The complexes [cis-andTiCl2(g3-digol)(THF)], [YCl3(g3-H2digol)(THF)], [Mg2(l-Cl)2(g3-H2digol)2(THF)2]Cl2have been synthesized and structurally characterized by X-ray diÜraction.[Na2(l,g2-H2digol)2(g3-Hdigol)2]Complex1consists of a dichlorotitanium(IV) core with a doubly deprotonatedmer-coordinated tridentate 2,2@-oxydiethanlato(2[) and THF ligands. Compound2has a distorted pentagonal bipyramidal structure withchlorine ligands in the axial positions. In thecation of3, each magnesium[Mg2(l-Cl)2(g3-H2digol)2(THF)2]2`atom is octahedrally coordinated by twol[Cl atoms, the chelate tridentateligand and the oxygeng3-H2digolatom of the coordinated THF molecule. The structure of4includes two six-coordinated sodium atoms linked bytwo OH bridges. Three oxygen atoms ofg3-Hdigol and one ether oxygen atom of theligandsg2-H2digolcomplete the coordination sphere of the sodium atoms. One of the oxygen atoms of thehydroxylg2-H2digolgroup remains uncoordinated.
