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 paper, a study has been made of a number of methods for the preparation of halide sulphides and halide selenides of molybdenum and tungsten in several oxidation states and the relative merits of the methods are discussed.
Abstract: A study has been made of a number of methods for the preparation of halide sulphides and halide selenides of molybdenum and tungsten in several oxidation states and the relative merits of the methods are discussed. The method of most general application is reaction of Sb2S3 or Sb2Se3 with the appropriate halide. In the case of WSCl4 the best preparative method is by reaction of sulphur with WCl6. Halide sulphides and selenides of molybdenum(IV) and tungsten(IV) are formed in the thermal decomposition of the corresponding quinquevalent compounds. The properties of these compounds are reported. Attempts to make similar tellurium compounds have been unsuccessful.

TL;DR: In this paper, the isolation of a large range of thio-, seleno-, and oxo-halides has been achieved by allowing Sb2Y3(Y = O, S, or Se) to react with a metal halide at room temperature with carbon disulphide as solvent.
