摘要:
The invention describes a process for producing metal complexes of the general formula (2): [MaLxXn]Ym (2), where M is a metal from the group comprising Mn(II), Mn(III), Mn(IV), Fe(II), Fe(III) or Fe(IV), X is a coordinated compound selected from mono- bi- or tri-charged anions or neutral molecules which are able to coordinate with a metal mono- bi- or tri-dentate, Y represents a non-coordinated counter-ion which ensures charge equalization of the complex, L represents a ligand of the general formula (1) or the protonized or de-protonized form thereof, and a, x, n, m, R, R1, R2, R3 and z have the meaning specified in claim 1. Said process is characterized in that the reaction of a ligand of the formula (1) with an iron or manganese salt in a heterogeneous reaction is carried out in water, where the reaction is carried out in a temperature range of 35 to 50° C. and the pH value of the reaction mixture is from 1 to 3 after the addition of the iron or manganese salt.

An injection valve of an internal combustion engine comprises a valve portion arranged in a bore of the valve housing, forming a high-pressure side annular chamber sealed in relation to the valve housing by the sealing contact of the valve portion with a shoulder of the bore and at an axial distance therefrom, by a sealing ring. A spacing sleeve is arranged in the annular chamber and keeps the sealing ring at a minimum axial distance from the shoulder of the bore.
