Polymeric metal-amine complex compounds, processes for their preparation and use

A polymeric complex organosiloxane amine of a member selected from the group consisting of molybdenum, tungsten, manganese, rhenium and a metal of the sub-groups VIII and I of the Periodic Table, wherein at least one amine of the formula ##STR18## is bonded coordinately to each central metal atom, the metal:nitrogen atomic ratio is from 1:1 to 1:10.sup.6, any coordination points at the metal atom which are still free are occupied by other electron pair donors, and the required charge compensation is effected by means of an inorganic or organic anion, and in the formula (1) R.sup.1 and R.sup.2 represent a group of the formula ##STR19## R.sup.4 denotes a linear or branched alkylene group having 1 to 10 C atoms or a cycloalkylene group having 5 to 8 C atoms, or represents the units:

• ##STR20## wherein n is 1 to 6 methylene groups linked to a nitrogen atoms,
• R.sup.1 and R.sup.2 can be identical or different,
• and the free valences of the oxygen atoms are saturated either by silicon atoms of further groups of the formula (2) and/or by crosslinking bridge members ##STR21## wherein E represents silicon, titanium or zirconium, or by the units:
• ##STR22## wherein R' is a methyl or ethyl group and the ratio of the silicon atoms in (2) to the bridge atoms silicon, titanium, zirconium and aluminum can be from 1:0 to 1:10,
• R.sup.3 has the same meaning as R.sup.1 and R.sup.2, or represents hydrogen, a linear or branched alkyl group having 1 to 10 C atoms or a cycloalkyl group having 5 to 8 C atoms or the benzyl group.
