The two title ethoxycarbonylmethoxy derivatives of calix[4]-arene, namely diethyl 2,4-dihydroxycalix[4]arene-1,3-diyl-di(oxyacetate), C36H36O8, (I), and tetraethyl calix[4]arene-l,2,3,4-tetrayltetra(oxyacetate), C44H48O12, (II), form two different conformations, viz. a cone in (I), where intramolecular hydrogen bonds are formed through OH groups in a partially substituted calix[4]arene, and a 1,3-alternate form of a completely substituted calix[4]arene in (II). A unique three-dimensional array of molecules exists in (II), with the channels extended along the entire crystal.
