Zinc complexes of the N,N,S ligand bis(pyrazolyl)(thienyl)methane
摘要:
The recently described ligand bis(pyrazol-1-yl)(thien-2-yl)methane (L3) was reacted with zinc halides with the aim of obtaining complexes with a tetrahedral Zn(N,N,S)Hal coordination. Molecular compounds L3ZnHal2 (Hal=Cl, Br, I) were obtained. A structure determination of the bromide complex showed it to be tetrahedral with two bromine and two pyrazole N ligand atoms. The thiophene sulfur was found to be non-coordinating.
