Four new Np(V) perchlorate complexes of the composition [NpO(HO)]ClO (orthorhombic) (), [(NpO)(ClO)(HO)]ClO·HO (), (NpO)(UO)(HO) (), and [(NpO)Cl(HO)]ClO·2HO () have been synthesized and structurally characterized. The structure of previously known monoclinic modification of NpOClO·4HO () has been determined at 100 K. The coordination environment of Np and U atoms in compounds - is pentagonal bipyramids. A cation-cation (CC) interaction was found in structures -, in which the NpO ion manifests itself as a monodentate (, ) or bidentate (-) ligand. CC bonds play a fundamental role in the crystal structures of compounds , , and . They are the main structure-forming bonds that form the crystal package as a whole. The spectra of all compounds in the visible-near-IR range were measured.
已合成并对四种新的高氯酸盐配合物进行了结构表征，其组成为[ NpO(HO)]ClO（正交晶系）（）、[(NpO)(ClO)(HO)]ClO·HO（）、(NpO)(UO)(HO)（）和[(NpO)Cl(HO)]ClO·2HO（）。已在100 K下测定了先前已知的单斜晶系NpOClO·4HO（）的结构。化合物 - 中Np和U原子的配位环境为五角双锥。在结构 - 中发现了阳离子 - 阳离子（CC）相互作用，其中NpO离子表现为单齿（，）或双齿（ - ）配体。CC键在化合物 、 和 的晶体结构中起基本作用。它们是形成整个晶体堆积的主要结构形成键。测量了所有化合物在可见 - 近红外范围内的光谱。
