Tris(trimethylsilyl)heptaphosphine, also known as (Me3Si)3P7, is a unique organophosphorus compound characterized by its heptaphosphorus (seven phosphorus atoms) core and three trimethylsilyl (Me3Si) groups. This molecule is of interest in the field of inorganic chemistry, particularly for its potential applications in the synthesis of new materials and compounds. The structure of tris(trimethylsilyl)heptaphosphine is complex, featuring a central P7 ring with the trimethylsilyl groups attached to three of the phosphorus atoms. This arrangement gives the molecule distinct electronic and steric properties, which can influence its reactivity and stability. The compound is synthesized through a multi-step process and is typically handled under controlled conditions due to its sensitivity to air and moisture. Research on tris(trimethylsilyl)heptaphosphine and related phosphorus-rich compounds contributes to the understanding of phosphorus chemistry and may lead to the development of novel phosphorus-containing materials with applications in various industries.

Check Digit Verification of cas no

The CAS Registry Mumber 57990-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,9 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57990-97:
(7*5)+(6*7)+(5*9)+(4*9)+(3*0)+(2*9)+(1*7)=183
183 % 10 = 3
So 57990-97-3 is a valid CAS Registry Number.

Mono- and dinuclear tetraphosphabutadiene ferrate anions

Reduction of [CpArFe(μ-Br)]2 (1, CpAr = C5(C6H4-4-Et)5) by potassium napthalenide, followed by the addition of white phosphorus, affords [K(18-c-6){CpArFe(η4-P4)}] (2, 18-c-6 = [18]crown-6), which features a planar cyclo-P42- ligand. The related diiron complex [Na2(THF)5(CpArFe)2(μ,η4:4-P4)] (3) was obtained by reducing 1 with sodium amalgam in the presence of P4. Protonation of 3 affords [Na(THF)3][(CpArFe)2(μ,η4:4-P4)(H)] (4), while the reaction of 3 with trimethylchlorosilane gives the nortricyclane compound P7(SiMe3)3 as the main product.
