Abstract

Взаимодействием хлоридов тетрафенилфосфония и тетрафенилстибония в диме- тилсульфоксиде синтезированы и структурно охарактеризованы комплек- сы[Ph4P][trans-RuCl4(dmso-S)2] (1) и [Ph4Sb(dmso-O)][trans-RuCl4(dmso-S)2] (2). По данным РСА, атомы фосфора в катионах1 имеют мало искаженную тетраэдрическую координацию (Р–С 1,756(16)–1,794(19) Å, СРС 105,4(7)°–111,8(5)°), атомы сурьмы в катионах 2 – искаженную тригонально-бипирамидальную с атомом кислорода диметилсульфоксида в аксиальном положении (Sb–O2,633(15) Å, Sb–С 2,094(15)–2,146(15) Å, СSbO 178,54(16)°). В октаэдрических анионах [транс-RuCl4(dmso-S)2]–комплексов 1 и 2 диметилсульфоксидные лиганды координируются на атом металла атомом серы (Ru–S2,349(3), Ru–Cl2,353(5), 2,355(3) Å и 2,332(3), 2,344(6), 2,336(4)–2,353(3) Å соответстенно), углы SRuS и транс-ClRuCl составляют 180°. Ruthenium complexes [Ph4P][trans-RuCl4(dmso-S)2] (1) and [Ph4Sb(dmso-O)][trans-RuCl4(dmso-S)2] (2) have been synthesized by interaction of tetraphenylphosphonium and tetraphenylstibonium chlorides in dimethylsulfoxide. Their structures have been characterized. According to the X-ray data, the phosphorus atoms in cation 1 have a slightly distorted tetrahedral coordination (P–C 1.756(16)–1.794(19) Å, CPС 105.4(7)°–111.8(5)°), and the antimony atoms in cation 2 have a distorted trigonal-bipyramidal coordination with the dimethyl sulfoxide oxygen atom in the axial position (Sb–O 2.633(15) Å, Sb–C 2.094(15)–2.146(15) Å, CSbO 178.54(16)°). In the [trans-RuCl4(dmso-S)2]– octahedral anion complexes 1 and 2 dimethylsulfoxide ligands are coordinated to the metal atoms by sulfur atoms (Ru–S 2.349(3), Ru–Cl 2.353(5), 2.355(3) Å and 2.332(3)–2.344(6), 2.336(4)–2.353(3) Å, respectively; angles SRuS and trans-ClRuCl constitute 180Ruthenium complexes [Ph4P][trans-RuCl4(dmso-S)2] (1) and [Ph4Sb(dmso-O)][trans- RuCl4(dmso-S)2] (2) have been synthesized by interaction of tetraphenylphosphonium and tetraphenylstibonium chlorides in dimethylsulfoxide.
