Tungsten, bis(acetonitrile)dicarbonylbis(triphenylphosphine)-, also known as bis(triphenylphosphine)bis(acetonitrile)dicarbonyltungsten(0), is a complex organometallic compound with the chemical formula C46H38N2O2P2W. It is a derivative of tungsten, featuring a central tungsten atom bonded to two carbonyl groups (CO), two acetonitrile molecules (CH3CN), and two triphenylphosphine ligands (PPh3). Tungsten, bis(acetonitrile)dicarbonylbis(triphenylphosphine)- is of interest in organometallic chemistry and catalysis, particularly in the field of homogeneous catalysis, where it can serve as a precursor to other tungsten-based catalysts. The presence of the triphenylphosphine ligands contributes to the stability and reactivity of the complex, making it a valuable tool in the synthesis of various organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 64738-62-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,3 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64738-62:
(7*6)+(6*4)+(5*7)+(4*3)+(3*8)+(2*6)+(1*2)=151
151 % 10 = 1
So 64738-62-1 is a valid CAS Registry Number.

PREPARATION, CHEMICAL AND STRUCTURAL STUDIES OF A NEW (η-ALLYL)DIHALOCARBONYLTUNGSTEN(II) COMPOUND

Boyer, M.,Daran, J. C.,Jeannin, Y.

, p. 177 - 186 (2007/10/02)

The complex (C2H5)4N (I) prepared from the anion W(CO)5Cl-, crystallizes in the triclinic system, P1, a 11.264(5), b 14.697(6), c 10.318(4) Angstroem; α 99.37(3), β 111.87(5), γ 90.21 deg; V 1559 Angstroem3; Z = 2.The structure was refined to R = 0.057 for 4509 independent reflections.The crystal is made up of discrete monomeric ions.In the anion the tungsten atom is at the center of an octahedron, with two chlorine atoms and two CO groups in the equatorial plane, and the two remaining apices occupied by a (η-allyl) ligand and atriphenylphosphine group.
