The reaction of the neutral dithiolene [Pd(Et2timdt)2] (Et2timdt = formally monoreduced diethylimidazolidine-2,4,5-trithione) with an excess of Br2 yielded few crystals of [1(Et) x 2Br](2+)(Br-)2(Br2)3 as a by-product (1(Et) = 4,5,9,10-tetrathiocino-[1,2-b:5,6-b']-1,3,6,8-tetraethyl-diimidazolyl-2,7-dithione); X-ray diffraction analysis showed that this compound represents the first example of ...

High bromine containing dimers of tetrabromoanthra- p -quinodimethane as appealing building-blocks for organic synthesis. Thorough study their isomerism and optoelectronic properties.
This paper from the Bulletin of the Bureau of Standards , Vol. 9, No. 1, 1913, pp. 131–150, is reprinted to commemorate the NIST Centennial on March 3, 2001. Ten papers have been selected from the Journal and its predecessors for this purpose, one from each decade of NIST’s existence. They appear in 10 of the 12 issues of the Journal published in 2000 and 2001, starting with the March–April 200...
Abstract Bromine is a key halogen element in the quantification of volcanic volatiles, but analytical difficulties measuring its very low abundances have prevented progress understanding behavior and role emissions. We present new data set bromine, chlorine, fluorine concentrations melt inclusions matrix glasses for two rhyolitic super-eruptions from Toledo Valles calderas, New Mexico, USA. sho...
