First Time

For the first time, during the investigation of the Ag submonolayer on the Ge(111) system, large, independent domains of the Ge (111)-(3×1) Ag phase were imaged and investigated. Previous studies have reported it only as small insets between Ge (111)-(4×4) Ag and Ge (111)- c (2×8) domains. The transmission electron diffraction data were analyzed using a Direct Methods approach and "heavy-atom holography," with the result of an atomic model of the structure similar to that of Ge (111)-(3×1) Ag .

The title compound has been prepared in two different ways: First, by boiling single crystals of [(C2H5)4N]HgCl3 in a mixture of n-hexane/n-octane [4:1] at T = 350 K, and second, in a synthesis from stoichiometric quantities of the components. X-ray structure analysis gave the stoichiometry [(C2H5)4N]2Hg3Cl8, monoclinic, space group P21, a = 7.538(3), b = 19.909(6), c = 10.274(3) Å, β = 95.13(1)°, V = 1535.7(9) A3, Z = 2. The basic [Hg3Cl8]2--units form broken zig-zag chains along [100]. The Hg–Cl distances within the [Hg3Cl8]2- clusters range from 2.315(3) to 2.755(4) Å. This is a new coordination type for halomercurates.

Thin, broad crystals of DNA can be grown by slow precipitation in ethanolic aqueous solution (1,2). Crystals of this form are well suited to study by electron diffraction and electron microscopy. In preliminary experiments to test the feasibility of applying electron crystal 1ographic techniques to obtain a direct structure determination of the DNA in these crystals, we have obtained electron diffraction patterns from the crystals. These patterns are the first diffraction patterns of any kind to be obtained from single crystals of highly polymerized DNA.
