Abstract
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 6 . The required charge compensation is effected by means of an anion. In (1), R 1 and R 2 represent a group ##STR2## and R 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 3 may have the meaning of R 1 and R 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.
