Synthesis, structure and properties of hybrid supramolecular compounds based on macrocyclic H-bonding assemblies

Two novel hybrid Bi(III) supramolecular compounds based on guest cations and 18-crown-6, [(1,4-PMNH3)center dot(18-crown-6)](3)center dot 0.5(1,4-PMNH2).0.5(18-crown-6)center dot(Bi2Cl9)1 (1) and [(OH3)center dot(18-crown-6)](2)center dot 2(H3O)center dot 2(H2O).(Bi2Cl10)] (2), have been synthesized through controlling the reaction conditions, respectively, and characterized by single crystal X-ray diffraction, elemental analysis, IR, XRPD, UV, DSC, TGA, proton NMR and luminescence (1,4-PMNH2 = 1,4-phenylenedimethanamine). The rotator-stator assemblies, [(1,4-PMNH3)center dot(18-crown-6)(+) and ROH3)center dot(18-crown-6)(+), were formed by the guest cations inserting into crown ether macrocycle through strong N(O)-H center dot center dot center dot O H-bonding interactions. These ions and molecules were alternately stacked together to build the two different supramolecular compounds. (C) 2013 Elsevier B.V. All rights reserved.
