Metal complexes of a calix[4]arene diamide: Syntheses, crystal structures and molecular mechanics calculations on [Fe(L(1)-2H)][FeCl4] and [Er(L(1)-2H)(picrate)] (L(1)=5,11,17,23-tetra-tert-butyl-25,27-bis(diethylcarbamoylmethoxy)calix[4]arene)

Abstract:

Reactions of 5,11,17,23-tetra-tert-butyl-25,27-bis(diethylcarbamoylmethoxy)calix[4]arene (L1) with metal salts have been found to produce 1:1 metal/calixarene complexes. The rigid nature of the lower rim of the calix[4]arene in the cone conformation ensures that four donor oxygen atoms are approximately coplanar thus ruling out any possibility of orthogonal coordination and restricting the types of metals that form complexes. Complexes with Fe(III) and Er(III) are reported and structurally ch...
