Beschreibung der Forschungsaktivitäten
Im Zentrum der Forschungsinteressen des Arbeitskreises von Prof. Martin Köckerling stehen metallreiche Verbindungen früher Übergangsmetalle. Die experimentellen Arbeiten sind auf die Synthese, Strukturaufklärung und die Ermittlung physikalischer Eigenschaften neuartiger Substanzen sowie auf eine Weiterentwicklung des Verständnisses vom Zusammenhang der Eigenschaften und Strukturen dieser Verbindungen fokussiert. Hierzu werden Methoden der klassischen Festkörperchemie, der lösungsmittelchemisch orientierten molekularen Komplexchemie sowie theoretische Methoden der modernen Quantenmechanik eingesetzt. Ausgehend von und in engem Zusammenhang mit den auf metallreiche Verbindungen ausgerichteten Forschungsschwerpunkten wurde in jüngster Zeit mit Untersuchungen 1) neuartiger Metall-Tetracyanoborate und 2) („magnetischer“) ionischer Flüssigkeiten begonnen.

Bruker KAPPA APEX II
	X-ray diffractometer combining the high versatility of the 4-circle kappa goniometer with the very sensitive and fast CCD detector APEX II for microstructure analysis of single crystals. The instrument is equipped with the 700 series Oxford Cryostream unit, which allows fast cooling to 100 K by a cold stream of nitrogen gas. information: Unit cell determination Measurement of complete sets of diffraction intensities for structure solutions and refinements. Face indexing reactive sputtering under Argon or Oxygen atmosphere Image Analysis including zoom and panning, 3-D views, line graphs, rocking curves, resolution rings … Reciprocal lattice viewer Structure solution and refinement Pseudo Precession photograph Phase ID plugin

Glove box 1 + 2
Glove box 1 for water- and oxygen-free working including micro scaled weighting machine used to handle sensitive materials. This glove box allows to handle material solutions with all solvents but water.	Glove box 2 for anhydrous, solvent-f and oxygen-free working. It has a balance with a range down to milligrams and a microscope for selection of single crystals for X-ray diffraction
