At. Gubaidullin et al., X-ray analysis of the structure of an assembly of cationic aminomethylatedcalix[4]resorcinarene and the zinc tetrachloride anion, MENDELEEV C, (1), 1999, pp. 9-10
The first X-ray crystallographic data on an ionic host-guest self-assemblin
g system with water-soluble tetraprotonated macrocyclic 2,4,14,20-tetrameth
yl-5,11,17,23-(N,N-dimethylamino)methylenecalix[4]resorcinarene as a host a
nd zinc tetrachloride as a guest are presented.
