For (CH3CH2CH2CH2NH3) 6 (BiI6) (I) 2I3 1 = it crystallizes in triclinic = space group P1 with Mr = 2049.76 = a = 8.5719 1 = b = 11.7461 3 = c = 15.700 = V = 1451.4 3 = Z = 1 = Dc = 2.345 g / cm3 = F (000) = 924 = μ (MoKα) = 8.907 mm -1 = T = 293 (2) K = the final R = 0.0655 and wR = 0.0804 for 2399 observed reflections with I> 2σ (I) .For (NH3CH2CH2NH3) 2Bi2I10 2 = crystallizes in monoclinic = space group P21 / n with Mr = 1811.20 = a = 8.434 4 = b = 13.862 6 = c = 13.362 = V = 1499.9 123 = Z = 2 = Dc = 4.010 g / cm3 = F (000) = 1536 = μ (MoKα) = 22.007 mm -1 = T = 293 K = the final R = 0.0584 and wR = 0.1451 for 1798 observed reflections with I> 2σ (I ). The structures of 1 and 2 contain halobismuthate monomer and dimers = respectively. It is noteworthy that the dimers and their organic counters in 2 connect each other by N ··· I hydrogen bonds to form a layered structure = and the electrostatic i nteractions and crystal packing forces between layers give rise to the packing of the crystal. The optical absorption spectra of 1 and 2 reveal the appearance of sharp optical gaps of 2.13 and 2.01 eV = respectively.
