- Abstract
X-ray diffraction structural study is carried out for crystals of a heterobimetallic complex derived from lead(II) hexafluoroacetylacetonate and copper(II) 2-methoxy-2,6,6-trimethylheptan-3,5-dionate prepared by co-crystallization of Pb(hfa)2 and trans-Cu(zis)2. In the novel compound Cu(zis)2·Pb(hfa)2 the copper complex is found to have cis-configuration. It is demonstrated that the main structural motif of this complex is coordination dimers Cu(zis)2·Pb(hfa)2 joint in polymeric chains of alternating molecules of the complexes. Crystal data for Cu(zis)2·Pb(hfa)2: a = 9.848(2) Å, b = 23.871(5) Å, c = 18.289(4) Å, β = 100.23(3)°, space group P21/ n, Z = 4, d x = 1.701 g/cm3. The distance Pb-Cu in the dimer is 3.68 Å.
