This activity was designed to assess student comprehension of how changes in pi-donation from ligands can affect both crystal field splitting and metal spin states. The activity requires students to practice electron counting, idealized crystal field splitting, and then apply these concepts to explain the observed change from low to high spin caused by the loss of a proton.
The MoleCVUE website contains several items that should be of interest to the VIPEr community, especially the activities. Each activity is designed to be ready to deploy in lecture, laboratory, or as homework. There are activities covering all of the major subdisciplines of chemistry (some more than others). Some activities that might be of particular interest to VIPEr are "Group Theory", "VSEPR", and "Electron Configurations of Atoms and Ions". All of the activities are written to use WebMO, but could be adapted for other systems. Most activities are doable with the free or demo versi
This is a literature-based end of semester project. After a semester of introducing literature in the form of typical literature discussions, this assignment is given to small groups. It may be easily amended or added to. Each group is provided with a paper and accompanying questions that are similar to the literature discussions they have done over the semester. They then must use these guiding questions to assemble a presentation to the class. The topics chosen and the guiding questions are designed to provide students with a taste of the many areas of inorganic chemistry that are no
This activity has students make observations on a series of metal complexes with varying geometries and electronic structures (tetrahedral vs octahedral, d7 vs d0). They are then led to develop hypotheses to explain the differences in their spectra based on crystal field theory and their understanding of selection rules. Finally, students inspect theoretical calculations to determine whether their hypotheses based on observation are supported by theory.
This article focuses on a theoretical analysis of K-edge X-ray Absorption Near Edge Structure (XANES) of Fe(CO)5 in the D3h and C4v geometries. For the context of a one semester inorganic chemistry / physical inorganic chemistry course, the authors use computational methods and experimental X-ray techniques to generate the XANES spectra of two different geometries of Fe(CO)5. Densities of states are used to show overlap between specific orbitals (Fe p with C p), indicating pi-backbonding.
Frank Neese was honored with the 2024 ACS Award in Inorganic Chemistry for outstanding accomplishments in combining high-level theory with experiment to obtain insight into the properties and reactivities of transition-metal complexes and metalloenzymes.
His major contributions to the field have been through the development and dissemination of his free computational modeling software program ORCA, which is used by thousands of researchers across the fields of inorganic and bioinorganic chemistry.
This LO was written by the IONiC Leadership Council to celebrate Steve Koch as the recipient of the 2024 ACS Award for Distinguished Service in Advancement of Inorganic Chemistry. Steve has been a major supporter of the IONiC community since its inception. This LO is based on the article New Members of the Class of [Fe(CN)x(CO)y] Compounds. published in Inorganic Chemistry (DOI: 10.1021/ic015604y).
Laboratory Project Summary:
Students in an upper level Inorganic Chemistry lab course are given a choice between two final lab projects. Both projects involve the synthesis of visible light-absorbing ruthenium complexes, however the subsequent application of these complexes correspond to different subfields within inorganic chemistry. This feature allows them to pursue a project that continues to develop their synthetic, data-analysis, and writing skills while pursuing one that most closely aligns with their interests.
This is an in class activity that I just used to replace a lecture! After students have the basic ideas of how to perform symmetry operations and put molecules in point groups, I like to reflect on the idea of a 'mathematical group' and what that means in terms of symmetry and group theory in inorganic chemistry.
