Ulli Englert |
Ulli has been leading the molecular structure group since 1989. He is interested in the synthesis of building blocks for extended structures, in engineering and reactivity of molecular crystals - for short: in all solid state aspects of molecular solids. Home lab equipment apart, neutron diffraction at FRM2 Munich and synchrotron radiation at DESY Hamburg and ESRF Grenoble provide the data! |
Irmgard Kalf |
Irmgard was trained as a laboratory technician. She worked on the synthesis, spectroscopic characterization, and crystal chemistry of coordination compounds. She is an expert in crystallization methods and a frequent co-author of our publications. |
Hans Gildenast |
As his first encounter with our ditopic ligands was really productive, Hans joined us for his Master thesis and successfully came up with a new sulfur-based ligand. His doctoral dissertation targeted hard-soft coordination by substituted phosphatriptycenes. Their restrained geometry implies modest sigma donor but excellent pi acceptor properties. Hans obtained his doctoral degree in Spring 2023- |
Steven van Terwingen |
After his successful Master thesis on extended ditopic ligands, Steven has been focussing on more rigid connectors between the hard and soft coordination sites, their derivatives and potential applications in catalysis. He and his bachelor students discovered the peaceful coexistence of orthogonal halogen and hydrogen bonds in hydrohalides. Steven graduated in autumn 2022. |
Ruimin Wang |
Ruimin received her BSc in 1984 from Nankai University, China and her Diploma with RWTH Aachen in 1995 with Prof. Welf Bronger. She was awarded her PhD in 2000 for a thesis on mixed crystals of Cobalt (III) complexes and lattice energy calculations in our group. After her graduation, she focussed on experimental electron density based on high resolution diffraction experiments. In 2019, Ruimin became a guest professor of Shanxi University, Taiyuan/China. |
Marius Kremer |
In the context of his M.Sc. thesis, Marius was investigating the degradation of one of our favourite ditopic ligands. His doctoral dissertation focused on Bio-MOFs; in parallel, he triggered our our regular stays at beamline P24 in DESY. Marius is now working for Anton Paar in non-ambient and in-situ powder diffraction. |

Qianqian did her undergraduate studies in Zhengzhou University, China and earned her MSc in the group of Prof. Hongwei Hou. She joined our group with a fellowship from the China Scholarship Council and obtained her PhD with studies on Pd chain polymers and their tunable phase transitions and on a new ditopic ligand. Qianqian also invented a very useful way to enforce O coordination in substituted acetylacetones. Qianqian now works at the International Office of Zhejiang University. |
Stefanie Langenstück |
Steffi was trained as a teacher in chemistry, biology and mathematics. In a joint venture with Prof. Michael Schroeder, IPC, she built a bridge between up-to-date research and didactics. Steffi was in charge of the Schüleruni Chemie. |
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 and is now a patent attorney. |
