Zinc and Cadmium Derivatives of Tris(1-Pyrazolyl)Methane

Abstract

Tris(1-pyrazolyl)methane, L, gives thermally stable LMX₂, L₂MI₂, and octahedral [L₂M]Z₂ species, where M is zinc or cadmium, X may be Cl, Br, I, or trifluoroacetate, and Z is perchlorate or tetrafluoroborate. Conductivity, infrared, and nmr spectra (¹H and ¹³C), show that these compounds are not stable in the few solvents in which they dissolve, i.e. dimethylsulphoxide and, to a lesser extent, methanol due to ligand displacement.
