Ruthenium Complexes [Ph3PCH2CH=CHCH2PPh3]2+[trans-RuCl4(Dmso)2] 2 - and [Ph3PR]+[trans-RuCl4(Dmso)2]-, R = CH2C6H4CN-4, CH2Ph, CPh3, Ph, CH2OCH3: Synthesis and Structure

[Ph3PCH2CH=CHCH2PPh3](2+)[RuCl4(Dmso)(2)] (2) (-) (I) and [Ph3PR](+)[RuCl4(Dmso)(2)](-), where R= CH2C6H4CN-4 (II), CH2Ph (III), CPh3 (IV), Ph (V), CH2OCH3 (VI) have been synthesized by the reaction between ruthenium(III) chloride hydrate and triphenylorganylphosphonium chlorides in dimethyl sulfoxide (Dmso). According to X-ray diffraction data, the phosphorus atoms in the cations of complexes I-III have a slightly distorted tetrahedral coordination (CPC angles, 105.04(14)A degrees-113.1(2)A degrees); P-C bonds, 1.791(3)-1.829(4) ). The dimethylsulfoxide ligands in octahedral [trans-RuCl4(Dmso-S)(2)](-) anions are coordinated to metal atoms via sulfur atoms (Ru-S, 2.3279(9)-2.3494(7) ; Ru-Cl, 2.3202(10)-2.3598(10) ). The SRuS, cis-ClRuCl, and trans-ClRuCl angles variate within 178.92(4)A degrees-180A degrees, 88.06(4)A degrees-92.81(4)A degrees, and 176.52(4)A degrees-180A degrees, respectively. The crystal structure organization of complexes I-III is formed by hydrogen bonds DeA center dot center dot center dot O-Dmso (2.19-2.66 ), Cl center dot center dot center dot De (2.57-2.93 ), and N center dot center dot center dot De (2.25-2.54 ).
