Molecular Structures and Spin‐States of Pseudohalide Metal Complexes with Hydrazones of Girard's T Reagent

Pseudohalide metal complexes with hydrazones of the Girard T reagent are reviewed with respect to their synthesis, characterization, structures (both in solution and in the solid state), and magnetic properties. It is hoped that this microreview might serve as a concise guide to the chemistry of pseudohalide metal complexes with hydrazones of the Girard T reagent. The structural versatility of pseudohalide metal complexes with the Girard T hydrazine is summarized in this microreview, with special focus on their spin states and magnetic properties.
