Mercury(II) hydroxide molecules have been prepared upon mercury arc lamp irradiation of Hg, H(2), and O(2) mixtures in solid neon and argon. The strongest three infrared absorptions are identified through isotopic substitution (D(2), HD, (18)O(2), (16)O(18)O) and comparison to frequencies from DFT calculations. The isolated Hg(OH)(2) molecule is stable and has a linear O-Hg-O linkage in a C(2) structure
汞(II)氢氧化物分子是在
汞弧灯照射下在固态
氖气和
氩气中的Hg,H(2)和O(2)混合物辐照后制得的。通过同位素取代(D(2),HD,(18)O(2),(16)O(18)O)并与DFT计算的频率进行比较,可以确定最强的三种红外吸收。分离的Hg(OH)(2)分子是稳定的,并且在具有86度二面角的C(2)结构中具有线性O-Hg-O键。但是,在
水溶液中,Hg(2+)和2OH(-)可能会形成Hg(OH)(2)中间体,该中间体会消除
水并沉淀出固态HgO:固态Hg(OH)(2)化合物是未知的。
