Construction of Bimetallic and Trimetallic Aggregates with a [Y(COT)<sub>2</sub>]<sup>-</sup> Building Block: Solid-State Structures and Solution Behavior.
Ontology highlight
ABSTRACT: Several new bimetallic and trimetallic complexes containing the [Y-(COT)2]- unit in different coordination environments are synthesized and fully characterized using X-ray crystallography and NMR spectroscopy. These complexes include [K([2.2.2]-cryptand)]-[Y-(COT)2] (1), [K-(18-crown-6)-(THF)]-[Y-(COT)2] (2), [Y2K2(COT)4(THF)4] (3), and [YKCa-(COT)3(THF)3] (4). In the presence of secondary ligands, bimetallic ionic pairs that comprise a [Y-(COT)2]- sandwich and a solvent-wrapped K+ ion are formed in 1 and 2. In contrast, 3 represents a bimetallic tetradecker oligomer with two [Y-(COT)2]
