Manganese(II) sulfate usually refers to the inorganic compound with the formula MnSO 4 ·H 2 O. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260,000 tonnes of manganese(II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds.
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
The name DuPhos is derived from the chemical company that developed this type of ligand (DuP, DuPont) and the compound class of phospholanes (Phos) it belongs to. FOOF Dioxygen difluoride , O 2 F 2 , an extremely unstable compound which reacts explosively with most other substances – the nickname "FOOF" is a play on its formula.
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound.The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. For relatively simple ...
Compounds with oxidation states +5 are somewhat elusive, and often found associated to an oxide (O 2−) or nitride (N 3−) ligand. [29] One example is the blue anion hypomanganate [MnO 4] 3−. [30] Mn(IV) is somewhat enigmatic because it is common in nature but far rarer in synthetic chemistry. The most common Mn ore, pyrolusite, is MnO 2.
Although most compounds are referred to by their IUPAC systematic names ... hydroxide – Mn(OH) 2; Manganese(II) oxide – MnO;
The first borosulfate to be discovered was K 5 [B(SO 4) 4] in 2012 by the research group of Henning Höppe, [1] [2] although the compound class as such had been postulated already in 1962 by G. Schott and H. U. Kibbel. [3] Over 80 unique compounds are known as of 2024.
