The molecule of the title compound, C 64 H 96 O 4 , adopts the typical pinched-cone conformation. The dihedral angles between the reference plane (defined by the C atoms of the methylene bridges) and the benzene rings are 86.88 (4), 136.64 (5), 87.22 (4) and 133.99 (4) .
The title compound, C 64 H 66 O 6 P 2 , possesses crystallographic twofold symmetry and displays the calixarene cone conformation. The two symmetry-independent calixarene rings subtend interplanar angles of 143.06 (3) and 97.71 (4) to the reference plane of the bridging C atoms. The phosphoryl O ato
