Abstract

The compound having an empirical formula Cu₈C₂₄H₆₄O₅₆, corresponding to copper(II) malonate trihydrate, is in fact the 2 : 1 co-crystal bis(diaquadimalonatocopper-tetraaquacopper)-[(diaquadimalonato-copper)-bis(tetraaquacopper)](2+) diaquadimalonatocuprate(2-), [(H₂O)₂Cu(O₂CCH₂CO₂)₂ · Cu(H₂O)₄]₂ · [(H₂O)₂Cu(O₂CCH₂CO₂)₂ · {Cu-(H₂O)₄}₂]2+ [(H₂O)₂Cu(O₂CCH₂CO₂)₂]2-. The compound crystallizes in the monoclinic P2₁/c space group, with a = 14.96(2), b = 14.97(2), c = 26.00(3) Å; β = 103.91(1) °; Z = 4, ρ_calc = 2.064 g cm-3.
