Abstract: Formed spherical polymeric complexes of metals of the 8th subgroup of the periodic system with ligands of an organosiloxane copolycondensate, optionally cross-linked by means of cross-linking agents containing Si, Ti, Zr and/or Al (statistical, block-shaped or mixed). This copolycondensate consists of the units (see fig. I) (see fig. II) and wherein (see fig. III) , wherein R5 stands for alkylines with C1 - C10 linked directly to P or N, respectively, cycloalkyls with C5 - C8 or (see fig. IV) respectively (see fig. V) The ratio between the molar number of units (II) and the molar number of the bonded metal atoms amounts to 1:1 to 1000:1, and the ratio between the units (I) and (II) preferably is 10:90 to 95:5 mole %. The polymeric complex compounds are present macroscopically as spherical particles with diameters of 0.01 to 3.0 mm, with a BET-surface of >0 to 1000 m2/g, a specific pore volume of 0.01 to 6.5 ml/g, and a bulk density of 50 to 1000 g/l. Several processes for preparing the substances are provided, with special secondary treatment stages, and use of the polymeric metal complexes as catalysts in organic chemistry are described.
