The invention relates to chromium complexes of the formula ##STR1## in which A is the radical of a dicyclically metallizable azo or azomethine dye, B is the radical of a monoanionic bidentate complexible organic compound which is bonded to the chromium atom via oxygen atoms, L is a colorless monofunctional ligand, X is halogen-substituted C.sub.1-4 -alkanoyl, C.sub.1-4 -alkenoyl, halogen-substituted C.sub.1-4 -alkenoyl, monohalogenopyrimidinyl, dihalogenopyrimidinyl or trihalogenopyrimidinyl which is bonded to A and/or B via ##STR2## and R.sub.5 is hydrogen or C.sub.1-4 -alkyl, Ka is a cation, m is 1, 2 or 3, n is 1 or 2 and the SO.sub.3.sup..crclbar. Ka group is bonded to A and/or B. These chromium complexes are suitable for dyeing nitrogen-containing or hydroxy-containing materials and they produce level dyeings having good all-round fastness properties.
