The structure of the title compound, poly[triaquatetra-μ-cyanido-tetracyanidobis-(1,4,10,13-tetra-oxa-7,16-diaza-cyclo-octa-deca-ne)di-barium(II)tetra-gold(I)], Au(4)Ba(2)(CN)(8)(C(12)H(26)N(2)O(4))(2)(H(2)O)(3), displays O-H⋯N hydrogen bonding between water molecules and cyano ligands and an unusual pattern of aurophilic inter-actions that yields a monomer, dimer, and trimer of Au(CN)(2) within the same crystal structure. In two of the five Au positions, the atom resides on a center of inversion. The overall arrangement is that of a coordination polymer assisted by aurophilic and hydrogen-bonded inter-actions.
标题化合物聚[三水四-μ-氰基-四氰基双-(1,4,10,13-四氧杂-7,16-二氮杂环十八烷)二钡(II)四金(I)]，Au(4)Ba(2)(CN)(8)(C(12)H(26)N(2)O(4))(2)(H(2)O)(3)的结构显示水分子与氰基配体之间存在O-H⋯N氢键，以及一种不寻常的亲金相互作用模式，在同一晶体结构中产生了Au(CN)(2)的单体、二聚体和三聚体。在五个金位置中的两个位置上，原子位于对称中心。整体排列是由亲金相互作用和氢键相互作用辅助的配位聚合物的排列。
