Partial cone conformer of 25,27-bis­[(methoxy­carbonyl)­meth­oxy]-26,28-dipropoxycalix[4]arene

Mol­ecules of the title compound, C(40)H(44)O(8), adopt a partial cone conformation. The dihedral angles between the planes of the aromatic rings and the mean plane through the methyl­ene C atoms bridging the aromatic rings are 35.74 (7), 85.86 (5), 87.77 (4) and 89.95 (5)°. Two opposite aryl rings...

description Mol­ecules of the title compound, C(40)H(44)O(8), adopt a partial cone conformation. The dihedral angles between the planes of the aromatic rings and the mean plane through the methyl­ene C atoms bridging the aromatic rings are 35.74 (7), 85.86 (5), 87.77 (4) and 89.95 (5)°. Two opposite aryl rings are approximately parallel to each other; the others are at an inter­planar angle of 52.41 (6)°. Intra- and inter­molecular C—H⋯O hydrogen bonds stabilize the mol­ecular conformation and the crystal packing. Two C atoms of one propoxy chain are disordered over two positions; the site occupancy factors are ca 0.66 and 0.34.
