Abstract:
A new 3-D hybrid framework {[(dafone)PbI2](dafbne)2}(n) 1 (dafone = 4,5-diazafluoren-9-one) has been prepared and structurally determined. 1 crystallizes in the monoclinic system, space group C2/c with a = 24.109(8), b = 16.596(8), c = 7.983(3) angstrom, beta = 91.590(15)degrees, V = 3193(2) angstrom(3), Z = 4, C33H18I2N6O3Pb, M-r = 1007.53, D-c = 2.096 g/cm(3), F(000) = 1880, mu(MoK alpha) = 7.262 mm(-1), the final R = 0.0352 and wR = 0.0951 for 3198 observed reflections with I > 2 sigma(I). In the [(dafone)PbI2](n) chain, the Pb center adopts a distorted octahedral coordination geometry and shares an edge to give a one-dimensional polymer. The 3-D arrangement of 1 constructs from H-bonds among dafone molecules and pi-pi stacking interactions among dissociative dafone molecules. These weak interactions contribute to the stability of the title compound. DFT calculation was carried out to reveal its electronic structure.
