TL;DR: In this paper, the basic properties of molybdenum and the methods of producing metallic molybordenum are described, and the focus is directed to various applications of the molybenzenum alloys and compounds such as catalysts, lubricants and refractory ceramics.
Abstract: The basic properties of molybdenum and subsequently the methods of producing metallic molybdenum are described. Selected classes of important inorganic compounds (molybdenum halides, molybdenum oxides, iso- and hetero-polyoxomolybdates) as well as molybdenum hexacarbonyl and hybrid inorganic–organic materials are presented. Thereafter the focus is directed to various applications of metallic molybdenum, its alloys and compounds such as catalysts, lubricants and refractory ceramics. In conclusion, molybdenum’s medicinal role and the antimicrobial activity of MoO3 and solid solutions Mo

TL;DR: In this article, it was shown that chlorides can be intercalated in graphite from a solution of carbon tetrachloride if their solubility is in the range of 1 to 4 mg/ml in CCl4, at reflux temperature, in the presence of chlorine.
Abstract: Some chlorides, mainly of transition elements, can be intercalated in graphite from a solution of carbon tetrachloride if their solubility is in the range of 1 to 4 mg/ml in CCl4, at reflux temperature, in the presence of chlorine.The rate of extraction of intercalated salts with solvents has been compared to the rate of solution of these salts in the same solvents.

TL;DR: In this article, the cation [Fe(NCMe)6]2+ is formed from reactions in acetonitrile of iron metal with WF6, MoF6 and PF5, or the NO+ cation.
Abstract: The cation [Fe(NCMe)6]2+ is formed from reactions in acetonitrile of iron metal with WF6, MoF6, PF5, or the NO+ cation and from the reaction of iron(II) fluoride with PF5. Oxidation to FeIII is not observed using binary fluorides or NO+, but [Fe(NCMe)6]2+ is oxidised by chlorine in MeCN to give the tetrachloroferrate(III) anion. The MeCN co-ordinated to FeII is replaced by trimethyl phosphite giving [Fe(NCMe){P(OMe)3}5]2+ as the final product at room temperature. Some of the intermediate complexes in this reaction have been identified in solution by 31P{1H} n.m.r. spectroscopy.
