| abstract | process for the production of preparations containing water from metal complexes of the platinum group (mgp), use of preparations containing water, process for the production of electroplating baths and preparation containing water from a pt (ii) complex the invention relates to a method for the production of aqueous preparations of platinum group metal complexes (mgp) pt, pd, rh e ir of general formula [ma / mb / mc (l) a (h2o) b (o2-) c ( oh-) d] (oh-) e (h +) f, where ma = ptii or pdii, mb = ptiv, mc = rh or ir, l is a monodentate or bidentate neutral donor ligand and a is an integer between 1 and 4 (or 2) and / or between 1 and 6 (or 3), b is an integer between 0 and 3 (or 5), c is an integer between 0 and 3 (or 4), d is an integer between 0 and 3 (or 5), and is an integer between 0 and 2 (or 3 or 4) and f is an integer between 0 and 4 (or 5). in the method according to the invention, the hydroxylated complexes h2pd (oh) 4 (in the case of ma = pdii), h2pt (oh) 6 (in the case of ma = ptii and mb = ptiv) or h3mc (oh) 6 (for mc = rhiii iriii) are converted, in the presence of donor ligands, in which at least one hydroxyl group of the hydroxylated complex is replaced. preferably, the reaction takes place at temperatures in the range of 40 to 110 ° C, with a reaction time between 2 and 24 hours, where, where ma = ptii, the conversion takes place, additionally, in the presence of a reducing agent. the method further comprises, optionally, an exchange of oh anions attached outside the sphere of the complex, for other anions (for example, hydrogen carbonate or carbonate anions). aqueous preparations contain mgp complexes, such as [pt (en) 2] (oh) 2, [pt (ea) 4] (oh) 2 or [rh (nh3) 6] (oh) 3 and are used to produce electroplating baths, heterogeneous catalysts or metallic powders, for example. |
