| Section2 = | Section3 = }} Dichlorotris(triphenylphosphine)ruthenium(II) is a coordination complex of ruthenium. It is a chocolate brown solid that is soluble in organic solvents such as benzene. The compound is used as a precursor to other complexes including those used in homogeneous catalysis. ==Synthesis and basic properties== RuCl2(PPh3)3 is the product of the reaction of ruthenium trichloride trihydrate with a methanolic solution of triphenylphosphine.〔Stephenson, T. A.; Wilkinson, G. "New Complexes of Ruthenium (II) and (III) with Triphenylphosphine, Triphenylarsine, Trichlorostannate, Pyridine, and other Ligands", ''J. Inorg. Nucl. Chem.'', 1966, ''28'', 945-956. 〕〔P. S. Hallman, T. A. Stephenson, G. Wilkinson "Tetrakis(Triphenylphosphine)Dichloro-Ruthenium(II) and Tris(Triphenylphosphine)-Dichlororuthenium(II)" ''Inorganic Syntheses'', 1970 Volume 12, . 〕 :2 RuCl3(H2O)3 + 7 PPh3 → 2 RuCl2(PPh3)3 + 2 HCl + 5 H2O + 1 OPPh3 The coordination sphere of RuCl2(PPh3)3 can be viewed as either five-coordinate or octahedral. One coordination site is occupied by one of the hydrogen atoms of a phenyl group.〔Sabo-Etienne, S.; Gellier, M., "Ruthenium: Inorganic and Coordination Chemistry", ''Encyclopedia of Inorganic Chemistry'', 2006, John Wiley & Sons. 〕 This Ru---H agostic interaction is long (2.59 Å) and weak. The low symmetry of the compound is reflected by the differing lengths of the Ru-P bonds: 2.374, 2.412, and 2.230 Å.〔La Placa, S. J.; Ibers, J.A., "A Five-Coordinated d6 Complex: Structure of Dichlorotris(triphenylphosphine)ruthenium(II)", ''Inorganic Chemistry'', 1965, 4, 778-78. 〕 The Ru-Cl bond lengths are both 2.387 Å. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dichlorotris(triphenylphosphine)ruthenium(II)」の詳細全文を読む スポンサード リンク
