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.

5,11,17,23-Tetra-kis(chloro-meth-yl)-25,26,27,28-tetra-propoxycalix[4]arene.

Project description:The title calix[4]arene, C(44)H(52)Cl(4)O(4), displays the 1,3-alternate conformation with crystallographically imposed twofold symmetry. Four phenolic rings of the calixarene backbone are tilted into the calix cavity, making dihedral angles of 77.42 (2) and 77.71 (2)° with the plane of the four bridging methyl-ene C atoms. Pairs of opposite aromatic rings make dihedral angles of 25.16 (3) and 24.58 (4)° with each other. In the crystal, the calixarene mol-ecules pack with the formation of infinite columns along the b axis. The crystal packing shows a network of C-H⋯Cl contacts, which can be considered as non-classical hydrogen bonds.

5,17-Dibromo-26,28-bis-[(meth-oxy-carbon-yl)meth-oxy]-25,27-diprop-oxy-2,8,14,20-tetra-thia-calix[4]arene.

Project description:The title thia-calix[4]arene derivative, C(36)H(34)Br(2)O(8)S(4), adopts an unusual pinched cone conformation with the prop-oxy-substituted benzene rings inclined inward [forming a dihedral angle of 33.4 (1)°] and with the brominated benzene rings bent outward, making a dihedral angle of 66.1 (1)°. In the crystal, the mol-ecules form chains along [001] via C-H⋯S hydrogen bonds and S⋯S contacts [S⋯S = 3.492 (3) Å]. The chains are associated into bilayers through C-H⋯O hydrogen bonds, generating an R(2) (2)(10) motif.

7,11,15,28-Tetra-kis[(2-formyl-phen-oxy)methyl]-1,21,23,25-tetra-methyl-resorcin[4]arene cavitand ethyl acetate clathrate at 173 K.

Project description:The title compound, C(68)H(56)O(16), was synthesized as a novel synthetic inter-mediate towards deeper and more elaborate resorcin[4]arene cavitands. The structure is the first reported example of a resorcin[4]arene cavitand bearing aromatic aldehyde functional groups at the extra-annular rim of the mol-ecule. The 2-formyl-phen-oxy residues are found to assume two different orientations above the mol-ecular cavity. One half of the resorcin[4]arene cavitand mol-ecule appears in the asymmetric unit; the complete resorcin[4]arene cavitand structure was generated across a mirror plane. In addition, a highly disordered ethyl acetate solvent mol-ecule is present within the mol-ecular cavity.

7,11,15,28-Tetra-methyl-1,21,23,25-tetra-kis(2-phenyl-ethyl)resorcin[4]arene ethyl acetate clathrate.

Project description:The title compound, C(68)H(64)O(8)·C(4)H(8)O(2), is a new resorcin-[4]arene cavitand synthetic precursor, obtained by alkyl-ation of a previously reported resorcin[4]arene. The additional alkyl bridges significantly rigidify the structure and enforce a 'bowl' shape on the mol-ecular cavity. In the crystal structure, the mol-ecule lies on a crystallographic mirror plane, and a single ethyl acetate mol-ecule (also lying on the mirror plane) is present within the compound cavity, illustrating the host capabilities of the mol-ecule.

[5,10,15,20-Tetra-kis(4-meth-oxy-phen-yl)porphyrinato]zinc di-chloro-methane disolvate.

Project description:In the title compound, [Zn(C48H36N4O4)]·2CH2Cl2, the Zn(II) ion lies on an inversion center and is coordinated in an almost ideal square-planar geometry. The asymmetric unit also contains one di-chloro-methane solvent mol-ecule. The unique meth-oxy-substituted benzene rings form dihedral angles of 59.38?(6) and 66.77?(6)° with the mean plane (r.m.s. deviation of fitted atoms = 0.0282?Å) of the atoms in the porphyrin core. The packing is characterized by close contacts between the Zn(II) ion and two symmetry-related mol-ecules through the O atoms of a meth-oxy-phenyl group [Zn?O = 2.694?(2)?Å], forming a two-dimensional network parallel to (100).

1,3-Alternate conformer 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetra-kis-(4-methyl-sulfanylbenz-yloxy)-2,8,14,20-tetra-thia-calix[4]arene.

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.
