The chemical compound "W2(C5H4C5H4)(C2(C6H5)2)2(CO)3" is a complex organometallic compound consisting of two tungsten atoms. Each tungsten atom is coordinated to a cyclopentadienyl ligand (C5H4), which is a five-membered ring with alternating single and double bonds, and a diphenylacetylene ligand (C2(C6H5)2), which is an acetylene derivative with two phenyl groups attached. Additionally, each tungsten atom is also coordinated to three carbonyl groups (CO). The compound features a sandwich-like structure with the two tungsten atoms at the center, surrounded by the ligands, and is known for its stability and unique electronic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 89618-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,1 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89618-51:
(7*8)+(6*9)+(5*6)+(4*1)+(3*8)+(2*5)+(1*1)=179
179 % 10 = 9
So 89618-51-9 is a valid CAS Registry Number.

First photosubstitution chemistry of fulvalene-bridged metal-metal bonded carbonyls. Synthesis and structural determination of novel homo- and heterobimetallic alkyne complexes

Drage, James S.,Tilset, Mats,Vollhardt, Peter C.,Weidman, Timothy W.

, p. 812 - 814 (1984)

Irradiation of the carbonyl(η5:η5-fulvalene)di-metal complexes of molybdenum, tungsten, and ruthenium 1, 3, and 4 in the presence of alkynes gives not only complexes of different respective composition and structure within the series but also in comparison with the corresponding (η5-cyctopentadienyl)metal carbonyl dimers. (η5:η5-C10H8)(CO) 5MoRu (5) furnishes a novel reactive dinuclear (alkyne)metal oxo complex.
