Structure of Minor Products of Potassium Diiododicyanoaurate Reactions with Tetraorganylphosphonium and -Stibonium Halides

Abstract

The structure of four complexes, minor products of potassium diiododicyanoaurate reactions with tetraorganylphosphonium and -stibonium halides [Ph₃PEt]₂[Au(CN)₂I₂][I₃] (1), [Ph₃PCH₂СN]₂[Au(CN)₂I₂][I₃] (2), [p-Tol₄Sb]₂[Au(CN)₂I₂][I₃] (3), and [Ph₄Sb]₂[Au(CN)₂I₂][I₃]×2I₂ (4) in acetonitrile or water, was determined by X-ray structural analysis, performed on an automatic four-circle diffractometer D8 Quest Bruker (МоК_α, λ = 0.71073 Å, 293 К. 1 (C₄₂H₄₀AuI₅N₂P₂, P-1, a = 7.865(4), b = 9.933(4), c = 16.437(6) Å, a = 97.204(14), β = 98.789(19), g = 110.82(2) deg., V = 1163.5(8) ų, Z = 1, R₁ = 0,0467, wR₂ = 0,1173. 2 (C₄₂H₃₄AuI₅N₄P₂, P-1, a = 8.490(4),
