Thanks for visiting the Nippe Group website! We are an inorganic research group at Texas A&M with interests in the areas of molecular electrocatalysis and molecular magnetism. Our research explores various inorganic approaches to contribute to the development of novel systems for molecular solar energy conversion, small molecule activation, and molecules for information storage. We study fundamental aspects of reactivity and electronic structure aiming at identifying critical design elements of molecular architectures that will lead to new discoveries and systematic performance improvements. Synthetic methods build the foundation of the group, which are complimented by a broad array of spectroscopic and electrochemical techniques.

We are seeking students who are interested in creative inorganic synthesis, structure-function relationships in catalysis, and electronic structure of heterometallic d-block/f-block complexes.


Activation and energy-efficient conversion of small molecules such as CO2 and N2 remains a challenging area of global importance. Development of efficient electrocatalytic systems for CO2 reduction will establish artificial photosynthetic systems. Our research targets systematic design and synthesis of transition metal based electrocatalytic systems to investigate: secondary coordination sphere effects on electrocatalysis; intramolecular interactions between imidazolium and CO2 through functionalized Lehn-type catalysts; and modified reaction pathways to further understand catalytic cycles.

Molecular Magnetism

Single-molecule magnets (SMMs) offer the unique possibility for molecular scale, high-density data storage using the switchable orientation of their molecular spin. Lanthanides, in particular, have a lot of potential due to their unquenched orbital momentum. By optimizing the ligand field, we can increase the magnetic barrier and improve magnetic properties. We are also interested in multifunctional molecules that can alter their physical or chemical properties predictively in the presence of an outside trigger. This includes the use of reversible electron transfer to alter magnetization dynamics in lanthanide complexes.

Heterometallic Interactions

We are working on elucidating the effects of heterometallic interactions on static and dynamic magnetic properties as well as spectroscopic features of lanthanide ions. The fundamental scientific understanding of these interactions has been explored in complexes containing the first reported lanthanide-transition metal bonds. Understanding the consequences of these bonding and electronic interactions on the dynamic magnetic properties of various lanthanide ions will guide the development of new molecules for future data processing and storage.

Actinide Chemistry

We are in the process setting up a radioactive elements lab! Called AggieRad, this facility has two new gloveboxes for inert-atmosphere actinide chemistry as well as a multitude of characterization techniques specifically desgined for radioactive elements.
