摘要

Equimolar reactions between ZntBu(2) and diphenyl phosphate (dpphe-H) or dimethyl phosphate (dmphe-H) result in the formation of [tBuZn(O2P(OR')(2))]-type compounds which crystallize as tetranuclear aggregates, [tBuZn(dpphe)](4) (1(4)) or [tBuZn(dmphe)](4) (2(4)), with the phosphate ligands spanning 4-coordinate Zn centers. The utility of ZnMe2 instead of ZntBu(2) dramatically changes the reaction outcome and leads to [MeZn(O2P(OR')(2))]-type moieties incorporating zincoxane units, i.e., pentanuclear [{MeZn(dpphe)}(3)(Me2Zn2O)(THF)(2)] (3) and nonanuclear [{MeZn(dmphe)}(6)(Me2Zn3O2)] (4) aggregates. The resulting compounds were characterized by H-1 and P-31 NMR spectroscopy and single-crystal X-ray diffraction analysis.
