Synthesis and Crystal Structure of a Ternary Lattice Inclusion System of C‐4‐acetamidophenylcalix[4]‐2‐methylresorcinarene dimethylsulfoxide tetrasolvate dihydrate

Abstract

C-4-acetamidophenylcalix[4]-2-methylresorcinarene. The calix molecule is associated with four dimethylsulfoxide (DMSO) and two water molecules of crystallization that contribute to the stability of the solid via hydrogen bonding. The supramolecule adopts a chair (C 2h ) conformation with four phenyl linkage groups that are in rctt (cis-trans-trans) configuration isomer. The thermal gravimetric investigation showed three mass loss steps that occurred at about 100, 400, and 900 C, respectively. The compound formed after the first loss is thermally stable in the range of 100-400 C after which the calix moiety began to decompose.
