Abstract

The ligand class of tridentate bis(pyrazolyl)methanes was extended via the syntheses of HC(3,5-EtPz)(2)Py. This ligand is the first of its kind with a homogeneous 3,5-functionalization with large substituents. On the basis of 3,5-functionalized ligands we were able to synthesize 15 novel complexes with Fe-II, Zn-II, and Cu-II salts. Herein we present an extensive coordination chemistry study, that focuses on the influences of different metals, ligands, and counterions on the coordination mode and on the spin state in case of Fe-II complexes.
