title: {4-[(7-Chloro-4-quinol-yl)amino]-N,N-di-ethyl-penta-naminium}(triphenyl-phos-phine)gold(I) dinitrate.
abstract: The title compound, [Au(C(18)H(27)ClN(3))(C(18)H(15)P)](NO(3))(2), is a coordination complex of gold(I) triphenyl-phosphine with the N atom in the quinoline ring of the common anti-malarial compound chloro-quine (CQ). The pendant diethyl-amino group of the CQ ligand was found to be protonated. The complex exhibits a nearly linear coordination geometry around the Au(I) atom [N-Au-P = 176.94 (6)°], with Au-N and Au-P bond lengths of 2.070 (2) and 2.2338 (7) Å, respectively. The diethylammonium group and one of the two nitrate counter-ions are disordered with occupancy ratios of 0.519 (4):0.481 (4). The nitrate anions are hydrogen bound to both the amino and ammonium groups of the N,N-diethylpentanaminium fragment of the CQ.
