5,11,17,23-Tetra-tert-butyl-25,27-bis[2-(4-nitrophenoxy)ethoxy]calix[4]arene-26,28-diol acetonitrile tetrasolvate
In the crystal structure of the title compound, C(60)H(70)N(2)O(10)·4CH(3)CN, the calix[4]arene mol-ecule adopts an open-cone conformation with two intra-molecular O-H⋯O hydrogen bonds. The four benzene rings of the calix[4]arene are twisted to the mean plane defined by four methyl-ene C atoms bridging the benzene rings, with dihedral angles ranging from 57.74 (10) to 65.99 (12)°. Two pendant n...

In the title compound, C(48)H(64)O(4)·0.5CH(2)Cl(2), both crystallographically independent calixarene mol-ecules display a partial cone conformation. Their crystal packing is stabilized by C-H⋯π contacts involving the meth-oxy groups. The solvent mol-ecule is located inter-stitially between two calixarene units with C-H⋯Cl contacts to meth-oxy and tert-butyl groups. One tert-butyl residue of ea...

THE TITLE COMPOUND [SYSTEMATIC NAME: 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetra-propyn-yloxy-2,8,14,20-tetra-thia-calix[4]arene], C(52)H(56)O(4)S(4), is an alkyl-ated product bearing four propyne groups at the lower rim of a 5,11,17,23-tetra-tert-butyl-tetrathia-calix[4]arene. The mol-ecule is located on a crystallographic twofold rotation axis, running through two S atoms and perpendicular ...

The title thia-calix[4]arene derivative, C72H80O4S8, adopts a 1,3-alternate conformation, where the four 4-methyl-sul-fan-yl-benzyl groups are located alternately at the two sides of a virtual plane defined by the four bridging S atoms. In the crystal, there are no significant inter-molecular inter-actions present. Some of the peripheral tert-butyl and methyl-sulfanyl groups are disordered over...
متن کامل2-(4-Bromobenzyl)-5,11,17,23-tetra-tert-butyl-25,26,27,28-tetramethoxycalix[4]arene
In the title compound, C(55)H(69)BrO(4), the calixarene mol-ecule displays a 'partial cone' conformation bearing the lateral substituent in a sterically favorable equatorial arrangement between two syn-orientated arene units. The crystal packing is stabilized by weak C-H⋯π contacts, involving one tert-butyl group, and π-stacking inter-actions of the lateral bromo-benzene units [centroid-centroi...
