Abstract:
A new bismuth(III) iodide inorganic/organic hybrid containing larger heterocyclic conjugated organic ligand, [(dppz)(2)Bi2I6]center dot 2DMF (1) (dppz = dipyrido[3,2-a:2',3'-c]phenazine), has been synthesized by solution process and structurally determined by X-ray diffraction method. 1 crystallizes in triclinic, space group P (1) over bar with M-r = 1844.08, a = 9.215(5), b = 11.488(6), c = 12.424(9) angstrom, alpha = 106.66(2)degrees, beta = 90.84(2)degrees, gamma = 92.34(2)degrees, V = 1258.5(13) angstrom(3), Z = 1, D-c = 2.433 g/cm(3), F(000) = 830, mu(MoK alpha) = 10.702 mm(-1), the final R = 0.0834 and wR = 0.1947 for 2749 observed reflections with I > 2 sigma(I). 1 consists of a dimeric structure [(dPPz)(2)Bi2I6], in which two [(dppz)BiI3] fragments are bridged by a pair of iodine atoms. Hydrogen bonds and pi center dot center dot center dot pi stacking interactions contribute to the structural extension and stabilization. Experimental band gap of about 2.13 eV indicates its semiconductor nature. The optical absorption spectrum and electronic structure were also discussed.
