Ionothermal Synthesis of Sulfidobismuth spiro-Dicubane Cations.

Bi S was dissolved in the presence of NaCl in the ionic liquid [BMIm]Cl ⋅ 4AlCl (BMIm=1-n-butyl-3-methylimidazolium) through annealing the mixture at 180 °C. Upon cooling to room temperature, orange, air-sensitive crystals of Na(Bi S )[S(AlCl ) ] [AlCl ] (1) precipitated. X-ray diffraction on single-crystals of 1 revealed a triclinic crystal structure that contains (Bi S ) spiro-dicubanes, [S(AlCl ) ] tetrahedra triples, isolated [AlCl ] tetrahedra, and sodium cations.

Metal Assisted Synthesis of Cationic Sulfidobismuth Cubanes in Ionic Liquids.

Bi S was dissolved in the presence of either AuCl/PtCl or AgCl in the ionic liquids [BMIm]Cl ⋅ xAlCl (BMIm=1-n-butyl-3-methylimidazolium; x=4-4.3) through annealing the mixtures at 180 or 200 °C. Upon cooling to room temperature, orange, air-sensitive crystals of [BMIm](Bi S )[AlCl ] (1) or Ag(Bi S )[S(AlCl ) ] [AlCl ] (2) precipitated, respectively.

Speciation of Copper(II)-Betaine Complexes as Starting Point for Electrochemical Copper Deposition from Ionic Liquids.

The application of ionic liquids for the dissolution of metal oxides is a promising field for the development of more energy- and resource-efficient metallurgical processes. Using such solutions for the production of valuable chemicals or electrochemical metal deposition requires a detailed understanding of the chemical system and the factors influencing it. In the present work, several compounds are reported that crystallize after the dissolution of copper(II) oxide in the ionic liquid [Hbet][NTf ].

Metal Assisted Synthesis of Cationic Sulfidobismuth Cubanes in Ionic Liquids.

Invited for this month's cover is the group of Michael Ruck at the Technische Universität Dresden (Germany). The cover picture shows the spiro-dicubane Bi S in the center, accompanied by two Bi S hetero-cubanes on both sides, which are shown along their threefold axis. These sulfidobismuth polycations were isolated in salts with [AlCl ] and [S(AlCl ) ] anions.

The Intermetalloid Cluster Cation (CuBi ).

The reaction of Bi, BiCl , and CuCl in the ionic liquid [BMIm]Cl⋅4 AlCl (BMIm=1-n-butyl-3-methylimidazolium) at 180 °C yielded air-sensitive shiny black crystals of (CuBi )[AlCl ] [Al Cl ] and (CuBi )[AlCl ] . For both compounds X-ray diffraction on single crystals revealed monoclinic structures that contain the intermetalloid cluster (CuBi ) . It is the first pure bismuth cluster with a 3d metal and the first with a metal that does not form binary intermetallics with bismuth under ambient pressure.
