Abstract:
The reaction of LiN(SiMe(3))(2) with 1 equiv of HOCH(2)CMe(3) (HONep) in toluene led to the formation of [Li(mu3-ONep)](8) (1). The complex adopts a novel dual-edge fused hexagon-square prismatic structure with a C(2v) axis of rotation that relates the top and bottom eight-membered rings. Substituting the noncoordinating solvent toluene for a Lewis basic solvent (THF or py) led to the isolation of compounds of the general formula [Li(mu3)-ONep)](4)(solv)(3), where solv = THF (2) or py (3). The cube structures of 2 and 3 have one Li which is not solvated because of steric crowding of the ONep ligands. Multinuclear solid-state ((6)Li, (7)Li, and (13)C) MAS and solution-state ((1)H, (7)Li, and (13)C) NMR studies were undertaken to verify the identity of the bulk powder and to determine the solution behavior of these compounds.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
