this invention relates to formed , polymeric complexes of metals of the eighth 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 , in the form of statistical , block or mixed copolycondensates . the ratio between the number of moles of phosphine units and the number of moles of bound metal atoms is 1 : 1 to 1000 to 1 and the ratio between the amine units and the phosphine is preferably 5 : 95 to 95 : 5 mole %. the polymeric complex compounds are present macroscopically as spherical particles with a diameter in the range of 0 . 01 to 3 . 0 mm , a bet surface of greater than 0 to 1000 m 2 / g , a specific pore volume of 0 . 01 to 6 . 5 ml / g and a bulk density of 50 to 1000 g / l . the invention also includes several methods of preparing the complexes with post - treatment stages and the use of the polymeric metal complexes as catalysts in organic chemistry .
