Trimethyl-[[2,3,4,5,6-pentakis(trimethylsilylmethyl)phenyl]methyl]silane is a complex organosilicon compound characterized by a central silicon atom bonded to three methyl groups and a phenyl group. The phenyl ring is further substituted with five trimethylsilylmethyl groups, which are themselves composed of a silicon atom bonded to three methyl groups and a methyl group. This molecule is known for its unique structure and potential applications in the field of organosilicon chemistry, particularly in the synthesis of complex silicon-containing compounds and materials. Its highly branched and symmetrical structure makes it an interesting subject for study in terms of its physical and chemical properties, as well as its potential use in specialized applications where such a unique molecular architecture is beneficial.

64131-87-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64131-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,1,3 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64131-87:
(7*6)+(6*4)+(5*1)+(4*3)+(3*1)+(2*8)+(1*7)=109
109 % 10 = 9
So 64131-87-9 is a valid CAS Registry Number.

Structures and Molecular Properties of Sterically Overcrowded Molecules, 37. - Hexakis(trimethylsilylmethyl)benzene C66

Bock, Hans,Meuret, Jochen,Ruppert, Klaus

, p. 2237 - 2242 (2007/10/02)

Both the low first vertical ionization energy of only 7.40 eV, determined by PE spectroscopy for C66, and the blocked substituent rotation in its radical cation as proven by ESR/ENDOR spectroscopy suggest considerable steric overcrowdedness.To further substantiate this interpretation of the molecular properties, the crystal structure (hexagonal R, Z = 2) has been determined at 100 K.Accordingly, the bulky trimethylsilyl groups are arranged alternatingly above or below the C6-ring plane, out of which the methylene C centers are twisted by +/- 9 deg.Due to the angles CCSi widened to 115 deg, however, the intramolecular distances C(H)...(H)C between non-neighboured methyl groups of 443 and 452 pm even slightly exceed their van der Waals radii sum of 400 pm and thus avoid severe spatial congestion. - Key Words: Sterically overcrowded organosilicon molecules/ Radical cation dynamics/ Silicon compounds
