General Description

Potassium hexafluoronioabate, also known as potassium hexafluoronobate or potassium niobium hexafluoride, is a chemical compound with the molecular formula K2NbF6. It is a salt of potassium and hexafluoronioabate, and is commonly used in organic and inorganic synthesis, as well as in industrial applications such as in the production of specialty glasses and ceramics. Potassium hexafluoronioabate is also used in the field of electrochemistry as an electrolyte in certain applications. It is a white crystalline solid with a high melting point, and is soluble in water. This chemical compound is considered to be relatively low in toxicity and is not known to be harmful to the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 16919-14-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,1 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16919-14:
(7*1)+(6*6)+(5*9)+(4*1)+(3*9)+(2*1)+(1*4)=125
125 % 10 = 5
So 16919-14-5 is a valid CAS Registry Number.

Effects of alkyl chain length and anion size on thermal and structural properties for 1-alkyl-3-methylimidazolium hexafluorocomplex salts (C xMImAF6, x = 14, 16 and 18; A = P, As, Sb, Nb and Ta)

Xu, Fei,Matsumoto, Kazuhiko,Hagiwara, Rika

, p. 3494 - 3502 (2012)

A series of 1-alkyl-3-methylimidazolium hexafluorocomplex salts (C xMImAF6, x = 14, 16 and 18, A = P, As, Sb, Nb and Ta) have been characterized by thermal analysis, X-ray diffraction and polarized optical microscopy. A liquid crystalline mesophase is observed for all the C 16MIm and C18MIm salts. The C14MIm+ cation gives a liquid crystalline mesophase only with PF6 -. The temperature range of the liquid crystalline mesophase increases with an increase in alkyl chain length or with decrease in anion size. Single-crystal X-ray diffraction revealed that all the C18MImAF 6 salts (A = P, As, Sb, Nb and Ta) are isostructural with each other in the crystalline phase and have a layered structure. The interdigitated alkyl chain of the cation has a bent shape like a spoon near the imidazolium ring in the crystalline phase at -100 °C and is tilted with respect to the sheets of the imidazolium headgroups and anions. An increase of temperature increases the ratio of an all-trans conformation to the bent conformation in the crystalline phase. X-ray diffraction and polarized optical microscopy suggested that the liquid crystalline mesophase has a smectic A2 structure. The interlayer distance increases with a decrease in the anion size since the smaller anion has a stronger coulombic interaction with the imidazolium headgroup, resulting in the decrease of the interdigitated part to give a larger layer spacing.
