Abstract:
Two new organic/bismuth(III) iodide hybrids have been synthesized by a solution process, and their crystal structures were determined by an x-ray diffraction method. The first one, (EMP)(3)(Bi2I9) (EMP+ = N-ethyl-4-methyl-pyridinium) (1), crystallizes in the monoclinic system, space group P21/c, with Mr = 3838.20, a = 19.945(4), b = 12.636(3), c = 20.327(4) angstrom, beta = 118.82(3)degrees, V = 4488.4(16) angstrom(3), Z = 2, D-c = 2.840 g/cm(3), F(000) = 3358, mu(MoK alpha) = 14.039 mm(-1), the final R = 0.0678, and wR = 0.1676 for 7272 observed reflections with I > 2 sigma(I). The second, [(Phendione)BiI4]center dot(Phendione-H)center dot C2H5OH (Phendione = 1,10-phenathroline-5,6-dione) (2), belongs to the monoclinic system, space group C2/c, with M-r = 1183.02, a = 37.254(8), b = 8.1776(16), c = 22.318(5) angstrom, beta = 111.38(3)degrees, V = 6331(2) angstrom(3), Z = 8, D-c = 2.842 g/cm(3), F(000) = 4296, mu(MoK alpha) = 9.511 mm(-1), the final R = 0.0526, and wR = 0.1050 for 6555 observed reflections with I > 2 sigma(I). Compound 1 contains halobismuthate dimers, and it is noteworthy that the dimers and its organic countercations connect with each other by C-H center dot center dot center dot I hydrogen bonds to form a layered structure. Compound 2 is composed of [(Phendione) BiI4](-) anions and Phendione-H+ cations, and hydrogen bonds contribute to give a one-dimensional (1-D) chain. The optical absorption spectra of 1 and 2 reveal the appearance of sharp optical gaps of 2.17 and 1.93 eV, respectively.
