Antimony pentaphenyl, also known as pentaphenylantitmon, is a chemical compound with the formula (C6H5)5Sb. It is a derivative of antimony, a metalloid element, where five phenyl groups (C6H5) are attached to a central antimony atom. Antimony, pentaphenyl- is characterized by its stability and is often used in organic synthesis as a reagent or a precursor for the preparation of other antimony-containing compounds. Antimony pentaphenyl is typically synthesized through the reaction of antimony trichloride with phenylmagnesium bromide. It is an important compound in the field of organometallic chemistry and has potential applications in materials science and pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 2170-05-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2170-05:
(6*2)+(5*1)+(4*7)+(3*0)+(2*0)+(1*5)=50
50 % 10 = 0
So 2170-05-0 is a valid CAS Registry Number.

Geometry of Pentaphenylantimony in Solution: Support for a Trigonal Bipyramidal Assignment from X-ray Absorption Spectroscopy and Vibrational Spectroscopic Data

George, Graham N.,Johnstone, Timothy C.,Le Magueres, Pierre,Lindquist-Kleissler, Brent,Weng, Monica

, p. 8566 - 8574 (2021/06/28)

Pentaphenylantimony (SbPh5) has been previously crystallized in either a square pyramidal or trigonal bipyramidal geometry. Investigation of the solution-state structure of SbPh5 has been hampered by the extreme fluxionality of this compound, but previous vibrational spectroscopic studies concluded that it maintains a square pyramidal geometry in solution. This non-VSEPR-compliant geometry, which is also assumed by BiPh5 in the solid state, stands in contrast to the trigonal bipyramidal geometries of PPh5 and AsPh5. A range of phenomena have been invoked to explain this discrepancy, most notably, the increased importance of relativistic effects as group 15 is descended. We present crystallographic, spectroscopic, and computational data revealing that SbPh5 in fact assumes the VSEPR-compliant trigonal bipyramidal geometry in solution. In particular, Sb X-ray absorption spectroscopy (XAS) was used to obtain geometry-sensitive spectra that do not suffer from the slow spectroscopic time scale that has prevented NMR studies from elucidating the structure of this fluxional molecule. Sb K-edge and LIII-edge XAS spectra of crystalline solids featuring SbPh5 in either a square pyramidal (nonsolvate) or trigonal bipyramidal (cyclohexane hemisolvate or THF hemisolvate) form were compared to spectra of SbPh5 in solution. The solution-state spectra agree with those from solids containing trigonal bipyramidal SbPh5. The most diagnostic spectroscopic feature was the distribution of intensity in the Sb LIII pre-edge features. These distributions were rationalized using time-dependent density functional theory calculations that take into account spin-orbit coupling. Our use of Sb XAS not only resolves a long-standing physical inorganic question but also demonstrates more widely the utility of XAS in establishing the structures of fluxional main-group compounds. This conclusion was further supported by solid- and solution-state Raman data. Finally, we note that the present high-resolution diffraction data allow τ for nonsolvated SbPh5 to be revised to 0.216.

Synthesis and structure of fluorinated tetraphenylantimony β-diketonates
