The hydrothermal method was used to obtain two new compounds of Np(V): benzoate [(NpO₂)₃(py) (C₇H₅O₂)₃(H₂O)₂] (1) and salicylate [(NpO₂)(phen)(HOC₇H₄O₂)] (2), where py = pyridine and phen = 1,10-phenanthroline. An X-ray diffraction analysis of these compounds demonstrated that NpO⁺₂ cations are bound together by cation-cation bonds to form distorted squared networks in compound 1 and zigzag chains in 2.

Np（V）苯甲酸酯和水杨酸酯与含N分子配体的配合物中的阳离子间相互作用

使用水热法获得了两种新的Np（V）化合物：苯甲酸酯[（NpO ₂）₃（py）（C ₇ H ₅ O ₂）₃（H ₂ O）₂ ]（1）和水杨酸盐[[NpO ₂）（phen）（HOC ₇ H ₄ O ₂）]（2），其中py =吡啶，phen = 1,10-菲咯啉。该NPO这些化合物表现出的X射线衍射分析⁺ _2个阳离子通过阳离子阳离子键结合在一起，以形成扭曲平方网络在化合物1中和锯齿链2。
