Already in 2006 the working group of Häkkinen came to the conclusion that Au–S ring motifs are stable and that there is a possibility to find such structural motifs in metalloid gold clusters. 99 Two years later the working group of Jiang proposed that the staple motif is energetically preferred over the ring motif.
A metalloid is an element that possesses a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals, and which is therefore hard to classify as either a metal or a nonmetal. This is a generic definition that draws on metalloid attributes consistently cited in the literature. The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table. Metalloids have properties of both metals and non-metals. 2007-12-17 · In group IV, the upper elements, carbon can form a giant covalent structure with pure carbon.
