The extraframework sodium sulfide cationic cluster, Na₄S²⁺, has been introduced into zeolite Y (FAU, Si/Al = 1.56). A single crystal of |Na₇₃(Na₄S²⁺)_1.0|[Si₁₁₇Al₇₅O₃₈₄]-FAU was prepared by allowing aqueous 0.1 M Na₂S solution to flow past a |Na₇₅|[Si₁₁₇Al₇₅O₃₈₄]-FAU crystal, and followed by vacuum dehydration at 723 K. Its structure was determined by single-crystal synchrotron X-ray diffraction techniques in the cubic space group Fd\(\overline{3}\)m. The structure was refined using all intensities to the final error index R₁/wR₂ = 0.044/0.125. About 77 Na⁺ ions per unit cell are found at the crystallographically distinct positions, six. One Na⁺ ion per unit cell is at the center of double 6-ring. Two site-I′ positions are occupied by 26.5 and 4 Na⁺ ions, respectively, per unit cell. Thirty-two Na⁺ ions per unit cell are found at site II, in the supercage opposite single 6-rings. The remaining 4.5 and 9 Na⁺ ions per unit cell occupy two sites III′ near triple 4-rings in the supercage. Finally, one sulfide ion per unit cell, associated with Na⁺ ions, is found at the center of sodalite cavity. The 4 Na⁺ ions at site I′ coordinate to a sulfide ion at the center of sodalite cavity to give tetrahedral cationic cluster, Na₄S²⁺. In |Na₇₃(Na₄S²⁺)_1.0|[Si₁₁₇Al₇₅O₃₈₄]-FAU, tetrahedral Na₄S²⁺ ions center about 12.5% of the sodalite cavities.

骨架外的硫化钠阳离子簇Na ₄ S ²⁺已被引入到沸石Y中（FAU，Si / Al = 1.56）。通过使0.1 M Na ₂ S水溶液流过| Na ₇₅ | [Si ₁₁₇ Al ₇₅ ]，制得| Na ₇₃（Na ₄ S ²⁺）_1.0 | [Si ₁₁₇ Al ₇₅ O ₃₈₄ ] -FAU的单晶。O ₃₈₄ ] -FAU晶体，然后在723 K下真空脱水。通过单晶同步加速器X射线衍射技术确定立方空间群Fd \（\ overline {3} \）中的结构米。使用所有强度将结构精修到最终误差指数R ₁ / wR ₂  = 0.044 / 0.125。在晶体学上不同的位置发现每个晶胞约77个Na ⁺离子，六个。每个晶胞一个Na ⁺离子位于双6环的中心。每个晶胞分别占据26.5和4个Na ⁺离子的两个I-I'位置。在第二位超笼相对的单个6环中，在位点II中发现了每单位细胞32个Na ⁺离子。每个晶胞剩余的4.5和9 Na ⁺离子在超笼中的三重4环附近占据了两个位点III'。最后，每个晶胞一个硫离子，与Na ^+有关离子被发现在方钠石腔的中心。位置I'处的4个Na ⁺离子与方钠石腔中心的硫化物离子配位，得到四面体阳离子簇Na ₄ S ²⁺。在| Na ₇₃（Na ₄ S ²⁺）_1.0 | [Si ₁₁₇ Al ₇₅ O ₃₈₄ ] -FAU中，四面体Na ₄ S ²⁺离子居中于方钠石腔的约12.5％。
