Abstract:

The title compound [Cu(dafone)2(DMF)2] ·2ClO4 1 (dafone = 4,5-diazafluoren-9-one, dmf = N,N′-dimethyl formamide) was synthesized by the reaction of Cu(ClO 4)2 and dafone in DMF solution at room temperature with pH = 3.0. The single-crystal X-ray analysis has revealed that 1 crystallizes in monoclinic, space group P21/n with a = 8.4853(8), b = 13.1520 (14), c = 14.3866(12) Å, β = 102.629(3)°, V = 1566.7(3) Å3, C28H26Cl2CuN 6O12, Mr = 773.00, Z = 2, Dc = 1.639 g/cm3, F(000) = 790, μ = 0.942 mm-1, the final R = 0.0438 and wR = 0.1214 for 3165 observed reflections with I > 2σ(I). X-ray analysis shows that compound 1 has unsymmetric chelation of dafone with one Cu-N bond being much longer than the other. Coordination geometry of Cu is a highly distorted octahedron and the whole structure is stabilized by π-π stacking and static attractive forces from [ClO4]- anions. Based on the crystal data, quantum chemistry calculation at the DFT/ B3LPY level was used to reveal the electronic structure of 1.
