The reaction of equimolar amounts of triphenylamyl- and triphenylpropylphosphonium iodides and triethanolammonium iodide with antimony iodide in dimethyl sulfoxide, dioxane, or acetone gave complexes [Ph3AmP] 2 + [Sb2I8 · 2DMSO]2?, [Ph3PrP] 2 + [Sb2I8 · C4H8O2]2?, and [(HOCH2CH2)3NH] 4 + [Sb4I16]4?, the structure of which was established by X-ray diffraction analysis. The cations of all complexes have slightly distorted tetrahedral structure, and the antimony atoms in the anions are hexacoordinated. The crystals of the complexes have intra- and intermolecular contacts, which form the structure. 相似文献

The platinum molecular complex cis-Cl2(Ph3Sb)(Me2S=O)Pt (I) was synthesized by the reaction of tetraphenylstibonium chloride with potassium tetrachloroplatinate in dimethyl sulfoxide. The crystal structure of square-planar complex I was determined by X-ray crystallography. The complex contains, in addition to chlorine atoms, triphenylstibine and DMSO molecules coordinated to the central atom. The bond lengths Pt-Cl, Pt-S, and Pt-Sb are 2.308(1), 2.350(1), 2.195(1), and 2.5118(4) Å, respectively. The compound is the first example of mixed-ligand platinum(II) complex in which the coordination sphere of the central atom contains, along with dimethyl sulfoxide ligand, a tertiary stibine ligand. 相似文献

The ionic complex, methyltriphenylphosphonium(I) trans-bis(dimethylsulfoxido)tetrabromorhodiate, was prepared by the reaction of sodium hexabromorhodiate with methyltriphenylphosphonium bromide in dimethyl sulfoxide and studied by X-ray diffraction. The phosphorus atom in the [Ph3MeP]+ cation has an almost undistorted tetragonal coordination (the CPC angles are 108.3(2)°–110.5(2)°, the P-C bonds are 1.779(6)–1.798(4) Å). In the octahedral complex anion [RhBr4(DMSO)2-trans]?, the dimethyl sulfoxide ligands are coordinated by the sulfur atoms (Rh-S, 2.344(1), 2.336(1); Rh-Br, 2.4839(7)–2.4934(7) Å; SRhS, 179.56(7)°; trans-BrRhBr, 179.30(3)°, 179.56(7)°) (CIF file CCDC no. 978748). 相似文献

Platinum complexes [Ph3PhCH2P]+[(Me2S=O)PtCl3]? I and cis-Cl2(Ph3Sb)(Me2S=O)Pt II were synthesized by reaction of triphenylbenzylphosphonium and tetraphenylstibonium chlorides with potassium tetrachloroplatinate in DMSO. Crystal I is formed by triphenylbenzylphosphonium tetrahedral cations [P-CPh 1.791(4)-1.795(4) Å, P-CAlk 1.811(4) Å; CPC 107.57(18)°-111.46(17)°] and by square anions [(Me2S=O)PtCl3]?

Complexes [(4-MeC6H4)4Sb] 2 + [Hg2I6]2? (I), [(4-MeC6H4)4Sb] 2 + [HgI4]2? (II), [(4-MeC6H4)4Sb] 3 + [Sb3I12]2? (III), were synthesized by reactions of tetra-p-tolylantimony iodide with mercury iodide and antimony iodide, respectively. Tetra-p-tolylantimony perrhenate [(4-MeC6H4)4Sb]+[ReO4]? (IV) was prepared from tetra-p-tolylantimony chloride and sodium perrhenate in acetone. Crystal structures of complexes I, II, and IV were determined by X-ray crystallography. Mercury and rhenium atoms have tetrahedral coordinations in these complexes. The Hg-I and Re-O distances in the structures of I, II, and IV vary within 2.7719(13)–2.7908(12)Å, 2.7028(3)–2.9163(3) Å, and 1.693(3)–1.744(3) Å, respectively. Antimony atoms in two crystallographically independent trinuclear centrosymmetric [Sb3I12]2? anions of complex III have an octahedral environment. Each terminal SbI3 fragment (Sb-It, 2.8265(9)–2.8333(10)Å) is bound to the central atom through tree bridging iodine atoms (Sb(2)-Ibr, 3.2275(9)–3.3620(10)Å). The distances between the central Sb atom and bridging iodine atoms are much shorter (Sb(1)-Ibr, 3.0153(6)–3.0316(6) Å; Sb(3)-Ibr, 2.9926(6)–3.0074(6) Å). 相似文献
