The present patent application relates to new metal complexes having at least one N-aminoguanidinate ligand. The patent application further relates to the preparation of the new metal complexes and also to their use. The new metal complexes are especially suitable as precursors for the preparation of functional layers by means of gas-phase thin-film processes such as CVD, MO-CVD, MOVPE and ALD. Additionally, they are also suitable as catalysts for olefin hydroamination and for olefm polymerization.

The present invention relates to an alternative co-substrate of ketoglutaric acid-dependent dioxygenases for functional production and control of same, with the aim of achieving therapeutic effects against cancer, neurodegenerative diseases and age related diseases. Epigenetically induced diseases caused by dysregulation and in particular also by metabolic dysfunction in the citric acid cycle are likewise targeted by this therapy.

Embodiments of the present invention provide for syntheses and uses of tri-substituted mono-hydrogen ferrocyanides for efficient hydroxyl radical generators. For example, the present invention provides for the syntheses of mono-hydrogen ferrocyanides of the general formula M.sub.3HFe(CN).sub.6 in which iron has an oxidation number of +2 (ferro) and the positive counter-ion, M, belongs mainly to the group of the alkali metals such as Na+, K+ and Li+, or to organic alkyl cations such as imidazole derivatives.

Macrocyclic complexes and macrocyclic compounds. The macrocyclic complexes or macrocyclic compounds have a TACN moiety with one or more amine group(s) or a O- or S-substituted TACN moiety. The macrocyclic complexes have a high-spin Fe(III) atom coordinated to the TACN moiety. The macrocyclic complexes can be used in imaging methods.

A process for producing a bimetallic, terephthalate metal organic framework (MOF) having a flexible structure and comprising aluminum and iron cations, comprises contacting a water-soluble aluminum salt, a chelated iron compound and 1,4-benzenedicarboxylic acid or a salt thereof with a fluoride-free mixture of water and a polar organic solvent at a reaction temperature of less than 200° C. to produce a solid reaction product comprising the MOF.
