Inorganic Nitrogen Groups

Cyano-carbonyl complexes have been synthesized by the following routes  

Route (2) is that most used, but the final product often depends critically upon the choice of a thermal or photolytic process, the molar ratio of reactants, the reaction time and conditions. Behrens et al. used liquid 

Cryoscopic measurements on solutions of K4[Ni(CO) CN)j]2 (364), and the diamagnetism (370) indicated a dinuclear anion both in solution and the solid state, but the infrared spectrum was interpreted on the basis of both bridged carbonyl (365) and nonbridged structures (239). Recently the complex was shown to be an equimolar mixture of K2[Ni(CN)4] and K2[Ni 

Alkylation of cyano groups to form isonitrile complexes was achieved with alkyl bromides and iodides for the complexes [Tr-C5H5Fe(CO)(CN)2] [Eqs. (8) and (9)], [7t-C5H5M CO)3CN] (M = Mo, W), and [tt-CjHsMo 

Irradiation of M(CO)6 (M = Cr, Mo, W) with fulminate ions in THE solution produced the first low-valent fulminato derivatives, m-[M(CO)4 (CN0)2] - 51).

Perchlorates appear to fall into two broad categories those more4 or less5 sensitive to heat and shock. Included in the group of those qualitatively less sensitive are pure ammonium perchlorate, the alkali metal perchlorates, the alkaline earth perchlorates, and perchloryl fluoride. Among the more sensitive compounds are the pure inorganic nitrogenous... 

It was thought for a long time that in the ocean denitrihcation was the only mechanism of N2 production. However, most recently it was shown by two independent groups that large scale conversion of fixed inorganic nitrogen (nitrate, nitrite, ammonium) to N2 can occur through another important route, the so-called Anammox process [Eq. (1)] [21]. 

For maximum utility the encyclopedia has been arranged into five sections. Part I is an electromotive series. Part II lists tables of EMF values according to elements. Part III lists EMF values of common Inorganic anions. Part IV lists electrode potentials of various organic functional groups. Finally, Part V lists EMF data for the inorganic nitrogen bases, NH3 and NjH. ... 

Phosphorus, like nitrogen, is an essential constituent of living matter where it may be partly in combination (as phosphate groups) with organic groups, for example in lecithin and egg yolk, or mainly in inorganic form, as calcium phosphate(V), in bones and teeth. 

In Group 15 (V), nitrogen compounds readily form molecular compounds with BF. Phosphoms compounds also form adducts with BF. Inorganic or organic compounds containing oxygen form many adducts with boron trifluoride, whereas sulfur and selenium have been reported to form only a few (41—43). 

The importance of steric effects in determining the oxidation state of the product can be illustrated by a thioether linkage, eg (57). If a methyl group is forced to be adjacent to the sulfur bond, the planarity required for efficient electron donation by unshared electrons is prevented and oxidation is not observed (48). Similar chemistry is observed in the addition of organic nitrogen and oxygen nucleophiles as well as inorganic anions.
