Figure 1. Stereoscopic drawings of the molecular configuration of Mo2 r C H )2 CO)4t 2-H) g2-P CH )2) showing (a) thermal ellipsoids of nuclear motion for all atoms scaled to enclosed 50% probability (b) the atom labeling. The entire molecule possesses a pseudotwofold axis passing through the bridging hydrogen and phosphorus atoms.

Figure 6. Stereoscopic drawing of the [Cr2(CO) o(p2-H)] monoanion as viewed approximately along the Cr-Cr axis. The Cr-H-Cr plane is staggered with respect to the eclipsed array of equatorial carbonuls. The thermal anisotropy of the bridging hydrogen atom is primarily directed normal of the Cr-H-Cr plane.

Figure 5-14 (A) Stereoscopic drawing showing two layers of water molecules that form a "spine" or "ribbon" of hydration in the minor groove of B-DNA. The inner layer is shown as larger filled circles water molecules of the outer layer are depicted with smaller dots and are numbered. Hydrogen bonds are shown as dashed lines. (B) Electron density map. (A) and (B) from Tereshko et at.95 (C) Stereoscopic representation of the superimposed electron densities of 101 water molecules observed to hydrate 14 guanine rings found in 14 B-DNA molecules for which high-resolution X-ray structures were available. Positions of 101 water molecules within 0.34 nm from any atom of the 42 guanines are plotted. From Schneider and Berman.94...

Figure 5-23 Stereoscopic drawing showing a molecule of daunomycin (Fig. 5-22) intercalated between two base pairs in a molecule of double-helical DNA, d(CGTACG). Nitrogen and oxygen atoms are shown as dots. From Quigley et al.220 Both daunomycin and adriamycin (doxorubicin 14-hydroxy-daunomycin) are important but seriously toxic anticancer drugs.

Figure 5-35 Stereoscopic drawings illustrating the binding of a dimeric molecule of the Trp repressor protein to a palindromic sequence in DNA. (A) Schematic view showing structures of the aporepressor (partly shaded gray) and the holorepressor with bound tryptophan (unshaded) are superimposed. Cylinders represent the a helices in (B). From Zhang et al.wi (B) MolScript ribbon diagram with a few side chains that interact with the DNA shown. Two tandemly bound dimeric repressor molecules are shown. Two bound molecules of tryptophan are visible in each dimer. The DNA is drawn as a double helix with lines representing the base pairs. From Lawson and Carey.405...

Figure 23-29 (A) Stereoscopic drawing of light-harvesting complex from the dinoflagellate protozoan Amphidinium carterae. The central cavity contains eight molecules of peridinin, two of which can be seen protruding from the top. Deeply buried toward the bottom are two molecules of Chi a. Also present are two molecules of digalactosyl diacylglycerol. From Hofmann et al.268 Courtesy of Wolfram Welte. (B) Structure of peridinin.

Figure 3. Stereoscopic drawing of mixer and left and right mixer-settler building blocks material used is plexiglass. In the lower right drawing three scales are shown, each having 1 cm between tick marks.

Figure 4. Settler interface measuring device. The upper part of the figure is a stereoscopic drawing of the level transducer. Note that one electrode is covered with PTFE insulation, except for the lower tip. Electrode materials have been graphite or titanium. Lower part of the figure shows the level measuring circuit.

In the crystalline triphenylphosphine derivative 35> both iron atoms are on the same side of the plane defined by the allenic carbons. The stereoscopic drawing of the complex reproduced in the communication is particularly revealing of geometrical character 35>. Unfortunately, no evidence could be obtained regarding the angle between an HCH plane and the CCC plane they certainly need not be identical 56>. One hopes that similar complexes of tetramethylallene will soon be synthesized and structurally clarified.
