Abstract The reactions of N-alkyl-N′-picolyl-benzimidazolium bromides or N,N′-dipicolyl-benzimidazolium bromide with silver oxide yielded the silver dicarbene complexes of the type [Ag(NHC)2][AgBr2] 1–4 (NHC = picoline-functionalized benzimidazolin-2-ylidene). The silver complexes 1–4 have been used in carbene transfer reactions to yield the gold(I) complexes of the type [AuCl(NHC)] 5–8 in good yields. A halide exchange at the metal center of complexes 5–8 with lithium bromide yielded the gold bromide complexes 9–12. Finally, the oxidation of the gold(I) centers in complexes 9–12 with elemental bromine gave the gold(III) complexes of the type [AuBr3(NHC)] 13–16. Molecular structures of selected Au(I) and Au(III) complexes have been determined by X-ray diffraction studies.

A new species of Haploglenius Burmeister, 1839 from Colombia (H. abdominevittatus Ardila & Jones sp. nov.) is described.This species is unique among members of Haploglenius—which are newly diagnosed here under a slightly revised definitionby the presence of three rows of anal cells in the hind wing—in having both a well-developed axillary angle and a highly exca-vated posterior margin at the base of the forewing, characters normally distinctive of other Neotropical genera of Haploglenii-nae. This species also exhibits unique color patterning on the abdomen. The male genitalia are illustrated, a first for species in the genus.

More than 20 binary tungsten iodides have been discovered. This was possible due to a new synthesis of W3I12 through halide exchange reaction and by thermal scanning. Depending on the I2 partial pressure compounds can incorporate or release I2. On heating they undergo self-reduction. Some tungsten iodide clusters can be directly transferred into solution.

Specific attributes were recorded for 119 textiles recovered from burial contexts from Craig Mound at the Spiro site and eight southern Ozark bluff shelters. Textile attributes that varied according to status designations of the burial contexts were identified using the following three avenues of investigation. The textiles were rated using an ordinal index of production complexity, and more complex textiles were found to be associated with burial contexts of presumed higher status. Use of a series of contingency tables identified edge finishes, color, patterning, design motif, fiber, and scale as attributes that are individually associated with status differences. When selected attributes were considered together using a classification and pattern-recognition program, color description, scale, fiber, and number of yarn components were identified as the best predictors of status association.
