Na2B4O7OH4

Na2B4O7OH4 is a chemical formula associated with the boron-oxygen-sodium family, related to borates. The exact nature of a compound described by this stoichiometry is not widely documented in standard references, and there is little published information on a well-characterized solid with this exact composition. In some contexts it is interpreted as Na2B4O7(OH)4, a neutral tetraborate framework bearing four hydroxyl groups, though the precise structure and charge balance would depend on hydration and synthesis conditions.

Composition and structure: The tetraborate unit B4O7 is common in sodium borates, typically forming B4O7^2− in salts such as sodium tetraborate. Substituting oxygens with hydroxyl groups or protonating the framework can alter connectivity and charge. Without crystallographic or spectroscopic data, the specific arrangement of sodium ions and the B–O network in Na2B4O7OH4 cannot be stated with confidence.

Occurrence and preparation: There are no widely cited, standalone preparations of a compound explicitly labeled Na2B4O7OH4. References, if any, would likely describe hydroxy-substituted derivatives of sodium tetraborate produced under particular solution or decomposition conditions rather than a discrete, well-defined mineral or crystal.

Applications and safety: Practical uses would depend on the compound’s stability, solubility, and reactivity, which are not established in a standard reference. Handling would follow general borate safety practices, including avoidance of inhalation and contact with skin or eyes, and adherence to typical laboratory or industrial guidelines for borate compounds.
