< sup > 53 </ sup > Cr is the radiogenic decay product of < sup > 53 </ sup > Mn.

Variations in < sup > 53 </ sup > Cr /< sup > 52 </ sup > Cr and Mn / Cr ratios from several meteorites indicate an initial < sup > 53 </ sup > Mn /< sup > 55 </ sup > Mn ratio that suggests Mn-Cr isotopic composition must result from in-situ decay of < sup > 53 </ sup > Mn in differentiated planetary bodies.

Tantalite ( Fe, Mn ) Ta < sub > 2 </ sub > O < sub > 6 </ sub > is the most important mineral for tantalum extraction.

Tantalite has the same mineral structure as columbite ( Fe, Mn ) ( Ta, Nb )< sub > 2 </ sub > O < sub > 6 </ sub >; when there is more Ta than Nb it is called tantalite and when there is more Nb than Ta is it called columbite ( or niobite ).

Other early structures included copper, calcium fluoride ( CaF < sub > 2 </ sub >, also known as fluorite ), calcite ( CaCO < sub > 3 </ sub >) and pyrite ( FeS < sub > 2 </ sub >) in 1914 ; spinel ( MgAl < sub > 2 </ sub > O < sub > 4 </ sub >) in 1915 ; the rutile and anatase forms of titanium dioxide ( TiO < sub > 2 </ sub >) in 1916 ; pyrochroite Mn ( OH )< sub > 2 </ sub > and, by extension, brucite Mg ( OH )< sub > 2 </ sub > in 1919 ;.

Rundle and Dahl discovered that Mn < sub > 2 </ sub >( CO )< sub > 10 </ sub > featured an “ unsupported ” Mn-Mn bond, thereby verifying the ability of metals to bond to one another in molecules.

An excess of manganese ( II ) salt, iodide ( I < sup >–</ sup >) and hydroxide ( OH < sup >–</ sup >) ions is added to a water sample causing a white precipitate of Mn ( OH )< sub > 2 </ sub > to form.

Some sources claim that Mn ( OH )< sub > 3 </ sub > is the brown precipitate, but hydrated MnO < sub > 2 </ sub > may also give the brown colour.

Generalized formula may be represented as Ba ( Mn < sup > 2 +</ sup >)( Mn < sup > 4 +</ sup >)< sub > 8 </ sub > O < sub > 16 </ sub >( OH )< sub > 4 </ sub > or as ( Ba, H < sub > 2 </ sub > O )< sub > 2 </ sub > Mn < sub > 5 </ sub > O < sub > 10 </ sub >.

A classic example is a dodecanuclear Manganese molecule with an effective spin of S = 10 derived from antiferromagnetic interaction on Mn ( IV ) metal centres with Mn ( III ) and Mn ( II ) metal centres .< ref >

There were five usable filter positions: 1265 Å-thick Al filter ( 2. 5 Å – 36 Å pass band ), Al / Mg / Mn filter ( 2. 4 Å – 32 Å ), 2. 52 μm Mg filter ( 2. 4 Å – 23 Å ), 11. 6 μm Al filter ( 2. 4 Å – 13 Å ), 119 μm Be filter ( 2. 3 Å – 10 Å ).

Columbite, also called niobite, niobite-tantalite and columbate, manganese | Mn ) niobium | Nb < sub > 2 </ sub > oxygen | O < sub > 6 </ sub >, is a black mineral group that is an ore of niobium.

While these DNAzymes have been demonstrated to be useful for constructing logic gates, they are limited by the need for a metal cofactor to function, such as Zn < sup > 2 +</ sup > or Mn < sup > 2 +</ sup >, and thus are not useful in vivo.

Wolframite, ( Fe, Mn ) WO < sub > 4 </ sub >, is an iron manganese tungstate mineral that is the intermediate between ferberite ( Fe < sup > 2 +</ sup > rich ) and huebernite ( Mn < sup > 2 +</ sup > rich ).

Unfortunately, not all the samples are suited for ESR dating: indeed, the presence of cationic impurities such as Mn < sup > 2 +</ sup >, Fe < sup > 2 +</ sup >, or Fe < sup > 3 +</ sup >, humic acids ( organic matter ), can mask the signal of interest, or interfere with it.

Cofactors can be divided into two broad groups: organic cofactors, such as flavin or heme, and inorganic cofactors, such as the metal ions Mg < sup > 2 +</ sup >, Cu < sup >+</ sup >, Mn < sup > 2 +</ sup >, or iron-sulfur clusters.

Many elements will have overlapping peaks ( e. g., Ti K < sub > β </ sub > and V K < sub > α </ sub >, Mn K < sub > β </ sub > and Fe K < sub > α </ sub >).

Tokyoite is a rare barium manganese vanadate mineral with the chemical formula: Ba < sub > 2 </ sub >( Mn < sup > 3 +</ sup >, Fe < sup > 3 +</ sup >) OH ( VO < sub > 4 </ sub >)< sub > 2 </ sub >.

The composition of pure pyrope is Mg < sub > 3 </ sub > Al < sub > 2 </ sub >( SiO < sub > 4 </ sub >)< sub > 3 </ sub >, although typically other elements are present in at least minor proportions -- these other elements include Ca, Cr, Fe and Mn.

One exception is potassium dimanganate ( III ), K < sub > 6 </ sub > Mn < sub > 2 </ sub > O < sub > 6 </ sub >, which contains discrete Mn < sub > 2 </ sub > O anions .< ref name =" Brachtel ">

Instead this oxidation stops at the level of Na < sub > 3 </ sub > MnO < sub > 4 </ sub >, and this Mn ( V ) salt is unstable in solution.
