ABSTRACT: The tellurium atom in the title bis-ethynyl telluride, Te(C(9)H(7))(2) or C(18)H(14)Te, is located on a crystallographic twofold axis, the C-Te-C angle being 92.23?(15)°. The dihedral angle between the rings is 87.27?(7)°. In the crystal structure, mol-ecules are connected in chains parallel to the b axis and mediated by C-H?? inter-actions.

Project description:In the title bis-tolane derivative, C(29)H(24)O(2), the central benzene ring forms dihedral angles of 29.12?(9) and 26.46?(9)° with the other two benzene rings. The dihedral angle between two terminal benzene rings is 55.58?(8)°.

1,4-Bis[(2,6-dimethoxy-phen-yl)ethyn-yl]benzene.

Project description:The title compound, C(26)H(22)O(4), is a derivative of 1,4-bis-(phenyl-ethyn-yl)benzene substituted by four meth-oxy groups at the terminal benzene rings. The asymmetric unit consists of two half-molecules; one centrosymmetric molecule is planar but the other is non-planar, with dihedral angles of 67.7 (1)° between the central benzene ring and the terminal benzene rings. In the crystal structure, mol-ecules form a zigzag mol-ecular network due to π-π [the inter-planar and centroid-centroid distances between the benzene rings are 3.50 (1) and 3.57 (1) Å, respectively] and C-H⋯π inter-actions (2.75 Å). Introduction of the four meth-oxy groups results in the supra-molecular architecture.

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.

Project description:The asymmetric unit of the title compound, C(26)H(16)F(6)O(2), contains one half of the mol-ecule situated on an inversion centre. In the rod-like mol-ecule, the two terminal benzene rings form a dihedral angle of 71.9 (1)° with the central benzene ring. The trifluoro-methyl group is rotationally disordered over two orientations in a 0.53 (1):0.47 (1) ratio. The crystal packing exhibits no classical inter-molecular inter-actions.

1,4-Bis[(3,5-dimethoxy-phen-yl)ethyn-yl]benzene.

Project description:The title compound, C(26)H(22)O(4), is a derivative of 1,4-bis-(phenyl-ethyn-yl)benzene substituted by four meth-oxy groups on the terminal benzene rings. The mol-ecule is almost planar with an r.m.s. deviation of 0.266?Å. The dihedral angles between the two terminal benzene rings and the central benzene ring are 7.96?(6) and 13.32?(7)°. In the crystal structure, mol-ecules aggregate via C-H?O inter-actions, forming mol-ecular tapes along the a axis, which aggregate to form a herring-bone structure.

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

Project description: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.
