Dv. Pushkin et al., Specific features of coordination of antimony atoms in the complexes SbXn (X = F, Cl, Br, I), RUSS J IN C, 45(7), 2000, pp. 1063-1068
Stereochemistry of F-, Cl-, Br-, and I-containing antimony compounds is stu
died with the use of the Voronoi-Dirichlet (VD) polyhedra. The stereochemic
al activity of the lone pair electrons of Sb(III) atoms decreases with a de
crease in the electronegativity of the surrounding atoms along the series S
bFn-SbCln-SbBrn-SbIn. The intersecting spheres method can be used to determ
ine the coordination numbers of antimony atoms in crystals.
