13C-NMR, IR and Raman spectra are discussed; for the compound ClSb(CH2CH2CH2)2NMe the crystal structure analysis is given : the antimony atom is clearly Lewis acidic with ψ-trigonal-bipyramidal coordination and a transannular Sb⋯N interaction of 2.385(2) Å. For such a configuration ...
The nature of the Re–H–B interaction in 3 has been investigated by DFT, and the energetics for borane dissociation and hydride abstraction by the coordinated Lewis acid in 3 have also been computationally evaluated. The coordination of an oxygen in one of the ancillary CO groups by the ...

LEWIS-BASE ADDUCTSMOLECULAR-STRUCTURESOLID-STATEThe extension of systematic structural definition of arrays of the form MX:EPh3 (1:n) (M = univalent coinage metal, X = (pseudo-)halide, E = P, As. Sb, n = integer (1-4)) into complexes of chelate congeners with ligands of the form ...
The structures consist of individual complexes in which each gold atom has a linear coordination of one halogen atom and the S atom of the Lewis base. These complexes are arranged along the screw axis 41, forming an almost linear Au-Au chain with distances of 329 pm (X = Br) or 330 ...
The crystal structure of the acid-base adduct obtained from WO(CH2t-Bu)3Br and AlBr3 is described. The interaction between the Lewis acid and the oxo ligand of the tungsten compound is discussed on the basis of bond distances and bond angles in the Br W O Al linkage. The role of the...
