Abstract in Englisch:

Dimeric, base-stabilized organozinc alkoxides [dmap-Zn(R)μ-OR]2 (R = Et 1; i-Pr 2), were obtained from reactions of ZnR2 and 4-dimethylaminopyridine (dmap) in the presence of O2. Their solid state structures were determined by single crystal X-ray diffraction studies. 1 is triclinic, space group P-1 with a = 8.0639(10) Å, b = 8.3082(11) Å, c = 10.4545(13) Å, α = 70.846(2)°, β = 72.316(2)°, γ = 81.505(2)° and Z = 1. 2 is triclinic, space group P-1 with a = 8.6381(6) Å, b = 9.2773(7) Å, c = 10.2186(7) Å, α = 112.094(1)°, β = 103.040(1)°, γ = 92.598(1)° and Z = 1.
