The structure of the title compound has been determined by X-ray analysis. It is monoclinic:a = 10.147,b = 10.081,c = 38.627 Å, ß = 102.27 °,Z = 4,P21/c. The structure was solved by standard methods and refined by least squares to a (conventional)R-factor of 4.7%. The Ru atom is in square-pyramidal configuration: the Ru-S distances (2.286, 2.336Å) are significantly different, but the Ru-P distances average to 2.389 Å. Comparisons are made with the violet isomer.

The crystal structures of RuS2, OsS2, RuTe2, and OsTe2were refined isotropically by least squares from powder diffractometer data using individual temperature factors. The resulting positional parameters of the chalcogen atoms in these C2-type structures are 0.3879 ± 14, 0.3865 ± 19, 0.3739 ± 9, and 0.3725 ± 18 respectively (for meaning of the uncertainty limits see Table II and text). The structure of Ir3Te8was refined from Hockings and White's published data to give x(Te) = 0.3702 ± 18. The shortest metal–chalcogen distances in these structures are Ru—S 2.351 ± 3 Å, Os—S 2.352 d ± 5 Å, Ru–Te 2.647 ± 3 Å, Os–Te 2.647 ± b 3 Å, and Ir—Te 2.651 ± 4 Å (not corrected for thermal motion). The shortest S–S distances (in the S2groups) are 2.179 ± 30 Å in RuS2and 2.210 ± 46 Å in OsS2. The corresponding shortest Te—Te distances are 2.791 ± fc 35 Å in RuTe2, 2.826 ± 38 Å in OsTe2, and 2.872 ± 30 Å in Ir3Te8(not corrected for thermal motion). Within the stated uncertainty limits the shortest metal–chalcogen distances are independent of the nature of the metal. The shortest chalcogen–chalcogen distances are so sensitive to variations in xthat even the above relatively narrow uncertainty limits preclude meaningful statements to be made about the effect of the metal on these distances, with the possible marginal exception of the nonstoichiometric C2 structure Ir3Te8.

The article offers an outlook for the stock market as of October 1956. Topics discussed include the importance of stock selection to the market's success, the impact of divergence within the market on the price level and the considerations overlooked by those who argue that the tight money situation is a deflationary force. Also mentioned is the premise that the business boom will slow up and turn downward after the mid-1957.

The article focuses on Southern Pacific's (SP) petroleum pipeline located along the right of way in Yuma, Arizona. It discusses how the company's broader view of things has made it the U.S. eigth biggest corporation. It provides SP executive Donald Joseph Russell's view of progress which describes as offering industrial customers whatever service that is fastest and most economical.

Focuses on the American participation in the Communist-sponsored Youth Festival in Moscow, Russia. Impact of the politically unsophisticated American youth on the city; Position of the Department of State on the attendance of American delegation in the event; Special treatment given by the Russian crowds and officials to the dark-skinned and the Arab delegates.

In this article, the author discusses his interaction with Soviet intellectuals. The Soviets have started to publish a literary review devoted to translations from foreign languages; and I met several times with members of their editorial boards. These people all know English. Some of them are translators; others poets; novelists and some critics and scholars. They asked for names of young writers in the various literary genres, wrote them down, asked which works in particular I thought ought to be translated, and which of them would interest a Russian public.

Presents letters to the editor referencing articles and topics discussed in previous issues. Comments on the Head Start school improvement program in Mississippi; Support for the candidacy of presidential candidate Hubert Humphrey; Economic assistance given by the U.S. to Latin America.

The general objective of this language is to facilitate both the modeling and experimental aspects of simulation studies. The ability to represent systems containing highly interactive processes is an essential feature. The nature of the language, and the role of the process concept, is presented by means of an extended example. [ABSTRACT FROM AUTHOR]

The article offers business news briefs from the U.S. as of July 15, 1936. Topics discussed include the Advertising Federation of America's convention, which featured truth-in-advertising movement, and efforts against misleading advertising and selling claims; a campaign to be launched by chemical company du Pont to promote the use of hard bound books as selling tools; and economic growth of the town of Rodessa in Louisiana, following the discovery of oil well in 1935.

The article offers information on the investments for the modernization of its facilities by automobile company Buick Motor Co. Topics discussed include the coordination of engineering and design changes with plant changes, the low costs of production due to modernization, and the use of conveyor-type machines in the modernization.

The article discusses technology advances in 1929 that are revolutionizing construction methods comparable to mass production in manufacturing that allow building projects in the U.S. to be finished ahead of schedule at reduced cost. It cites a Detroit, Michigan construction company that made records with the application of mass production methods in building motor car factories. It talks about new devices, mass production of mixed materials and swift hoisting that reduced hand labor and cost.
