Synthesis and crystal structure of N,N '-bis(2-aminoethyl)-2,4-pentanediiminatogold(III) perchlorate

A synthetic procedure is described for N,N ' -bis(2-aminoethyl)-2,4-pentane diiminatogold(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 = 22.98 5(5) Angstrom, beta = 90.35(3)degrees V = 1664.2(5) Angstrom (3), space gro up P2(1)/n, Z = 4, d(calc) = 2.324 g/cm(3). The structure consists of nearl y planar acyclic cations [C9H19AuN4](2+) and perchlorate anions [ClO4](-). The C-C and C-N bonds inside the beta -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; solubil ity in water is 0.8%.
