Solid-phase reaction of copper(I) chloride with sodium β-diketonates under mechanical activation in a vibration ball mill involves disproportionation of CuCl with the formation of the corresponding copper(II) β-diketonate and highly reactive X-ray amorphous metallic copper nanoparticles. The effect of reaction conditions on the process and some properties of the activated mixtures have been studied.

Bis(trifluoroacetylacetonato)copper(II), Cu(tfac)2, reacts with the nitronyl nitroxide radical 2,4,4,5,5-pentamethyl-4,5-dihydro1H-imidazolyl-1-oxy 3-oxide, NITMe, to yield a square-pyramidal adduct of formula Cu(tfac)2·NITMe. The X-ray crystal structure shows that it crystallizes in the space group P1, with a = 10.119 (5) A?, b = 12.159 (6) A?, c = 11.814 (5) A?, α = 115.13 (1)°, β = 85.30 (1)°, γ = 68.42 (1)°, and Z = 2. The distance of the copper ion from the oxygen of the axial NITMe is 2.303 A?. The magnetic data shows that the coupling is ferromagnetic, with a singlet-triplet splitting of 65 ± 5 cm-1. Structural-magnetic correlations for copper(II)-nitroxide complexes have been established through extended Hu?ckel calculations.
