The Synthesis and Electronic Structure of [NiX4]2- Complexes and the Role of Crown Ethers in Inorganic Synthesis

Literature Discussion

Submitted by Wesley S. Farrell, United States Naval Academy

This literature discussion aims to have students in an advanced inorganic chemistry course interpret reaction schemes and electronic spectra, relate chemical formulae to molecular structure, and gain an understanding of how inorganic synthesis is planned and executed.  Students should gain an understanding of how counterions and crown ethers affect structure. Question 7 may be expanded to ask students to why pi-donor ability affects ligand field splitting, or as an introfuction to this topic.

An associated 1FLO based on this paper is linked in the related content.

Learning Goals: 
Students will be able to:
  • Interpret reaction schemes and write balanced equations.
  • Rationalize the position of a ligand in the spectrochemical series based upon its π-donor/acceptor properties
  • Relate the electronic structure of tetrahedral d8 complexes to their magnetic properties
  • Analyze the impact of countercations on the geometry and electronic properties of the complexes.
Implementation Notes: 

This LO is intended for an advanced inorganic chemistry course.  Students should read the communication before class with questions above as guidance.  A classroom discussion should insue, in which students gain an insight into inorganic synthesis, and recognize how minor differences between compounds, such as counterions, have significant effects on electronic structure.


Time Required: 
50 minutes
Evaluation Methods: 

The classroom discussion (participation, answers, etc) may be assessed by the instructor, or alternatively, these questions could be given to students to turn in.
