COMPOUND CONTAINING MULTIMETAL COMPLEX, METAL COMPLEX AND METHOD OF THEIR PRODUCTION, METHOD OF PRODUCING CATALYST FOR EXGAUST GAS PURIFICATION THAT USES SAID COMPLEXES Russian patent published in 2010 - IPC B01J37/08 B01J37/02 B01J23/42 C07F15/00 

FIELD: process engineering.

SUBSTANCE: invention relates to compound that represents a multimetal complex comprising assemblage of metal complexes wherein ligand is coordinated by one metal atom or assemblage of atoms of one metal. Note here that assemblage of metal complexes are bound together by polydentant ligand which substitutes partially the ligands of metal complex assemblage and contains 2 to 1000 ligand atoms wherein each metal complex has carboxylic ligand and aforesaid polydentant ligand that represents dicarboxylic acid ligand, while metal is selected from the group consisting of Pt, Ni or Pd. Invention covers also the method of producing clusters of metal or metal oxide, the method of producing compound containing multimetal complex, and metal complex.

EFFECT: invention allows producing larger amount of controlled-size clusters.
