Novel carboxylic acid metal salt/amine complexes are prepared by reacting 1 mol of a carboxylic acid metal salt of the formula (A(-))2ME2+ in which A(-) is the anion of a carboxylic acid which contains polar substituents or radicals and in particular contains an amide or imide grouping, such as a halogenoacetic acid, nitrilo-, cyano- or ureido-acetic acid, monoamidosuccinic acid, succinimidyl- or maleimidyl-alkanecarboxylic acid, benzenesulphonic acid or pyrrolidone-5-carboxylic acid, and Me2+ is a divalent metal cation, with 1 mol of a diamine of the formula R1-NH-R-NH-R2 in which R is an aliphatic radical having not more than 7 C atoms or is a cycloaliphatic radical and R1 and R2 are hydrogen, alkyl having 1 to 4 C atoms, cyclohexyl, benzyl, 2-aminoethyl or 3-aminopropyl, in a polar organic solvent and in the temperature range from 25 DEG to 200 DEG C., to give complex compounds. The novel complex compounds are suitable as catalytic curing agents for epoxide resins.
