Abstract

Metal complexes of divalent copper (1-2), cobalt (3), and nickel (4) with mixed ligands acetylacetone (acac) and adenine were prepared and characterized by IR, mass spectra, elemental and thermal analysis. The X-ray crystal structures of {[Cu(acac)₂(adenine)]•EtOH} complex (1) and {[Cu(acac)₂(adenine)]•DMF•H₂O} (2) were determined. Compound (1) crystallizes in the triclinic space group P - 1 with a = 7.547(3) Å, b = 7.828(3) Å, c = 17.791(6) Å, α = 79.538(6)°, β = 82.240(7)°, γ = 86.010(6)°, V = 1023.1(6) Å³, and Z = 2. Complex (1) forms a hydrogen bonded 2:2 complex {[Cu(acac)₂(adenine)]₂:[EtOH]₂} arranged in bilayers. Complex (2) crystallizes in the triclinic space group P - 1 with a = 7.828(2) Å, b = 8.095(2) Å, c = 16.995(5) Å, α = 78.508(5)°, β = 84.949(5)°, γ = 89.285(5)°, V = 1051.2(5) Å³, and Z = 2. Complex (2) also forms bilayers with H-bonded DMF. Thermal analysis TG and DSC of the compounds (25-800 °C, under N ₂) reveals the disproportionation of ligands with the associated heat.
