摘要：

The crystal structures of [Fe-4(III)(HL)(2)(L)(6)(mu-O)(2)[PF6](2) . 4MeCN (1 . 4MeCN) and [Fe-2(III)(HL)(4) (OSO3)(2)(mu-O)]. 2MeOH . 3H(2)O (2 . MeOH . 3H(2)O) have been determined [HL is the ambidentate, potentially terdentate ligand 3-(2-pyridyl)-pyrazole] : complex 2 is a conventional mu-oxo-diiron(III) complex in which HL acts as a bidentate chelate and the sulfate ligands are monodentate, but 1 is effectively a dimer containing two mu-oxo-diiron(III) cores linked by deprotonated ligands L(-) which are bridging via the two N atoms of the pyrazolate rings.
