Abstract

AbstractA few compounds having the general formula M(L)+2 X− are reported, in which M(I) = Cu or Ag, X− = BF−4, NO−3, Cl−, Br−, and L stands for pyrazole, 3(5)‐methylpyrazole and 4‐nitropyrazole. The compounds are formed by reaction of MX and L in acidic medium. Infrared spectra of the compounds are consistent with linear cations ML+2 and uncoordinated anions.Apart from the above compounds, a different class of compounds is formed in less protic media. These compounds are salt like and have the formula M+L−, with M+ = Cu+ and Ag+ and L = pyrazole, 4‐iodopyrazole, 4‐bromopyrazole, 4‐ethylpyrazole, 4‐nitropyrazole and 3(5)‐methylpyrazole.Infrared spectra, mass spectra, X‐ray powder diagrams and solubility studies indicate that these compounds are at least trimeric and possibly polymeric with bridging pyrazolate anions between the metal ions.
