Abstract: | Preparation and crystal structure of the novel compound [Bi3I(C4H8O3H2)2(C4H8O3H)5]2Bi8I30 are reported. The title compound is prepared by heating of BiI3 and diethylene glycol at 413 K in a sealed quartz glass tube filled with argon. Deep red single crystals are grown and applied to perform X-ray powder diffraction and X-ray single-crystal diffraction measurements. The compound crystallizes triclinic with space group P-1: Z=2, a=13.217(1) Å, b=15.277(1) Å, c=22.498(1) Å, α=84.33(1), β=73.18(1), γ=67.48(1). [Bi3I(C4H8O3H2)2(C4H8O3H)5]2Bi8I30 comprises the novel polynuclear [Bi8I30]6− anion and [Bi3I(C4H8O3H2)2(C4H8O3H)5]3+ as the cation. Cation as well as the anion can be assumed to represent intermediates between solid BiI3 and BiI3 completely dissolved in diethylene glycol. |
