Abstract: The title compound, [Cu₄(-Mo₈O₂₆)(C₁₀H₈N₂)₄]_n, is a two-dimensional 3,4-connected network coordination polymer containing two crystallographically distinct T-coordinated Cu^I atoms, each of which is bound to two N atoms from two bridging 2,4'-bipyridine ligands and a terminal O atom belonging to a centrosymmetric -octamolybdate anion. Rippled cationic [Cu(2,4'-bpy)]_nⁿ⁺ chain motifs are linked into `brick-wall' two-dimensional layers by exo-tetradentate -octamolybdate anions. The layers stack via C-HO interactions to form a three-dimensional structure.
