Complex formation of muellitol with dipositive cations is fast, with tripositive cations slow, on the n.m.r . time-scale. The lanthanide- induced shifts of the signals in the 1H and 13C n.m.r . spectra of these complexes vary greatly, in sign and magnitude, with the nature of the solvent.

Magnetic Resonance Spectra

Complex formation between europium tris(dipivalatomethane), Eu(DPM)3, and cyclic amines is not accompanied by inversion of the amine configuration, even for 2-alkyl and 2,6-dialkylpiperidines, where inversion of the amine configuration accompanies formation of the usual amine derivatives. There is, however, a steric effect of C-2 or C-6 substitution, in that the magnitude of the lanthanide induced shifts is sharply reduced.

Coordination Ability

Intercalation and in situ formation of three fluorescent complexes, Al(III)-, Cr(III)- and Cu(II)-10-hydroxybenzo[h]quinolone (M-HBQ, M = Al, Cr and Cu), in the interlayer spaces of magadiite (mag) were studied by solid–solid reactions between metal ions exchanged mags (M-mag, M = Al, Cr and Cu) and HBQ. Results show that the basal spacings of the intercalated composites increase after the intercalation of HBQ into M-mags. The amount of HBQ in the intercalated compounds is different due to the amount of metal ions and the diversification of coordination ability of metal ions, and the order of the coordination ability of these three metal ions is Cu 2+  > Cr 3+  > Al 3+ . The amount of the metal cations in the interlayer of mag is enough for the in situ complex formation of M-HBQ complexes. The slight shift of the absorption and luminescence bands of the complexes suggests the different microstructures, including molecular packing of the complexes in the interlayer spaces of mags, resulting that the host–guest interactions are formed. These findings show that the intercalation and in situ formation of M-HBQ complexes (M = Al, Cr and Cu) in the interlayer space of mag are successfully achieved in the current work.
