Koordinatsionnaya Khimiya was founded in 1975 and is now one of the most prominent chemical journals in Russia. It presents reviews, original papers, and communications on all aspects of theoretical and experimental coordination chemistry. Modern coordination chemistry occupies a special interdisciplinary position in the chemical sciences, being at the junction of various fields and serving as a bridge between the inorganic, organic, physical, analytical, and biological branches of chemistry. The Russian school of coordination chemistry, which began as a creative friendship between A. Werner and L.Chugaev, has developed strong ties with leading western chemical schools. Russian chemists have contributed a great deal to the formation and growth of this field of chemistry and still play a leading role in the world chemical science. The materials published in the Russian Journal of Coordination Chemistry are meant not only for specialists in various fields of pure chemistry, but also for those working in related disciplines, such as chemical engineering, chemical analysis, molecular catalysis, ecology, biology, medicine, agriculture, materials science, hydrometallurgy, and energetics.
