Active Group Members:


Ulli Englert 

Ulli has been leading the molecular structure group since 1989. He is interested in analysis, engineering and reactivity of molecular crystals - for short: in all solid state aspects of molecular solids. This spells many more ideas for future coworkers and research students...

Irmgard Kalf

Born April 12, 1963 in Aachen. Irmgard was trained as a laboratory technician. She is now working on the synthesis, spectroscopic characterization, and crystal chemistry of coordination compounds. She is in charge of our crystallization lab.

Ruimin Wang

Ruimin received her BSc in 1984 from Nankai University, China and her Diploma with RWTH Aachen in 1995. She was awarded her PhD in 2000 for a thesis on mixed crystals of Cobalt (III) complexes and lattice energy calculations. Crystal modeling and charge density work apart, she keeps our good old LINUX computers alive... In 2019, Ruimin became a guest professor of Shanxi University, Taiyuan/China.

Steven van Terwingen

After his successful Master thesis on extended ditopic ligands, Steven is now focussing on more rigid connectors between the hard and soft coordination sites, their derivatives and potential applications in catalysis.

Mihaela Serb

Mihaela ("Mura") obtained her MSc from University 'Politehnica' of Bucharest. She was awarded a DAAD Fellowship for finishing her PhD in Aachen where she was assembling molecular building blocks to extended structures. Mura has successfully "petrified" one of the shortest O-H...O hydrogen bonds ever studied! Mura has recently been promoted to the rank of Associate Professor.

Magaret Kondracka

Magaret obtained her M.Sc. in Poland. Her PhD thesis in Halle was on molybdenum and tungsten chemistry. She has been successfully involved in the synthesis and structural characterization of mixed-metal coordination polymers. Margret is now working for INS Pulawy, Poland.

Desiree van Holt

Desy joined the group for her diploma thesis on molecular alloys. She obtained her doctoral degree with experimental work done in FZ Juelich.

Beatrice Cula

Beatrice ("Betty") obtained her MSc from University 'Politehnica' of Bucharest. Based on a fellowship of the graduate program 'Methods in Asymmetric Synthesis', she earned her PhD degree in our group in summer 2004 on chiral solids. After a Postdoctoral stay in Spain, she returned to Aachen where she worked in the field of novel organometallic platinum complexes with potential antitumor activity. In 2010, Betty joined Prof Christian Limberg's group at Humboldt University, Berlin, as a crystallographer. In 2021, she was elected vice-chairperson of the molecular crystallographers in DGK,

Yutian Wang

Yutian graduated from Shanxi University, China, and joined us in May 2005 as a PhD candidate. His work centered around chiral coordination polymers, particularly silver derivatives. Yutian received his PhD in May 2009. He is now working for the Chinese branch of Bruker as an application scientist.

Nadine Boymans

Nadine has been awarded a MINT scholarship for her PhD which was in the field of chemical didactics. She was in charge of our lab courses for grammar school students and the organizer for the summer university in chemistry. After her very successful graduation, Nadine started to work as a grammar school teacher.

Fangfang Pan

Fangfang obtained his MSc from Zhengzhou University and joined our group for the PhD with a fellowship from the China Scholarship Council. Fangfang worked on crystal engineering and charge density of dynamic coordination complexes and sulfonamides.He finished his doctoral dissertation in July 2013 and joined Kari Rissanen in Jyväskylä university for a post doc. At present, Fangfang is group leader in Central China Normal University, Wuhan.

Carina Merkens

Carina obtained her BSc with a thesis on thermolysis of organic-inorganic hybride materials. This strategy allows to prepare polymers which are not accesibble via conventional synthesis in solution. In her MSc and PhD project, she worked on the synthesis and structure of bimetallic networks. She was awarded the Friedrich-Wilhelm-Preis in 2012. Several of Carina's results will be published in the near future, so somehow she is still an "active group member"!

Friedrich Steuber

Friedrich did his B.Sc. and M.Sc. theses in our group, both on bimetallic coordination polymers and both with very good success. He is now working for his PhD in Ireland!

Kevin Lamberts

In his BSc thesis, Kevin studied a reversible crystal-to-crystal phase transition which is tunable over a wide temperature range by doping with an isomorphous compound. He was involved in an interdisciplinary seed fund project with graph theory experts (Prof. Guo & his team) and the virtual reality group (Prof. Kuhlen and coworkers) aiming at the simplification and understanding of extended structures. Kevin earned his doctoral degree with the coordination of amino acids of essential metals.

William Raven

William's PhD thesis focussed on the synthesis and structural characterization of cycloplatinated primary amines. He has addressed Pt(II) and Pt(IV) complexes, with the emphasis on potential applications in chemotherapy.
