The invention relates to cyclic aza-sila compounds that are made of 4 to 10 units of the general formulas (I) and (II) bonded by means of Si—Si or Si—N single bonds, wherein Y is selected from among —NR
1
R
2
, hydrogen, and a halogen, R
1
and R
2
are selected from among hydrogen and a hydrocarbon group having 1 to 20 carbon atoms, and R
3
is a hydrocarbon group having 1 to 20 carbon atoms, with the stipulation that at least two units of the general formula (I) are bonded to each other in the ring by means of an Si—Si single bond, that at most 35 mol % of the groups Y is a hydrogen, and that at most 15 mol % of the groups Y is a halogen, and to a method for the production thereof.
