Structure of minor products of potassium diiododicyanoaurate reactions with tetraorganylphosphonium and -stibonium halides

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 (Мо Кα , 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) Å3, Z = 1, R 1 = 0,0467, wR 2 = 0,1173. 2 (C42H34AuI5N4P2, P -1, a = 8.490(4), b = 11.563(4), c = 13.625(6) Å, a = 66.287(19), β = 74.57(2), g = 76.283(19) deg., V = 1167.6(9) Å3, Z = 1, R 1 = 0.0848, wR 2 = 0.2079. 3 (C58H56AuI5N2Sb2, P -1, a = 9.984(4), b = 10.073(4), c = 15.749(9) Å, a = 93.581(18), β = 101.91(2), g = 95.342(15) deg., V = 1537.5(12) Å3, Z = 1, R 1 = 0.0612, wR 2 = 0.1704. 4 (C50H41AuI8N2Sb2, P -1, a = 10.057(8), b = 14.131(10), c = 21.243(12) Å, a = 81.28(2), β = 85.68(3), g = 81.17(4) deg., V = 2944(3) Å3, Z = 2, R 1 = 0.0488, wR 2 = 0.1080.
