The X-ray structure of the 1,4-butanediol clathrate ofN,N′-[1,3-azulenylenebis(methylene)]bis(trimethyl-ammonium)-diiodide is described, and the differences as well as the similarities to the 1-butanol inclusion of the same host are discussed in detail. The unit cell data of further clathrates of this new type are quoted.
