The chemical compound "(C20H8N4(C6H4CH3)4)NbOF" is a complex organic-inorganic hybrid molecule. It features a central niobium (Nb) atom, which is a transition metal, bonded to an oxygen (O) and a fluorine (F) atom. The niobium is also coordinated to a large organic ligand, which consists of a central C20H8N4 core with four substituent C6H4CH3 (tolyl) groups. This structure suggests that the compound may have unique electronic properties due to the combination of the metal center and the aromatic organic groups, potentially making it useful in areas such as catalysis or materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 81780-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,8 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81780-11:
(7*8)+(6*1)+(5*7)+(4*8)+(3*0)+(2*1)+(1*1)=132
132 % 10 = 2
So 81780-11-2 is a valid CAS Registry Number.

Crystal Structure of Fluoro(2,3,7,8,12,13,17,18-octaethylporphyrinato)oxoniobium; Demonstration of the Presence of Six-co-ordinated Niobium

Lecomte, Claude,Protas, Jean,Richard, Philippe,Barbe, Jean Michel,Guilard, Roger

, p. 247 - 250 (2007/10/02)

When HF is bubbled through a solution of (L=porphyrinate), porphyrinatoniobium oxide fluoride complexes are formed.The structures of some of these complexes have been studied from analytical and spectroscopic data.The title compound has been determined by X-ray diffraction methods.Crystals are monoclinic space group P21/c with a=15.007(3), b=22.257(4), c=10.058(2) Angstroem, β=77.85(2) deg, and Z=4.

Chemical and Electrochemical Preparation of Low Oxidation State Niobium Porphyrinates
