1,2:3,5-Bis[(4-tert-butyl-phen-yl)boranedi-yl]-?-d-glucofuran-ose.

ABSTRACT: The crystal structure of the title compound, C(26)H(34)B(2)O(6), comprises two crystallographically independent mol-ecules. In the crystal, the mol-ecules are linked by multiple inter-molecular O-H?O and C-H?O hydrogen bonds into a two-dimensional array.

5,15-Bis(3,5-di-tert-butyl-phen-yl)-10,20-bis-(phenyl-ethyn-yl)porphyrin.

Project description:In the centrosymmetric title compound, C(64)H(62)N(4), the two phenyl-ethynyl groups lie at diagonal meso positions. The 24-membered porphyrin has in-plane distortion with respect to the mean plane of the macrocycle and two intra-ring bifurcated N-H?(N,N) hydrogen bonds occur. The dihedral angles between the phenyl rings in the phenyl-ethynyl group and the 3,5-bis-(tert-but-yl)phenyl group with respect to the mean plane of the porphyrin are 17.2?(2) and 59.2?(3)°. The tert-butyl groups are disordered over two sets of sites in a 0.661?(13):0.339?(13) ratio.

Crystal structure of 1,2-bis-[(2-tert-butyl-phen-yl)imino]-ethane.

Project description:The whole molecule of the title compound, C22H28N2, (I), is generated by inversion symmetry. The mol-ecule is rather similar to that of 2,3-bis-[(2-tert-butyl-phen-yl)imino]-butane, (II), a di-imine ligand comprising similar structural features [Ferreira et al. (2006 ▶). Acta Cryst. E62, o4282-o4284]. Both ligands crystallize with the -N=C(R)-C(R)=N- group around an inversion centre, in a trans configuration. Comparing the two structures, it may be noted that the independent planar groups in both mol-ecules [the central link, -N=C(R)-C(R)=N-, and the terminal aromatic ring] subtend an angle of 69.6 (1)° in (II) and 49.4 (2)° in (I). Ferreira and co-workers proposed that such angle deviation may be ascribed to the presence of two non-classical intra-molecular hydrogen bonds and steric factors. In fact, in (I), similar non-classical hydrogen bonds are observed, and the larger angular deviation in (II) may be assigned to the presence of methyl groups in the di-imino fragment, which can cause steric hindrance due to the presence of bulky tert-butyl substituents in the aromatic rings. The C=N bond lengths are similar in both compounds and agree with comonly accepted values.

1,1'-Bis[bis-(4-tert-butyl-phen-yl)meth-yl]ferrocene.

Project description:The molecule of the title compound, [Fe(C26H31)2], is located on an inversion center. The two cyclopentadienyl rings exhibit a staggered conformation, which results from the bulky bis(4-tert-butylphenyl)methyl substituents situated on opposite sides of the molecule.

trans-1,2-Bis(3,5-dimethoxy-phen-yl)ethene.

Project description:The title compound, C(18)H(20)O(4), was prepared in high yield from 3,5-dimethoxy-styrene via a Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed. Inter-estingly, one symmetric unit contains two mol-ecules adopting an s-syn-anti and and an all-s-anti conformation.

2,4-Di-tert-butyl-6-[1-(3,5-di-tert-butyl-2-hydroxy-phen-yl)eth-yl]phenyl 4-methyl-benzene-sulfonate.

Project description:The title compound, C(37)H(52)O(4)S, was obtained by the reaction of 6,6'-(ethane-1,1-di-yl)bis-(2,4-di-tert-butyl-phenol) and 4-methyl-benzene-1-sulfonyl chloride. The mol-ecular conformation is stabilized by an intra-molecular O-H?O hydrogen bond. Two of the tert-butyl groups are disordered over two sets of sites with occupancies 0.530?(15)/0.470?(15) and 0.615?(11)/0.385?(11).

1,4-Bis[4-(tert-butyl-sulfan-yl)phen-yl]buta-1,3-diyne.

Project description:The asymmetric unit of the title compound, C(24)H(26)S(2), consits of one half-mol-ecule, which is located on a center of inversion. The two benzene rings are exactly coplanar while the tert-butyl group is oriented nearly perpendicular to the ring plane [C-S-C-C = -81.14 (11)°].

Crystal structure of trans-N,N'-bis-(3,5-di-tert-butyl-2-hy-droxy-phen-yl)oxamide methanol monosolvate.

Project description:The here crystallized oxamide was previously characterized as an unsolvated species [Jímenez-Pérez et al. (2000 ▸). J. Organomet. Chem. 614-615, 283-293], and is now reported with methanol as a solvent of crystallization, C30H44N2O4·CH3OH, in a different space group. The introduction of the solvent influences neither the mol-ecular symmetry of the oxamide, which remains centrosymmetric, nor the mol-ecular conformation. However, the unsolvated mol-ecule crystallized as an ordered system, while many parts of the solvated crystal are disordered. The hy-droxy group in the oxamide is disordered over two chemically equivalent positions, with occupancies 0.696 (4):0.304 (4); one tert-butyl group is disordered by rotation about the C-C bond, and was modelled with three sites for each methyl group, each one with occupancy 1/3. Finally, the methanol solvent, which lies on a twofold axis, is disordered by symmetry. The disorder affecting hy-droxy groups and the solvent of crystallization allows the formation of numerous supra-molecular motifs using four hydrogen bonds, with N-H and O-H groups as donors and the oxamide and methanol mol-ecule as acceptors.

Project description:The title compound, C14H6F4O2, crystallizes with half of a mol-ecule per asymmetric unit and exhibits bond lengths and angles typical of α-diketones. A network of C-H⋯F contacts and π-π stacking inter-actions is observed within the structure.

Diethyl 2,2-bis-(3,5-di-tert-butyl-4-hy-droxy-benz-yl)malonate.

Project description:The title mol-ecule, C(37)H(56)O(6), possesses twofold symmetry, with the twofold axis passing through the quaternary C atom. In the crystal, neighbouring mol-ecules are linked via O-H?O hydrogen bonds involving the phenol OH group and the carbonyl O atom, forming chains propagating in [101]. Within these chains, rings are formed with an R(2) (2)(20) motif. There are also C-H?O inter-actions present within the rings.
