Project description:In the title compound, C(56)H(44)Br(4)O(4), the calix[4]arene unit displays the 1,2-alternate conformation with crystallograpically imposed inversion symmetry. The four phen-oxy rings of the calix[4]arene unit are twisted about the mean plane defined by the four methyl-ene C atoms bridging the benzene rings, with dihedral angles of 46.73?(6) and 66.11?(5)°. The dihedral angle between adjacent phen-oxy rings is 74.75?(7)°. The two pendant bromo-phenyl rings on the same side of the calix[4]arene unit are nearly perpendicular to each other, with a dihedral angle of 72.85?(10)° due to an intra-molecular C-H?? inter-action. In the crystal, a Br?Br contact of 3.6350?(5)?Å, an inter-molecular C-H?Br hydrogen bond and an inter-molecular C-H?? inter-action are observed.

Bis[hexa-aquacobalt(II)] 25,26,27,28-tetra-hydr-oxy-2,8,14,19-tetra-thia-calix[4]arene-5,11,17,23-tetra-sulfonate monohydrate.

Project description:In the crystal structure of the title compound, [Co(H(2)O)(6)](2)(C(24)H(12)O(16)S(8))·H(2)O, the thia-calix[4]arenetetra-sulfonate (= TCAS(4-)) anions adopt a cone-type conformation with an additional water mol-ecule as a guest mol-ecule in the hydro-phobic cavity. The TCAS(4-) anions are arranged in layers in an up-down fashion. These anionic layers alternate with cationic layers consisting of rather regular octahedral cations (symmetry m). Several medium O-H?O hydrogen-bond inter-actions exist between the aqua ligands of the [Co(H(2)O)(6)](2+) cations and the O atoms of the sulfonate groups. In addition to the two crystallographically different Co atoms, two S and four O atoms are situated on mirror planes.

5,11,17,23-Tetra-tert-butyl-25,26,27,28-tetra-methoxy-calix[4]arene dichloro-methane hemisolvate.

Project description: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?? 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 each calixarene mol-ecule is disordered over two positions (occupancies 0.60/0.40 and 0.63/0.37), resulting in bond distances that deviate from ideal values. The tetra-mer calixarene mol-ecules present models with approximate non-crystallographic C(s) symmetry.

31-Benz-yloxy-5,11,17,23,29-penta-tert-butyl-calix[5]arene-32,33,34,35-tetra-ol.

Project description:The title compound, C62H76O5, known to be one of the most versatile synthetic precursors/inter-mediates of calix[5]arene derivatives, adopts an approximate Cs -symmetric cone-in conformation. The aryl-oxybenzyl ring is tilted in such a way that the p-tert-butyl group fills the macrocycle cavity, while the benzyl group moves away from the cavity axis. In the crystal, this conformational arrangement is secured by intra- and inter-molecular O-H?O hydrogen bonds forming inversion dimers. Four tert-butyl groups are disordered over two orientations, with occupancy ratios of 0.745?(6):0.255?(6), 0.837?(5):0.163?(5), 0.850?(5):0.150?(5) and 0.845?(8):0.155?(8).

Project description:Mol-ecules of the title compound, C(56)H(76)Cl(4)O(16)S(4), have crystallographic C(2) symmetry and adopt a 1,3-alternate conformation where the four -OCH(2)CH(2)OCH(2)CH(2)Cl groups are located alternately above and below the virtual plane (R) defined by the four bridging S atoms. The dihedral angles between the plane (R) and the phenolic rings are 72.85?(7) and 74.57?(7)°. An unusual 24-membered macrocyclic ring is formed in the crystal structure with an array of eight intra-molecular C-H?O hydrogen bonds between the ether arm H atoms and the sulfonyl O atoms. In the supra-molecular structure, the mol-ecular components are linked into infinite zigzag one-dimensional chains by a combination of four inter-molecular C-H?O hydrogen bonds, forming R(2) (2)(13), R(2) (2)(16), R(2) (2)(21) and R(2) (2)(26) ring motifs. These chains are augmented into a wave-like two-dimensional network by weak C?O inter-actions. One tert-butyl group shows rotational disorder, and one CH(2)CH(2)Cl group is disordered over two orientations; the site-occupation factors are 0.756?(6) and 0.244?(6) for the two tert-butyl groups, and 0.808?(3) and 0.192?(3) for the two CH(2)CH(2)Cl units.

Project description: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 two positions. A region of disordered electron density, occupying voids of ca 700?Å(3) for an electron count of 124, was treated using the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].

5,17-Dibromo-26,28-dihy-droxy-25,27-diprop-oxy-2,8,14,20-tetra-thia-calix[4]arene.

Project description:In the title compound, C(30)H(26)Br(2)O(4)S(4), the thia-calix[4]arene unit adopts a pinched cone conformation, with one of the ether-substituted rings bent towards the calix cavity and the two phenolic rings bent outwards. The phenyl rings make dihedral angles of 27.12?(9), 36.71?(10), 75.04?(8), and 76.01?(7)° with the virtual plane defined by the four bridging S atoms. The two opposite ether-substituted rings are almost parallel to each other, with an inter-planar anagle of 2.99?(12)°, while the two phenolic rings are nearly perpendicular to each other, making a dihedral angle of 74.52?(11)° and a Br?Br distance of 13.17?(2)?Å. Two intra-molecular O-H?O hydrogen bonds between the OH groups and the same ether O atom stabilize the cone conformation. In the crystal, two different chains of mol-ecules, one with alternating and the other with tail-to-tail orientations, are formed by inter-molecular offset-face-to-face ?-? stacking inter-actions with distances of 3.606?(3) to 4.488?(4)?Å between the centroids of the aromatic rings.
