First- and second-sphere co-ordination of a lanthanum cation by a calix[4]arene tetraamide in the partial-cone conformation
5,1 l,17,23-Tetra-/er/-butyl-25,26,27,28-tetrakis(diethylcarbamoylmethoxy)calix[4] arene (L) has been synthesized in the partial-cone conformation for the first time. Reaction with lanthanum picrate (2,4,6-trinitrophenolate) gives a 1:1 complex which has been structurally characterised: [LaL(pic)3(H...
