亚硒酸钕

亚硒酸钕是一种无机化合物，化学式为Nd2(SeO3)3，它的溶度积为(1.5±0.9)×10−32。它的热分解经Nd2SeO5，最终得到氧化钕。Milagros de Pedro; Renée Enjalbert; Alicia Castro; Jean-Christian Trombe; Jean Galy (1994). Synthesis, Characterization, and Crystal Structure of Nd(HSeO3)(SeO3) · 2H2O. Journal of Solid State Chemistry, 108(1), 87–93. .
制备
它可由弱酸性的氯化钕和亚硒酸钠在溶液中反应得到。Perkovakaya, Yu. B. Lanthanum, cerium, praseodymium, and neodymium selenites. Metody Polucheniya Khimicheskikh Reaktivov i Preparatov, 1967. 16. 116-119. . .硝酸钕和二氧化硒在230 °C与水中进行水热反应，可以得到亚硒酸钕，但反应会同时生成Nd2(SeO4)(SeO3)2(H2O)2。Yaxing Wang; Huangjie Lu; Xing Dai; et al.
