Sumario:The structure of the title compound, poly[triaquatetra-μ-cyanido-tetracyanidobis­(1,4,10,13-tetra­oxa-7,16-diaza­cyclo­octa­deca­ne)di­barium(II)tetra­gold(I)], [Au(4)Ba(2)(CN)(8)(C(12)H(26)N(2)O(4))(2)(H(2)O)(3)](n), displays O—H⋯N hydrogen bonding between water molecules and cyano ligands and an unusual pattern of aurophilic inter­actions 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 inter­actions.
