| Abstract: | Interaction of LOEtZrF3] ( = Co(η5-C5H5){P(O)(OEt)2}3]−) (1) with 3 equivalents of bis(trimethylsilyl) sulfate afforded the ZrIV hydrogensulfato complex (LOEt)2Zr2(SO4)2(HSO4)2] (2) that reacted with Et3N to give Et3NH]LOEtZr(H2O)(SO4)2] (3). Treatment of complex 1 with 3 equivalents of trimethylsilyl acetate afforded LOEtZr(OCOCH3)3] (4), whereas that with 1 and 2 equivalents of trimethylsilyl trimethylsiloxyacetate yielded LOEtZrF(OCOCH2O)]2 (5) and LOEtZr(OCOCH2OH)(OCOCH2O)]2 (6), respectively. The crystal structures of complexes 2 and 6 have been determined. |
