Structure of Trimethylbenzylammonium and Triethylbenzylammonium Tetrachlorouranilates

(NH4)2[UO2Cl4]·2H2O, a new uranyl tetrachloride with ammonium charge-balancing cations

“…With respect to the CSD, there are numerous reports with ammonium-based charge-balancing species (Di Sipio et al, 1974a,b;Bois et al, 1976a,b;Rogers et al, 1987;Gatto et al, 2004;Schnaars & Wilson, 2013;Biswas et al, 2017;Serezkhina et al, 2021). Compound 1 has ammonium with a water molecule, while one report has ammonium with crown ethers (Rogers et al, 1987).…”

“…Compound 1 has ammonium with a water molecule, while one report has ammonium with crown ethers (Rogers et al, 1987). The other ammonium-based cations include organic-functional groups (Di Sipio et al, 1974a,b;Bois et al, 1976a,b;Gatto et al, 2004;Schnaars & Wilson, 2013;Biswas et al, 2017;Serezkhina et al, 2021). Other types of cations that charge-balance (UO 2 Cl 4 ) 2À in the CSD include pyridinium-based (Graziani et al, 1975;Bombieri et al, 1978;Marsh, 1988;Pospieszna et al, 2008;Deifel & Cahill, 2009;Baker et al, 2010;Andrews & Cahill, 2012;Lhoste et al, 2013;Hashem et al, 2013;Surbella III et al, 2016Carter et al, 2018;Mishra et al, 2019;Pyrch et al, 2020), phenanthroliniumbased (Di Sipio et al, 1981, imidazolium-based (Zalkin et al, 1983;Qu et al, 2014;Kohlgruber, 2022), and phosphoniumbased (Brown et al, 1996;Schnaars & Wilson, 2014) species.…”
