Abstract:
The title compound [Cu(dafone)(2)(DMF)(2)]-2ClO(4) 1 (dafone = 4,5-diazafluoren-9-one, dmf = N,N'-dimethyl formamide) was synthesized by the reaction Of Cu(ClO4)(2) and dafone in DMF solution at room temperature with pH = 3.0. The single-crystal X-ray analysis has revealed that I crystallizes in monoclinic, space group P2(1)/n with a = 8.4853(8), b = 13.1520 (14), c 14.3866(12) angstrom, beta =102.629(3)degrees, V = 1566.7(3) angstrom(3), C28H26Cl2CuN6O12, M-r = 773.00, Z = 2, D-c = 1.639 g/cm(3), F(000) = 790, mu = 0.942 mm(-1), the final R = 0.0438 and wR = 0.1214 for 3165 observed reflections with I > 2 sigma(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 pi-pi 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.
