Circular Dichroïsm

The X-ray structural analysis of the title compound shows that the s-cis conformation is favoured in the solid state. This conformation is consistent with circular dichroism studies in methanol solution.

The title compound crystallizes orthorhombically (space group C 2221) with a = 797.0, b = 870.3 and c = 2739.0 pm. The anions are zwitterions which are heavily involved in intra- and intermolecular NH •••O and OH•••O hydrogen bonding. The two types of sodium cations are coordinated by six oxygen atoms each of which belongs to either SO3 groups (Na 2) or water molecules and SO3 groups (Na1). A second type of water molecules is not coordinated to the cations. The SS bond length is 208.2 pm. Infrared and Raman spectra of the title compound are reported and tentatively assigned. The SS stretching vibration is observed at 409 cm-1.

The X-ray structural analysis of (E)-S-phenyl-S-(2-phenylethenyl)-N-(p- tolylsulfonyl ) sulfoximine and (E)-N-methyl-S-phenyl-S-(2-phenylethenyl) sulfoximine shows that the s- cis conformation, in which the C=C and S=O bonds are approximately syn coplanar, is favoured in the solid state.

Abstract Yellow crystals of cis-[SnCl4(S8 O)2] containing the homocyclic sulfur oxide S8O have been prepared from the com ponents in carbon disulfide at -35 °C. An X-ray structural analysis carried out at -105 °C showed the com pound to be monoclinic, space group P21/n with Z = 4 in a unit cell of dimensions a = 821.2(2) pm, b = 1331.9(4) pm , c = 2071.7(6) pm and β = 91.82(2)°. The structure was refined to a final agreement factor R = 0.038 for 2022 reflections. The tin atom is surrounded by a distorted octahedron of two oxygen atoms in cw-positions and four chlorine atoms in accordance with other oxygen-bonded complexes of SnCl4. The molecular symmetry is approximately C2, and the SS bond lengths in the ligands vary between 201 and 218 pm. Vibrational spectra of [SnCl4(S8O)2] are reported. The title compound is the second example containing S8O as a ligand.

A redetermination of the crystal and molecular structure of the chain-like molecule S(NSO)2 resulted in the following molecular parameters: d(SO) = 146.5(2), d(S = N) = 153.4(2), d(S-N) = 165.7(2) pm, bond angles OSN = 117.5(1)°, SNS = 123.6(2)°, and NSN = 97.2(1)°, torsion angles OSNS = -0.3(2)°, and SNSN = -177.7(2)° (molecular symmetry C2). Infrared and Raman spectra of S(NSO)2 are reported and assigned; there is no evidence for conformational changes on dissolution of crystalline S(NSO)2

Low Ionic Strength

While DNA-dependent RNA polymerase represents one of the key enzymes involved in transcription and ultimately in gene expression in procaryotic and eucaryotic cells, little progress has been made towards elucidation of its 3-D structure at the molecular level over the past few years. This is mainly because to date no 3-D crystals suitable for X-ray diffraction analysis have been obtained with this rather large (MW ~500 kd) multi-subunit (α2ββ'ζ). As an alternative, we have been trying to form ordered arrays of RNA polymerase from E. coli suitable for structural analysis in the electron microscope combined with image processing. Here we report about helical polymers induced from holoenzyme (α2ββ'ζ) at low ionic strength with 5-7 mM MnCl2 (see Fig. 1a). The presence of the ζ-subunit (MW 86 kd) is required to form these polymers, since the core enzyme (α2ββ') does fail to assemble into such structures under these conditions.
