Abstract
The cocrystallization method is used to obtain a new volatile heterometallic complex of the composition [Cu(ki)2·Pb(hfa)2]2, where ki = 2-iminopentan-4-onate and hfa = hexafluoroacetylacetonate. The crystallographic data for C20H18CuF12N2O6Pb: a = 10.6729(5) Å, b = 10.7712(5) Å, c = 13.4779(5) Å; α = 79.1020(10)°, β = 84.5140(10)°, γ = 66.2470(10)°, Р-1 space group, Z = 2, dx = 2.102 g/cm3. The compound has a molecular structure built of individual Cu…Pb…Pb…Cu-type tetramers. The Cu…Pb and Pb…Pb distances in the tetramer are 3.454 Å and 4.122 Å respectively; the Cu-Pb-Pb angle is 160.7°.
