The structure of Borax has really baffled me. Its formula is $\\ce{Na2B4O7.10H2O}$ and it is formulated as $\\ce{Na2[B4O5(OH)4].8H2O}$. 2 structures of Borax given on the internet are Can anybody
What is the IUPAC name of borax? - Chemistry Stack Exchange
2017年7月25日 · The name suggested here (via the question comments), the anion-corresponding part, ‘bicyclo[3.3.1]tetraboroxane-3,7-diolate’ ($\ce{[B4O5(O)2]^2-}$) obviously does not match with the tetraborate formula $\ce{[B4O5(OH)4]^2-}$ present in borax, whose structure, confirmed by X-ray crystallography, including hydrogens [1], is
What is the hybridisation of the bridging oxygen atoms in the …
Below is a neat looking borax anion. While exploring the molecule in a computer simulation (Gaussian 16, level of theory: HF/3-21G), I found that the oxygen atoms in the 8-membered outer ring had sp 2 hybrid orbitals. My curiosity led me to question the presented data. Using Natural Bond Orbital analysis, I found out that:

2019年12月23日 · The tetrahedrally coordinated structure proposed by Berger was also puzzling because in various borate systems there is a regular variation of the fraction of boron atoms in fourfold coordination as a function of increasing alkali content (both in glasses and crystals); yet in each instance there was an obvious trend towards only threefold ...

2012年6月1日 · Borax decahydrate (BDH), $\ce{Na2B4O7.10H2O}$ is easily dehydrated to Borax pentahydrate (BPH), $\ce{Na2B4O7.5H2O}$ without much visible change. The actual form of the borate ion in both BDH and BPH is $\ce{B4O5(OH)4^2-}$ with 2 of the water molecules actually incorporated as hydroxyl groups in the ion.
Reaction of borax with NaOH - Chemistry Stack Exchange
2019年5月11日 · The name borax is derived from the Persian word borak, meaning white. IUPAC name of borax is sodium tetraborate decahydrate ( $\ce{Na2B4O7.10H2O}$ ). Also note that, after analyzing its crystal structure, borax is more properly formulated as $\ce{Na2[B4O5(OH)4].8 H2O}$ and given its systematic name 2,4,6,8,9-pentaoxa-1,3,5,7-tetraborabicyclo[3. ...

Water of Crystallisation in Borax and Copper Sulphate
2024年1月2日 · The formula for borax is written as $\ce{Na2B4O7.10H2O}$ and also as $\ce{Na2[B4O5(OH)4].8H2O}$. From the structure, it obvious from where the 2nd formula comes. But the question I have is, what is the water of crystallisation in Borax, 8 or 10?
Why is a borax solution basic? - Chemistry Stack Exchange
2024年7月25日 · Borax (Ref.1 with crystal structure) is a complicated molecule (also see here).I'd like to redirect you to my answer here, which confirms Mithoron's comment about the correct anion of borax, $\ce{[B4O5(OH)4]^2-}$ (in addition to Wikipedia article about borax).
The acidity of boric acid - Chemistry Stack Exchange
Another clue that boric acid may be a special case is that its structure doesn't conform to the octet rule (for Boron) This is unlike some of the other acids, even when some of those , like for example sulfuric acid,are usually portrayed as having 10 or more electrons around the central atom instead of 8. As is written in the Wikipedia page ...
