Redetermination of the room-temperature crystal structures of mononuclear chloro- and bromo-pyridinebis ( triphenylphosphine )silver(I) (previously described in space group P21/m) and di-μ-iodo-bis [(pyridine)( triphenylphosphine )silver(I)](previously described in space group C2/m), consequent upon the availability of crystals of improved quality, has permitted the reassignment of space groups as P21/a (with doubled a axis) and C2/c respectively, by virtue of the facilitated detection of weak superlattice reflections. Crystals of [ Cl,BrAg ( py )(PPh3)2] are monoclinic, P21/a, a ≈ 19.6, b ≈ 20.0, c ≈ 9.1Ǻ, β ≈ 97.5°, Z = 4; the structures were refined to residuals of 0.034 and 0.040 for 2965 and 2315 'observed' reflections respectively. [(PPh3)( py )AgI2Ag( py )(PPh3)] is monoclinic, C2/c, a 27.145(6), b 14.548(3), c 11.316(4)Ǻ, β 94.83(2)°, Z 4, refining to R 0.035 for 1892 'observed' reflections, and isomorphous with the [(PPh3)( py )CuX2Cu( py )(PPh3)] family. In spite of this reassignment, the previous descriptions of the AgX /N/P cores of the species are essentially unchanged, the previous residuals of the misassigned space group determinations being comparable with the present; the only non- trivial change lies in the fact that the disordered phenyl rings of the earlier work are now fully ordered. It now seems certain that the 'second polymorph' of [(PPh3)( py )CuBr2Cu( py )(PPh3)], recorded as being isomorphous with its C2/m silver iodide counterpart, is spurious and a consequence of the use of an inferior specimen.

Logarithmic Growth

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

Electrical And Magnetic Properties

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.
