ABSTRACT:
Polymeric complex compounds of molybdenum, tungsten, manganese, rhenium and of the metals of the sub-groups VIII and I of the Periodic Table of Elements, which complex compounds have a silica-type structure are disclosed. At least one amine ##STR1## is bonded coordinately to the central metal atom. The atomic ratio of metal to nitrogen is from 1:1 to 1:10.sup.6. The required charge compensation is effected by means of an anion. In (1), R.sup.1 and R.sup.2 represent a group ##STR2## and R.sup.4 is an alkylene grouping. The oxygen atoms are saturated by silicon atoms of further groups (2), if appropriate with incorporation of crosslinking agents. R.sup.3 may have the meaning of R.sup.1 and R.sup.2, or represents hydrogen, an alkyl group, a cycloalkyl group or the benzyl group. The polymers can contain several metals. The invention also relates to processes for their preparation, and uses in catalysis.
