Title: The role of cation-cation interactions in a neptunyl chloride hydrate and topological aspects of neptunyl structural units

Abstract

The compound K{sub 4}(NpO{sub 2}){sub 3}Cl{sub 7}(H{sub 2}O){sub 4} was synthesized by evaporation of a Np{sup 5+}-bearing solution. The crystal structure was determined by single crystal X-ray diffraction and refined to R {sub 1}=0.0374. The compound is triclinic, P-1, a=8.882(1) A, b=12.082(2) A, c=12.403(2) A, {alpha}=65.855(2){sup o}, {beta}=69.604(2){sup o}, {gamma}=74.432(2){sup o}, V=1126.0(3) A{sup 3}, and Z=2. The structure contains dimers of edge sharing Np{sup 5+} pentagonal bipyramids that are linked into infinite chains through cation-cation interactions with an additional Np{sup 5+} pentagonal bipyramid. The structural units are linked through bonds to interstitial K cations and by H bonding. A graphical representation for neptunyl structural units including cation-cation interactions is introduced. - Graphical abstract: The structure of K{sub 4}(NpO{sub 2}){sub 3}Cl{sub 7}(H{sub 2}O){sub 4} contains neptunyl pentagonal bipyramids that are linked into chains through cation-cation interactions.
