Chemist. Nikolai Semyonovich Kurnakov ( Russian: Николай Семёнович Курнаков; 6 December [ O.S. 24 November] 1860 – 19 March 1941) was a Russian chemist, who is internationally recognized as the originator of physicochemical analysis. He also was one of the principal founders of the platinum industry in the Soviet Union.
Transition metal carboxylate complexes are coordination complexes with carboxylate (RCO 2−) ligands. Reflecting the diversity of carboxylic acids, the inventory of metal carboxylates is large. Many are useful commercially, and many have attracted intense scholarly scrutiny. Carboxylates exhibit a variety of coordination modes, most common are ...
Structure of an η 2 -formaldehyde complex. Transition metal complexes of aldehydes and ketones describes coordination complexes with aldehyde (RCHO) and ketone (R2CO) ligands. Because aldehydes and ketones are common, the area is of fundamental interest. Some reactions that are useful in organic chemistry involve such complexes.
Illustrative coordination complexes of thiosulfate. Thiosulfate is a potent ligand for soft metal ions. A typical complex is [Pd(S 2 O 3) 2 (ethylenediamine)] 2−, which features a pair of S-bonded thiosulfate ligands. Simple aquo and ammine complexes are also known.
Ilya Chernyaev. Ilya Ilich Chernyaev (21 January 1893 – 30 September 1966) was a Russian and Soviet chemist who worked on inorganic chemistry and identified what is termed in coordination chemistry as the trans effect. He was a specialist on the refining of rhodium, palladium, platinum and other precious metals.
Viktor Aleksandrovich Kogan was born on 9 August 1936. In 1959 he graduated from the Chemical Faculty of Rostov State University. Since 1962 he worked at the RSU; since 1978 he was a Professor, in 1983—2014 he was the Head of the Department of Physical and Colloid Chemistry of the RSU (now Southern Federal University ). [1]
Geometry index. In coordination chemistry and crystallography, the geometry index or structural parameter ( τ) is a number ranging from 0 to 1 that indicates what the geometry of the coordination center is. The first such parameter for 5-coordinate compounds was developed in 1984. [1] Later, parameters for 4-coordinate compounds were developed.
Octahedral complexes. trans - [MCl 2 (pyridine) 4] n+ is a common type of transition metal pyridine complex. Chloro (pyridine)cobaloxime. Crabtree's catalyst. Owing to the relatively wide C-N-C angle, the 2,6-hydrogen atoms interfere with the formation of [M (py) 6] z complexes. A few octahedral homoleptic pyridine complexes are known.
