Trimeth-yl(triphenyl-meth-oxy)silane.

ABSTRACT: In the title mol-ecule, C(22)H(24)OSi, the Si-O-C angle is 139.79?(11)°, the O-C-C angles of the triphenyl-meth-oxy group are in the range 106.13?(13)-109.22?(14)° and the O-Si-C angles of the trimethyl-sil-yloxy group are in the range 103.08?(10)-113.53?(10)°. In the crystal, face-to-face ?-? interactions are observed between the phenyl rings [centroid separation = 4.194?(1)?Å, interplanar spacing = 3.474?Å and centroid shift = 2.35?Å]. The three phenyl groups of the triphenyl-methyl substituent are mutually nearly perpendicular, with dihedral angles in the range 80.49?(8)-81.53?(8)°. There are only weak inter-molecular van der Waals inter-actions in the crystal.

1-Methyl-2-[(E)-2,4,5-trimeth-oxy-styr-yl]pyridinium 4-meth-oxy-benzene-sulfonate monohydrate.

Project description:In the title compound, C(17)H(20)NO(3) (+)·C(7)H(7)O(4)S(-)·H(2)O, the cation exists in an E configuration with respect to the C=C bond and is twisted with a dihedral angle of 17.81?(8)° between the pyridinium and benzene rings. The benzene ring of the anion is almost parallel to the pyridinium ring [dihedral angle = 3.45?(9)°], whereas it is inclined to the benzene ring of the cation [dihedral angle = 17.62?(8)°]. The crystal structure is stabilized by O-H?O hydrogen bonds and weak C-H?O inter-actions which link the cations, anions and water mol-ecules into chains along the a axis. ?-? inter-actions with centroid-centroid distances of 3.7751?(9) and 3.7920?(11)?Å are also observed.

Project description:There are three independent mol-ecules in the asymmetric unit of the title compound, C12H15Br3O3, two of which have approximate trigonal symmetry, the third being conformationally different as it adopts near mirror symmetry.

3-{3,5-Bis[(2-but-oxy-eth-oxy)carbon-yl]-2,6-dimethyl-1,4-dihydro-pyridin-4-yl}-1-[(3,4,5-trimeth-oxy-benzo-yl)meth-yl]pyridinium bromide.

Project description:In the title salt, C37H51N2O10(+)·Br(-), the 1,4-dihydro-pyridine (1,4-DHP) ring adopts a slighly puckered boat conformation. The N and opposite C atoms deviate from the least-squares plane calculated through the four other ring atoms by 0.068?(5) and 0.224?(5)?Å, respectively. The orientation of both C=O groups is similar (cis with respect to the double bonds of 1,4-DHP. The pyridinium ring has an axial orientation with respect to the1,4-DHP ring and is almost perpendicular to the least-squares plane of the 1,4-DHP ring, making a dihedral angle of 89.2?(3)°. The mol-ecule has a compact shape due to the parallel orientation of the long-chain substituents. One of the but-oxy groups was fond to be disordered (occupancy ratio 0.70:0.30). In the crystal, the bromide anion accepts a weak hydrogen bond from the N-H group of a neighboring 1,4-DHP ring.

Project description:In the asymmetric unit of the title compound, C(18)H(20)N(2)O(5), there are two crystallographic independent mol-ecules.

In the crystal, mol-ecules are linked by N-H?O hydrogen bonds and weak C-H?O inter-actions into tapes along the b axis. C-H?? inter-actions are also present.
