2 ], (2), were prepared by reaction of Hg(SePh) 2 , HgX 2 (X = Cl, Br) and tricyclohexylphosphine, PCy 3 , in dimethylformamide. The reaction of Hg(TePh) 2 with HgBr 2 in tetrahydrofuran using triphenylphosphine or 2,2'-bipyridine as co-ligands gave the polymeric cluster [{Hg 5 Br 3 (TePh) 7 } n ] (3), whose dissolution in dimethylsulfoxide yielded the cluster [Hg 3 Br 3 (TePh) 3 ]•2dmso. The influence of different ligands, coordinating solvents and reaction stoichiometries on the formation of the title compounds is also discussed. All complexes were characterized by elemental analysis, thermogravimetric analysis and single crystal X-ray diffractometry.

Neste artigo estamos apresentando a síntese do composto [Cd 8 Cl 2 (µ 4 -Se) (SePh) 12 (PCy 3 ) 2 ]·2.5CH 3 OH pela reação de Cd(SePh) 2 com CdCl 2 e triciclohexilfosfina em metanol em um reator de aço inoxidável sob condições solvotérmicas a 130 °C. Esse composto corresponde ao último resultado de uma série sistemática de reações e visando ao crescimento de clusters moleculares a partir de Cd(SePh) 2 como reagente de partida. A importância desta síntese não está baseada somente nas propriedades do produto preparado, mas também no seu possível uso, por exemplo, no desenvolvimento de novas metodologias via estratégias "bottom up" para a obtenção de clusters a partir de uma mesma classe de reagentes -M(ER) 2 (M = metal, E = calcogênio, R = alquil ou aril). O composto apresentado neste artigo foi caracterizado por difração de raios X em monocristal, análise elementar, análise termogravimétrica e espectroscopia no UV-Vis. Estes últimos resultados foram correlacionados com dados calculados por DFT, teoria do funcional de densidade.In this article we present the synthesis of the compound [Cd 8 Cl 2 Se(SePh) 12 (PCy 3 ) 2 ]·2.5CH 3 OH by the reaction of Cd(SePh) 2 with CdCl 2 and PCy 3 in methanol in a stainless steel sealed reactor under solvothermal conditions at 130 °C. This compound represents the latest result of our systematic work on the growth of molecular clusters from Cd(SePh) 2 as starting material. Their importance is based not only on the properties of the new compounds, but also by their possible use, for example, in the development of new methods via a ''bottom up" strategy to obtain different clusters from single components like M(ER) 2 (M = metal, E = chalcogen, R = alkyl or aryl). The title compound was characterized by single crystal X-ray diffractometry, elemental analysis, thermogravimetrical analysis and the UV-Vis spectroscopy. These results were correlated with data calculated by DFT, density functional theory. Keywords: cadmium(II) complexes, selenium, tellurium, clusters IntroductionOrganylchalcogen groups bound to metal atoms to generate nanoclusters have become increasingly important due to their potential as semiconductors, among other materials and biological applications. [1][2][3][4] The unique optical and electronic properties inherent to these "quantumconfined particles" (quantum-dots) have been attributed to modifications of the electronic structure -depending upon the particle size -which lead to very different structures than those found in molecular solids or bulk materials. [5][6][7] Our search for new metalchalcogen-containing building blocks is of great interest for many reasons, principally because the variable size of the blocks produces tunable optoeletronic properties of the bulk products, [8][9][10] This emerging field -super lattices of crystalline chalcogenideslinks two traditional, but distinct, areas of research: chalcogenide clusters and reticular materials. [11][12][13][14][15][16][17][18][19] Some authors have proposed alternative ways for the development of metal-...

Keywords: Copper / Sulfur / Selenium / Tellurium / ClustersThe investigation of coinage metal molecular clusters bridged by chalcogen atoms represents an area of ever increasing activity in recent chemical and material science research. This is largely due to the relatively high ionic and even higher electric conductivity of binary coinage metal chalcogenides, which leads to properties intermediate between those of semiconducting and metallic phases. In addition, the size-dependency of the chemical, physical, and structural properties of substances on going from small molecules to bulk materials is of general interest. Approaches towards the synthesis and investigation of such clusters have included the study of colloidal nanoparticles with a narrow size distribution, as well as the formation and isolation of [a] ϩ49 (0)7247/82-6368 Andreas Eichhöfer (left) was born in Hünfeld, Germany, in 1964. He received his diploma in 1991, and subsequently graduated in 1993 in the group of Prof. D. Fenske at the university of Karlsruhe with a doctoral degree on metal-phosphorous cluster complexes. He then moved to the group of Prof. G. Fritz at the same institute to work on carbosilanes as precursor compounds for the fabrication of SiC fibers. After that he returned to his previous group and became a research scientist at the Institute of Nanotechnology at the Forschungszentrum Karlsruhe in 1999, where he is currently investigating the syntheses and properties of semiconductor cluster compounds. Stefanie Dehnen (center) was born in Gelnhausen, Germany, in 1969. She obtained her diploma from the University of Karlsruhe in 1993 and her doctoral degree in 1996 under the supervision of Prof. D. Fenske on experimental and theoretical investigations of copper sulfide and copper selenide clusters. After a postdoctoral stay with Prof. R. Ahlrichs (1997) she returned to the inorganic chemistry department at the University of Karlsruhe where she is presently preparing her Habilitation. In 1997, she was awarded a Feodor-Lynen-Stipendium of the Alexander-von-Humboldt-Stiftung, and in 1998, she received a Margarete-von-Wrangell-Habilitations-Stipendium of the state of Baden-Württemberg. Her current research interests comprise the synthesis, structural elucidation and chemical reactivity of binary or ternary polyanions of main group elements. Dieter Fenske (right) was born in Dortmund, Germany, in 1942. He studied chemistry at the University of Münster where he also received his doctoral degree in 1973 with Prof. H. J. Becher.
