{"abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p>Pure samples of colorless, air‐stable Ba(BO<jats:sub>2</jats:sub>OH) crystals were obtained from Ba(NO<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub> and H<jats:sub>3</jats:sub>BO<jats:sub>3</jats:sub> under the ultra‐alkaline conditions of a KOH hydroflux at about 250 °C. 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>"}],"extern":"1","title":"Ba(BO2OH) – A Monoprotonated Monoborate from Hydroflux Showing Intense Second Harmonic Generation","date_updated":"2023-10-11T08:59:51Z","issue":"21","intvolume":"       648","volume":648,"publication_identifier":{"issn":["0044-2313","1521-3749"]},"main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/zaac.202200193","open_access":"1"}],"author":[{"first_name":"Yuxi","last_name":"Li","full_name":"Li, Yuxi"},{"first_name":"Peter A.","full_name":"Hegarty, Peter A.","last_name":"Hegarty"},{"orcid":"0000-0003-4682-4577","last_name":"Rüsing","full_name":"Rüsing, Michael","first_name":"Michael","id":"22501"},{"full_name":"Eng, Lukas M.","last_name":"Eng","first_name":"Lukas M."},{"full_name":"Ruck, Michael","last_name":"Ruck","first_name":"Michael"}],"publication_status":"published","doi":"10.1002/zaac.202200193","date_created":"2023-10-11T08:56:26Z","publication":"Zeitschrift für anorganische und allgemeine Chemie","language":[{"iso":"eng"}],"quality_controlled":"1","keyword":["Inorganic Chemistry"],"type":"journal_article","oa":"1","publisher":"Wiley","article_number":" e2022001","citation":{"mla":"Li, Yuxi, et al. “Ba(BO2OH) – A Monoprotonated Monoborate from Hydroflux Showing Intense Second Harmonic Generation.” <i>Zeitschrift Für Anorganische Und Allgemeine Chemie</i>, vol. 648, no. 21, e2022001, Wiley, 2022, doi:<a href=\"https://doi.org/10.1002/zaac.202200193\">10.1002/zaac.202200193</a>.","chicago":"Li, Yuxi, Peter A.
