摘要：
A series of crown ether based iodidobismuthates was prepared from dibenzo-18-crown-6 (DB18C6), BiI3 and NaI or KI in acetonitrile (MeCN). The resulting compounds [(DB18C6)Na(MeCN)(2)](4)[Bi6I22]center dot 2MeCN (1), [(DB18C6)Na(MeCN)(2)](4)[Bi8I28]center dot 6MeCN (2), [(DB18C6)Na(MeCN)(2)](2)[Bi6I20]center dot 3MeCN (3) and [(DB18C6)-K-(MeCN)](4)[Bi6I22]center dot 2MeCN (4) have been used to explore the templating effect of different crown ether based cations and the influence of the I/Bi ratio and I center dot center dot center dot I interactions on the optical properties of iodido-bismuthates. Compound 3 contains the strand-like anion (1)(infinity)[Bi6I20](2-), which displays a I/Bi ratio of 3.33, closer to the binary BiI3 than any other iodidobismuthate.
