Abstract
- The reactions of mono-, bis- and tetrapicolyl-p-tert-butylcalix[4]arene derivatives functionalised in the phenolic positions (L1-L4) with copper(II) acetate resulted in the formation of discrete complexes or extended coordination polymers. The centrosymmetric dimer [Cu2(μ-O2CCH3)4(L1)2] 1, obtained with monodentate L1, has square pyramidal coordination around the copper centres and a cone conformer of monopicolyl-calix[4]arene acting as an axial ligand, with a molecule of acetonitrile hosted within its cavity. The potentially bidentate L2 acts as a monodentate ligand, affording the complex [Cu2(μ-O2CCH3)4(L2)2] 2, which based on spectroscopic and combustion analysis data has a similar coordination sphere around Cu(II). Compound L3 bridges two dicopper units in the coordination polymer [Cu2(μ-O2CCH3)4(μ-L3)]n 3, with the calixarene hosting a molecule of tetrahydrofuran. Finally, compound L4 reacts with 4 equivalents of copper(II) acetate, presumably generating a two-dimensional coordination polymer formulated as [{Cu2(μ-O2CCH3)4}2(L4)] 4. [ABSTRACT FROM AUTHOR]
