A series of novel double salts of silver(I) were isolated by dissolving Ag(2)C(2) in a concentrated aqueous solution of R(F)CO(2)Ag (R(F) = CF(3), C(2)F(5)) and AgBF(4). Different ancillary solvento ligands such as H(2)O, CH(3)CN, and C(2)H(5)CN were found to affect the crystallization process that led to the assembly of various silver(I) cages with embedded C(2)(2-) ions. 2Ag(2)C(2) x 12CF(3)CO(2)Ag x 5H(2)O (1) consists of two independent C(2)@Ag(7) cages, each having the shape of a basket with a square base. Ag(2)C(2) x 6CF(3)CO(2)Ag x 3CH(3)CN (2) contains a zigzag chain of edge-sharing triangulated dodecahedra, and 4Ag(2)C(2) x 23CF(3)CO(2)Ag x 7C(2)H(5)CN x 2.5H(2)O (3) features an unusual double-walled silver column constructed from the fusion of four different kinds of irregular polyhedra. Ag(2)C(2) x 10C(2)F(5)CO(2)Ag x 9.5H(2)O (4), Ag(2)C(2) x 9C(2)F(5)CO(2)Ag x 3CH(3)CN x H(2)O (5), and Ag(2)C(2) x 6C(2)F(5)CO(2)Ag x 2C(2)H(5)CN (6) all contain an edge-sharing double cage with each single cage in the shape of a square antiprism, a capped square antiprism, and a triangulated dodecahedron, respectively.
通过将Ag₂C₂溶解在R(F)CO₂Ag（R(F) = CF₃、C₂F₅）和AgBF₄的浓水溶液中，分离出了一系列新型的银（I）复盐。发现不同的辅助溶剂配体，如H₂O、CH₃CN和C₂H₅CN，会影响结晶过程，从而导致组装出各种嵌入C₂²⁻离子的银（I）笼。2Ag₂C₂·12CF₃CO₂Ag·5H₂O（1）由两个独立的C₂@Ag₇笼组成，每个笼的形状都是底部为正方形的篮子。Ag₂C₂·6CF₃CO₂Ag·3CH₃CN（2）包含一条由共享边的三角十二面体组成的之字形链，4Ag₂C₂·23CF₃CO₂Ag·7C₂H₅CN·2.5H₂O（3）的特征是由四种不同类型的不规则多面体融合而成的不寻常的双壁银柱。Ag₂C₂·10C₂F₅CO₂Ag·9.5H₂O（4）、Ag₂C₂·9C₂F₅CO₂Ag·3CH₃CN·H₂O（5）和Ag₂C₂·6C₂F₅CO₂Ag·2C₂H₅CN（6）都包含一个共享边的双笼，每个单笼的形状分别为方形反棱柱、盖帽方形反棱柱和三角十二面体。
