A size-controlled synthesis of gold nanoparticles has been developed by the thermolysis of AuCl(SMe 2 ) in the presence of alkylamines at 120 • C. In the procedure, the key intermediate was [Au(NH 2 R) 2 ]Cl, detected by electrospray ionization (ESI) mass spectrometry. This thermally unstable intermediate was reduced by alkylamines under mild conditions to produce alkylamine-capped gold nanoparticles. The average diameters of the gold nanoparticles could be regulated in a range from 4.3 to 6.1 nm by applying primary alkylamines with alkyl chains of different lengths. Larger gold nanoparticles with diameters from 10 to 22 nm were prepared by a combination of alkylamines and alkylcarboxylic acids with various lengths of the alkyl chains. The gold nanoparticles were characterized by transmission electron microscopy (TEM), UV/Vis absorption spectroscopy, powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), gas chromatography/mass spectroscopy (GC/MS), and thermogravimetric and differencial thermal analyses (TG/DTA).

The single crystal X-ray structure determinations are reported for [Ph 4 As][Au(N 3 ) 4 ] (1) and Ph 3 PAuN 3 (2). Compound 1 is an ionic species with a ªwindmillº shaped anion. It crystallizes in the monoclinic space group C2/c, a = 18.396(2), b = 6.2492(4), c = 23.555(2) A Ê ; b = 107.98(1)°, Z = 4, R1 (all data) = 0.0227, wR2 = 0.0374. The lattice parameters of compound 2, which crystallizes in the orthorhombic space group P2 1 2 1 2 1 , are a = 10.9252(1), b = 11.5642(1), c = 13.0993(1) A Ê ; Z = 4, R1 (all data) = 0.0176, wR = 0.0334.The experimentally obtained X-ray data and vibrational frequencies of both compounds were compared with those calculated at B3LYP/LANL2DZ and B3LYP/SDD level of theory and for 1 also at the MP2/SDD level.

The coordination geometry at gold is linear, with Au-P 2.278 (2), Au-C 2.003 (7)A, P--Au-C 177.0 (2) °.Considerable distortions of the structure (involving the light atoms) were observed until systematic errors (extinction, absolute structure) were minimized.
