25,26,27,28-Tetra­butoxy-5,11,17,23-tetra-tert-butyl­calix[4]arene chloro­form tetra­solvate dihydrate

The title compound, C(60)H(88)O(4)·4CHCl(3)·2H(2)O, is the alkyl­ated product of 5,11,17,23-tetra-tert-butyl­calix[4]arene. It adopts a distorted cone conformation which leads to an open cavity. All the phenolic rings are tilted so that their tert-butyl groups are pitched away from the calix cavity....

Descripción
Sumario:The title compound, C(60)H(88)O(4)·4CHCl(3)·2H(2)O, is the alkyl­ated product of 5,11,17,23-tetra-tert-butyl­calix[4]arene. It adopts a distorted cone conformation which leads to an open cavity. All the phenolic rings are tilted so that their tert-butyl groups are pitched away from the calix cavity. Two opposite aromatic rings are close to being perpendicular to one another [dihedral angle 85.0 (2)°], while the other pair of opposite rings is almost parallel [dihedral angle 8.1 (2)°], and adjacent phenolic rings are almost perpendicular [dihedral angles 82.4 (1) or 87.9 (1)°]. In the crystal, the water molecule and calixarene interact by way of O—H⋯O hydrogen bonds.
