The A.N. Nesmeyanov Institute of Organoelement Compounds of Russian Academy of Sciences (INEOS RAS) (Russian: Институт элементоорганических соединений Российской Академии Наук им. А.Н. Несмеянова (ИНЭОС РАН)) was founded in 1954 by a prominent scientist, the President of the USSR Academy of Sciences, academician A. N. Nesmeyanov (1899–1980), who was a "father" of the modern chemistry of organoelement and organometallic compounds. He headed the Institute for 26 years. Major directions of research of the Institute are the following: Laboratories of Organoelement Profile, Laboratories of Polymer Profile, and Laboratories of Physical Profile.
The successors of A.N. Nesmeyanov as directors of the Institute were the Members of the Academy of Sciences of USSR and afterwards the Members of the Russian Academy of Sciences:
At present INEOS RAS is a large research centre having ~660 employees with 564 scientific researchers of various levels. 77 Professors, holding Doctor of Science (Dr. Sci.) degree, and 248 researchers having PhD degree are actively working at INEOS RAS.
INEOS RAS is an internationally recognized research establishment, where the chemistry of organoelement and macromolecular compounds is developed. Its reputation as a scientific centre in chemistry is very high both in Russia and abroad. Many outstanding scientists who initiated new directions in organic and organoelement chemistry, polymer chemistry, physical chemistry, and physics, such as K.A. Andrianov, I.L. Knunyants, V.V. Korshak, I.V. Obreimov, M.E. Vol’pin, M.I. Kabachnik, O.A. Reutov, D.N. Kursanov, Yu.T. Struchkov, R.Kh. Freydlina, A.I .Kitaigorodsky, T.A. Mastryukova, M.Yu. Antipin and many others have been fruitfully working at INEOS RAS.
For recent years the scientific activities of the Institute have been supported by ~20 international grants (7th European Commission program, Swiss National Science Foundation (SNCF), Deutsche Forschungsgemeinschaft (DFG), etc.), 50-60 grants from the Russian Foundation for Basic Research (RFBR), more than 50 grants from the Presidium of the RAS and Department of Chemistry and Material Sciences of the RAS. INEOS is also incorporated in six Federal Scientific and Technical Programmes. Six young scientists received personal Grants from the President of Russian Federation for Government support of Young Russian Scientists and four scientists received the grants from Foundation for Russian Science Support.
