TL;DR: Specific reaction parameters and considerations will be pointed out showing that a deliberate pure inorganic supramolecular chemistry based on weak interactions, flexibility and dynamic is possible with polyoxometalates.
Abstract: The present tutorial review reports on the synthetic approaches for the formation of “polyoxothiometalate” compounds with special emphasis on the unique reactivity of the preformed sulfur-containing cationic building blocks {Mo2O2S2}2+ and {Mo3S4}4+ toward polyoxometalate building blocks. Such simple chemical systems, based on chemical and structural complementarities between ionic reactive moieties have led to the synthesis of a series of relevant clusters with unrivalled large nuclearity structural arrangements, such as loops, triangles, squares and boxes. Specific reaction parameters and considerations will be pointed out showing that a deliberate pure inorganic supramolecular chemistry based on weak interactions, flexibility and dynamic is possible with polyoxometalates.

TL;DR: In this paper, four cis-dioxomolybdenum complexes of general formula [MoO2(Ln)EtOH] (n = 1/4) with potentially tridentate Schiff bases derived from 5-methyl pyrazole-3-carbohydrazide and salicylaldehyde/substituted salicity-aldehyde/o-hydroxy acetophenone have been prepared.

TL;DR: An overview is provided of the molybdenum‐ and tungsten‐containing enzymes that catalyze the interconversion of formate and CO2, focusing on common structural and mechanistic themes, as well as a consideration of the manner in which the mature Mo‐ or W‐containing cofactor is inserted into apoprotein.

TL;DR: In this paper, an extraction study of molybdenum (VI) by 30% tri-n-butyl phosphate in n-dodecane and 0.2 M octyl (phenyl)-N, N-di-isobutyl carbamoylmethylphosphine oxide in 30% Tri-nbutyl Phosphine extraction systems was performed from aqueous solution containing HCl, HNO3 and acetohydroxamic acid.
Abstract: The extraction study of molybdenum (VI) by 30% tri-n-butyl phosphate in n-dodecane and 0.2 M octyl (phenyl)-N,N-di-isobutylcarbamoylmethylphosphine oxide in 30% tri-n-butyl phosphate extraction systems was performed from aqueous solution containing HCl, HNO3 and acetohydroxamic acid. Depending on extraction conditions, acetohydroxamic acid can significantly affect the speciation of molybdenum and can increase or decrease its distribution ratio. Our investigation confirmed the strong ability of the acetohydroxamic acid to form complexes with Mo even in highly acidic solutions. UV absorption spectra confirmed that a fraction of the Mo(VI)-AHA species can be present in the organic phase after extraction.
