Abstract:

Tris(pyrazol­yl)borates are used extensively in metal coordination chemistry and belong to a class of ligands generally referred to as scorpionates. The steric and electronic properties of these ligands can be modified quite easily by varying the substituents on the 3-, 4-, and 5-positions of the pyrazolyl moieties on the B atom. Fluorinated tris­(pyrazol­yl)borates are useful in the stabilization of rare silver(I) complexes. The silver(I) adduct (aceto­nitrile-[kappa]N){tris[5-methyl-3-(tri­fluoro­meth­yl)pyrazol-1-yl-[kappa]N2]hydro­borato}silver(I), [Ag(C15H13BF9N6)(CH3CN)] or [HB{3-(CF3),5-(CH3)Pz}3]AgNCCH3, was ob­tained by treating [HB{3-(CF3),5-(CH3)Pz}3]Na with CF3SO3Ag in the presence of aceto­nitrile, and was isolated in 85% yield. Single-crystal X-ray diffraction analysis reveals that the AgI center has a pseudo-tetra­hedral all-nitro­gen coordination sphere, and is supported by a tris­(pyrazol­yl)borate ligand that binds to the AgI center in a [kappa]3-fashion.
