Abstract
The crystals of a heterobimetallic complex based on lead(II) hexafluoroacetyl acetonate and copper(II) trifluoroacetyl acetonate were investigated by X-ray diffraction. Crystal data for Cu(tfa)2⋅Pb(hfa)2: a = 9.3991(4) Å, b = 11.7816(5) Å, c = 13.9736(5) Å, α = 88.311(2)°, β = 89.972(1)°, γ = 76.326(1)°, space group P-1, Z = 2, dcalc = 2.190 g/cm3. The basic structural motif for the complexes is coordination polymer in the form of chains of alternating complex molecules. The Cu(tfa)2 molecules have a trans configuration. The results of a DTA-TG analysis of the compound are given.
