Abstract

A new pentadentate ligand, α,α,α′,α′- tetra(pyrazolyl)lutidine, pz4lut, has been prepared by a CoCl 2-catalyzed rearrangement reaction between 2,6- pyridinedicarboxaldehyde and dipyrazolylthione. The coordination chemistry with some divalent first-row transition metal (Mn, Fe, Co, Ni, Cu, and Zn) chlorides has been explored. The electronic properties indicate that the new κ5N ligand is a slightly stronger-field donor to Ni 2+ and Co2+ than a related pentadentate ligand with five pyridyl donors presumably because of greater interaction between the metal and axial pyridyl.
