Crystal structure of ({4-[(4-bromo-phen-yl)ethyn-yl]-3,5-di-ethyl-phen-yl}ethyn-yl)triiso-propyl-silane.

ABSTRACT: The title compound, C29H37BrSi, was synthesized by the Sonogashira coupling of [(3,5-diethyl-4-ethynylphen-yl)ethyn-yl]triiso-propyl-silane with 4-bromo-1-iodo-benzene. In the structure, the two phenyl rings are nearly parallel to each other with a dihedral angle of 4.27?(4)°. In the crystal, ?-? inter-actions between the terminal and central phenyl rings of adjacent mol-ecules link them in the a-axis direction [perpendicular distance = 3.5135?(14); centroid-centroid distance = 3.7393?(11)?Å]. In addition, there are weak C-H?? inter-actions between the isopropyl H atoms and the phenyl rings of adjacent mol-ecules.

Crystal structure of [2-(tri-ethyl-ammonio)-eth-yl][(2,4,6-triiso-propyl-phen-yl)sulfon-yl]amide tetra-hydrate.

Project description:The zwitterionic title compound, C23H42N2O2S·4H2O, crystallized as a tetrahydrate from a solution of N-[(2,4,6-triiso-propyl-phen-yl)sulfon-yl]aziridine in tri-ethyl-amine, diethyl ether and pentane in the presence of moist air. It is formed by a nucleophillic ring-opening that is assumed to be reversible. The mol-ecular structure shows a major disorder of the triiso-propyl-phenyl group over two equally occupied locations. An inter-esting feature is the uncommon hydrate structure, exhibiting a tape-like motif which can be classified as a transition of the one-dimensional T4(2)6(2) motif into the two-dimensional L4(6)5(7)6(8) motif.

Crystal structure of 1-[(2,4,6-triiso-propyl-phen-yl)sulfon-yl]aziridine.

Project description:The title compound, C17H27NO2S, exhibits a distorted geometry of the aromatic ring with elongated bonds at the ipso-C atom. The S atom deviates from the aromatic ring plane by 0.393 (4) Å. Similar to this, the adjacent isopropyl groups are bent out of the aromatic ring plane by -0.125 (4) and -0.154 (4) Å. Even the distant isopropyl group in para-position to the sulfonyl moiety shows a slight deviation from the ring plane of 0.111 (5) Å. These distortions, which are caused by the bulky substituents, can also be observed in related sulfonyl-aziridine structures.

Project description:The synthesis and crystal structures of two tris-(tri-alkyl-sil-yl)silyl bromide compounds, C9H27BrSi4 (I, HypSiBr) and C27H63BrSi4 (II, TipSiBr), are described. Compound I was prepared in 85% yield by free-radical bromination of 1,1,1,3,3,3-hexa-methyl-2-(tri-methyl-sil-yl)tris-ilane using bromo-butane and 2,2'-azobis(2-methyl-propio-nitrile) as a radical initiator at 333 K. The mol-ecule possesses threefold rotational symmetry, with the central Si atom and the Br atom being located on the threefold rotation axis. The Si-Br bond distance is 2.2990 (12) Å and the Si-Si bond lengths are 2.3477 (8) Å. The Br-Si-Si bond angles are 104.83 (3)° and the Si-Si-Si bond angles are 113.69 (2)°, reflecting the steric hindrance inherent in the three tri-methyl-silyl groups attached to the central Si atom. Compound II was prepared in 55% yield by free-radical bromination of 1,1,1,3,3,3-hexa-isopropyl-2-(triiso-propyl-sil-yl)tris-ilane using N-bromo-succinimide and 2,2'-azobis(2-methyl-propio-nitrile) as a radical initiator at 353 K. Here the Si-Br bond length is 2.3185 (7) Å and the Si-Si bond lengths range from 2.443 (1) to 2.4628 (9) Å. The Br-Si-Si bond angles range from 98.44 (3) to 103.77 (3)°, indicating steric hindrance between the three triiso-propyl-silyl groups.

Project description:In the title salt, C14H13Br3NOS2 (+)·Br(-), synthesized by bromination of mesoionic 2-[2-(piperidin-1-yl)-1,3-di-thiol-2-ylium-4-yl]phenolate in glacial acetic acid, the dihedral angle between the 1,3-di-thiol-ium ring and the phenolic substituent ring is 45.9 (3)° due to the steric influence of the ortho-Br group on the 1,3-di-thiol-ium ring. The piperidine ring adopts a chair conformation. In the crystal, the cation and anion are linked by an O-H⋯Br hydrogen bond.

The mol-ecules of all the three compounds are U-shaped with the two aromatic rings inclined at 41.3 (6)° in (I), 42.1 (2)° in (II) and 54.4 (3)° in (III). The mol-ecular conformation of (II) is stabilized by intra-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions. The crystal structure of (I) features N-H⋯O hydrogen-bonded R22(8) loops inter-connected via C(7) chains of C-H⋯O inter-actions, forming a three-dimensional architecture. The structure also features π-π inter-actions [Cg⋯Cg = 3.6970 (14) Å]. In (II), N-H⋯O hydrogen-bonded R22(8) loops are inter-connected via π-π inter-actions [inter-centroid distance = 3.606 (3) Å] to form a one-dimensional architecture running parallel to the a axis. In (III), adjacent C(4) chains of N-H⋯O hydrogen-bonded mol-ecules running parallel to [010] are connected via C-H⋯π inter-actions, forming sheets parallel to the ab plane. Neighbouring sheets are linked via offset π-π inter-actions [inter-centroid distance = 3.8303 (16) Å] to form a three-dimensional architecture.
