;The hydrogen-bond-directed inclusion properties of two related enanti
omerically pure diamide-type hosts have been investigated. The (11S,12
S)-trans-N, N'-dicyclohexyl-9, 10-dihydro-9, 10-ethanoanthracene-11, 1
2-dicarboxamide host, C30H36N2O2, (I), formed a quaternary compound wh
en crystallized from a dimethylformamide solution and also includes cy
clohexylamine and HCl as guests [(I).DMF.cyclohexylamine.HCl 1:1:1:1],
C30H36N2O2 . C6H14N+. C3H7NO . Cl-, (Ia). Three-component crystals we
re grown from a dimethyl sulphoxide solution of the 1S,12S)-trans-N,N'
-di-tert-butyl-9.10-dihydro-9,10 -ethanoanthracene-11, 12-dicarboxamid
e host, C26H32N2O2, (II), also containing H2O as a guest [(II).- DMSO
. H2O 1:2:1], C26H32N2O2 . C2H6OS . H2O, (IIb). Infinite supramolecula
r frameworks in both compounds are created involving host and guest mo
lecules in a way that not only host-guest, but guest-guest hydrogen-bo
nding interactions are observed. However, no direct host-host hydrogen
bonds were formed between the chiral diamide molecules (I) or (II).
