Conclusions
-
1.
The results of small-angle x-ray scattering by the lithium tetraalkylborates Li[t-C4,H9OB(OR)3] (R=C3H7, i-C4,H9, C7Hi15 C13H27) and their structured solutions confirm the association of the complexes by means of the alkyl substituents; the degree of association depends on the dielectric constant of the solution and the length of the alkyl substituent.
-
2.
The radii of inertia and the maximum dimensions of the associates have been determined for structured solutions of the complexes.
-
3.
The shape of the associates of the complexes is nearly cylindrical. The mean volume of the associates of the complex is 1·104 to 1.5·104 Å3.
