complexes, RuX/sub 2/(Me/sub 2/SO)(EtS(CH/sub 2/)/sub 3/SO(CH/sub 2/)/sub 3/SEt) (X = Cl, (4), Br (5)), are described. Single-crystal structure determinations were carried out for 4 and 5. Crystals of 5: monoclinic, space group P2/sub 1/ (No. 4), with a = 8.715 (2) A, b = 13.342 (3) A, c = 9.030 (2) A, ..beta.. = 105.47 (2)/sup 0/, and Z = 2. Crystals of 4: a = 8.718 (2) A, b = 13.182 (3) A, c = 8.912 (2) A, and ..beta.. = 105.87 (2)/sup 0/. The coordination geometry in both 4 and 5 is trans-thioether, cis-halo, and cis-sulfoxide. The tridentate, chelate ligand coordinates meridionally to the Ru(II) ion. In both structures, the two six-atom chelate rings have different conformations: one ring has a distorted chair conformation and the other ring has a twist-boat conformation. The major geometrical details for 5 are Ru-Br(1) = 2.601 (1) A, Ru-Br(2) = 2.578 (1) A, Ru-S(1) = 2.275 (2) A, Ru-S(2) = 2.393 (2) A, Ru-S(3) = 2.235 (2) A, Ru-S(4) = 2.372 (2) A, and Br(1)-Ru-Br(2) = 86.4 (1)/sup 0/. The related details for the chloro complex, 4, are Ru-Cl(1) = 2.467 (1) A, Ru-Cl(2) = 2.444 (1) A, Ru-S(1) = 2.269 (1) A, Ru-S(2) = 2.386 (1) A, Ru-S(3) = 2.218 (1) A, Ru-S(4) = 2.365 (1) A, and Cl(1)-Ru-Cl(2) = 86.4 (1)/sup 0/.
