Abstract
The knowledge on the synthesis and structural features of lanthanide acylpyrazolonates, including tris-complexes, different-ligand complexes with aromatic N-heterocycles and phosphorus-containing ligands and anionic tetrakis-complexes is generalized. The effect of substituent in the acyl moiety on the structural and luminescence properties of the compounds is considered. The key features of acylpyrazolonate coordination polymers and lanthanide bis(acylpyrazolonates) are discussed. Bibliography — 71 references.
