Tertiary stibines, R3Sb, are the most frequently used antimony ligands and the coordination chemistry of these donors to transition metals of the groups 3-12 and also to main group 13 and 15 elements has been reviewed several times, often together with other pnicogen ligands.1,2,6-8... 

Mixed organo antimony ligands with one or two electronegative groups have been only rarely used in transition metal chemistry. The resulting complexes belong to type 3 or 4 with -Sb coordination (Scheme 2). 

Fig. 10b) are similar. In all these complexes the antimony ligand is coordinated to the transition metal center in the apical position. The angles around the four coordinated antimony atom (100.8-106.8° in [(CO)4Fe(ri1-Ph2Sb-CH2-SbPh2)], 99.4-104.9° in [(CO)5W(V-Ph2Sb-CH2-SbPh2)], and...

The lability of the E-E and E-C bonds in cyclostibines and cyclobismuthines is readily evident in reactions of these homocycles with metal carbonyls. Under mild conditions, complexes in which the antimony ligand acts as a two-electron donor towards the metal centres may be isolated, e.g. cyclo-( BuSb)4[W(CO)5] (n=l,2) cf. metal complexes of cyclophosphines, see Section 7.1.1). In boiling solvents, however, rupture of the inorganic homocycle and/or the E-C bonds...
