give S6 symmetric, hexanuclear aggregates with the general formula 12(ZnR)6 (R = Me 2a, Et 2b), when 1a reacts with diethylzinc, solvent dependent reactions take place. If dichloromethane is used for the reaction solvent, a dimeric, C2 symmetric, tetranuclear product with the formula 1a2Zn2(ZnEt)2 (3) is isolated while in diethyl ether, a C2 symmetric, pentanuclearaggregate 1a2Zn(ZnEt)4 (4) forms, and
