A Step in Between : [ Sn 3 Bi 3 ] 5 and Its Structural
نویسنده
چکیده
Extraction of “RbSnBi” in liquid ammonia yielded the cluster anion [Sn3Bi5] 3 , which could be crystallized in the compound [Rb@[2.2.2]crypt]3[Sn3Bi5]·8.87NH3. This anion is found to be derived from the formerly reported [Sn4Bi4] 4 by the formal substitution of one tin atom by bismuth. In contrast, the extraction of “RbSn2/Rb3Bi2” in liquid ammonia yielded the anion [Sn3Bi3] 5 in the compound Rb6[Sn3Bi3][Sn4]1/4·6.75NH3. The structural correlation of the two novel clusters indicates that [Sn3Bi3] 5 might be an intermediate of the reaction pathway to [Sn3Bi5] 3 and [Sn4Bi4] 4 . Each cluster is investigated by means of the electron localization function and further characterization was performed by using ESI-MS.

Sn-doped bismuth telluride nanowires with high conductivity.
Bismuth telluride (Bi(2)Te(3)) nanowires with sub-100 nm diameters were synthesized by Au-Sn co-catalyzed chemical vapor deposition. These Bi(2)Te(3) nanowires were single crystals with a hexagonal lattice. The Sn catalyst played a key role in achieving the one-dimensional nanowire structures, while the absence of Sn resulted in other morphologies such as nanoplates, nanooctahedrons and nanosph...
متن کاملOn Modified Borel Methods
for x>0. One says that 5-lim 5„ = 5|7?'-lim 5„ = 5] if lim^.,*, B(x; sk) = s[limx^x B'(x; sk)=s]. The relations between these Borel methods B, B', and their behavior under change of index are known [8, p. 183; 6; 7]. Following a suggestion of R. P. Boas, Jr., we intend to study in this paper the modified Borel methods which arise when the continuous variable x in (1.1) is replaced by the discre...
متن کاملWettability of amorphous and nanocrystalline Fe78B13Si9 substrates by molten Sn and Bi
The wettability of amorphous and annealing-induced nanocrystalline Fe78B13Si9 ribbons by molten Sn and Bi at 600 K was measured using an improved sessile drop method. The results demonstrate that the structural relaxation and crystallization in the amorphous substrates do not substantially change the wettability with molten Bi because of their invariable physical interaction, but remarkably det...
متن کاملIntermetallic Phase Formation and Thickness of Tin- Zinc Based Lead-free Solders
In this study the intermetallic (IMC) thickness of Sn-Pb, Sn-Zn and Sn-Zn-Bi solders on copper (Cu) substrate were measured at different temperatures using reflow methods. Cu6Sn5 intermetallic phase was detected between Sn-Pb solder and Cu substrate. The -Cu5Zn8 phase was detected between Sn-Zn and Sn-Zn-Bi lead-free solders with Cu substrate. The thickness of the intermetallics increases with ...
