Abstract
A synthetic procedure is described for N,N'-bis(2-aminoethyl)-2,4-pentanediiminatogold(III) perchlorate. The complex was investigated by X-ray phase and X-ray diffraction analyses, electron spectroscopy, and IR spectroscopy. Crystal data for C9H19AuN4Cl2O8: a = 10.093(2), b = 7.1740(10), c = 22.985(5) A, β = 90.35(3)°, V = 1664.2(5) A3, space group P2(1)/n, Z = 4, dcalc = 2.324 g/cm3. The structure consists of nearly planar acyclic cations [C9H19AuN4]2+ and perchlorate anions [ClO4]–. The C–C and C–N bonds inside the β-diiminate ring are delocalized. The parameters of the [C9H19AuN4]2+ cation are compared with those in related complexes. The compound is stable in air for at least half a year; solubility in water is 0.8%.
