Abstract: The basic architectural motif of the title compound, [Cu₂(C₂H₃O₂)₄(C₄H₅N₃)], is a chain of alternating tetrakis(-acetato)dicopper(II) and 2-aminopyrimidine moieties in which square-pyramidal copper(II) centres are alternately linked by four bridging acetate anions [Cu-O = 1.947  (2)-1.984  (2)  Å] and a single bridging 2-aminopyrimidine molecule [Cu-N 2.214  (2)  Å]. N-HO and C-HO hydrogen bonds support the Cu-N coordination to generate the chains, which align perpendicular to the (10) plane. The dinuclear copper unit has crystallographic inversion symmetry, and the 2-aminopyrimidine bridging ligand has twofold rotation symmetry.
