The product formation depends on the water‐base molar ratio and the molar ratio of the starting materials. B(OH)<jats:sub>3</jats:sub> acts as a proton donor (Brønsted acid) rather than a hydroxide acceptor (Lewis acid). Ba(BO<jats:sub>2</jats:sub>OH) crystallizes in the non‐centrosymmetric orthorhombic space group <jats:italic>P</jats:italic>2<jats:sub>1</jats:sub>2<jats:sub>1</jats:sub>2<jats:sub>1</jats:sub>. Hydrogen bonds connect the almost planar (BO<jats:sub>2</jats:sub>OH)<jats:sup>2−</jats:sup> anions, which are isostructural to HCO<jats:sub>3</jats:sub><jats:sup>−</jats:sup>, into a syndiotactic chain. IR and Raman spectroscopy confirm the presence of hydroxide groups, which are involved in weak hydrogen bonds. Upon heating in air to about 450 °C, Ba(BO<jats:sub>2</jats:sub>OH) dehydrates to Ba<jats:sub>2</jats:sub>B<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub>. Moreover, the non‐centrosymmetric structure of Ba(BO<jats:sub>2</jats:sub>OH) crystals was verified with power‐dependent confocal Second Harmonic Generation (SHG) microscopy indicating large conversion efficiencies in ambient atmosphere.</jats:p>"}],"date_created":"2023-10-11T08:56:26Z","publisher":"Wiley","title":"Ba(BO2OH) – A Monoprotonated Monoborate from Hydroflux Showing Intense Second Harmonic Generation","issue":"21","quality_controlled":"1","year":"2022","user_id":"22501","_id":"47987","extern":"1","article_type":"original","article_number":" e2022001","type":"journal_article","status":"public","volume":648,"author":[{"full_name":"Li, Yuxi","last_name":"Li","first_name":"Yuxi"},{"full_name":"Hegarty, Peter A.","last_name":"Hegarty","first_name":"Peter A."},{"id":"22501","full_name":"Rüsing, Michael","last_name":"Rüsing","orcid":"0000-0003-4682-4577","first_name":"Michael"},{"full_name":"Eng, Lukas M.","last_name":"Eng","first_name":"Lukas M."},{"first_name":"Michael","last_name":"Ruck","full_name":"Ruck, Michael"}],"date_updated":"2023-10-11T08:59:51Z","oa":"1","doi":"10.1002/zaac.202200193","main_file_link":[{"open_access":"1","url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/zaac.202200193"}],"publication_identifier":{"issn":["0044-2313","1521-3749"]},"publication_status":"published","intvolume":"       648","citation":{"ama":"Li Y, Hegarty PA, Rüsing M, Eng LM, Ruck M.
