The synthesis and structural characterization of a lanthanum picrate complex of the proximally-substituted calix[4] arene bisamide, 5,11,17,23-tetra-tert-butyl-25,26-bis(diethylcarbamoylmethoxy)-27,28-dihydroxycalix[4]arene (L), is reported. The complex is formulated as [La(L-H)(picrate) 2]center dot 2.75CH(2)Cl(2) and crystallises with two inequivalent metal complexes in the unit cell. The differing dispositions of the picrate anions in the two complexes suggest that intramolecular interactions between the aromatic rings of the picrate and calixarene are less significant than the forces involved in the crystal packing of the complexes.
