Abstract:

Under the template of methyl viologen (MV2+ = methyl viologen) and ethyl viologen (EV2+ = ethyl viologen), two new viologen/iodobismuthate hybrids, (MV)5(Bi2I10)(Bi2I9)2 (1) and (EV)3(Bi4I18) (2) have been structurally determined. The highly interesting feature of 1 lies in its combination of two kinds of dimeric iodobismuthate clusters, i.e. (Bi2I10)4− and (Bi2I9)3− in one lattice induced by MV2+, which are constructed from edge- and face-sharing BiI6 octahedra respectively. But the (Bi4I18)6− tetramer in 2 is based on edge- and vertex-sharing BiI6 octahedra. C–H···I hydrogen bonds contribute to the formation of quasi-3-D networks. The smaller gap of 1 might be led by more versatile C–H···I hydrogen bond interactions due to the presence of mixed type iodobismuthate clusters. Two hybrids display reversible thermochromism behaviors. Theoretical calculation suggests that the terminal iodine is dominated in electron transfer of thermochromisms, rather than bridged iodine. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
