| Abstract: | The reaction of [Cu2(O2CCH3)4·2H2O] with trimethoprim is reported. In methanol a green solution was obtained, which, on adding benzene, yielded tetrakis(μ-acetato)bis(trimethoprim)dicopper(II) di-benzene methanol solvate. The compound crystallizes with four molecules per cell in the monoclinic space group C2/c, with a = 24.109(5), b = 15.256(3), c = 16.532(3) Å, β = 116.89(2) for λ(Mo-Kα) = 0.71073 Å. The copper atoms are bridged by four acetate groups to form the binuclear molecule [Cu2-(O2CCH3)4(TMP)2]·2C6H6·CH3OH. The TMP ligand acts as a donor molecule through one pyrimidinic nitrogen atom. |
