the mechanical constraints imposed by the ligating framework. Complexation with CuI and AgI with the reference unidentate carbene ligand Q, derived from the benzimidazolium precursor QH+, was studied for comparison. Both metals in MeCN form 1 : 1 and 1 : 2 complexes with the carbene ligand Q according to two stepwise equilibria. Q complexes of both metals are labile with respect to metal substitution

Two cluster-based metal–organic frameworks have been synthesized—one exhibits highly selective fluorescent detection of trace Hg2+ and the other shows antiferromagnetic interactions between Mn3+ ions.

Two new macrobicyclic imidazolium and benzimidazolium phanes were synthesized by direct quaternization of the corresponding tripodal azacycles with tribromide under high dilution condition in excellent yields. The cyclophanes were identified by H-1-NMR,C-13-NMR, FAB-MS, IR, elemental analysis and X-ray diffraction analysis.
