From a structural point of view the complexes with tertiary stibine ligands are very uniform. The predominant type is rj coordination (type 1), with electron pair donation of the Sb atom to the metal centre.1,2,6,8 However, complexes with bridging stibine ligands (type 2) are also known.13,14 (Scheme 1). 

Bridging coordination of a tertiary stibine ligand (type 2) occurs in binuclear complexes of rhodium (Equation 1).13,14... 

The most common nickel(O) complexes are those containing phosphorus, arsenic and antimony as donor atoms. Besides the Malatesta and Cenini book/1 which specifically deals with metal(O) complexes, nickel(O) complexes have been summarized in books and review articles which report complexes with phosphine, arsine and stibine ligands.31-37 Actually the nickel(O) complexes with these ligands amount to hundreds and the number of new complexes which are synthesized is increasing very rapidly, making nickel(0) phosphine chemistry a very extensive topic.

The single crystal X-ray structure of fra .y-[Ru(bipy)2(PPh3)2]2+1122,1123 and the synthesis of related bis(phosphine) complexes1005 have been reported. Reaction of [RuCljL ] (L = bipy,1124, 2-(aryl-azo)pyridine1066) with phosphine, arsine and stibine ligands (I/) affords the complexes [RuC1(L)2L ]+ while with bidentate ligands L [Ru(bipy)2L ]2+ can be isolated.1124 (See Section 45.5). 

Triphenylstibine Phs Sb and, less freqnently, trialkylstibines or bi- and tridentate stibine ligands, for example, CH2(SbPh2)2 and CH3C(CH2SbPh2)3 are nsed as donor ligands in transition metal complexes. (Cp3)3Sb is exceptional becanse it does not act as a donor but as an electron pair acceptor in the reaction with a carbene (eqnation 5). ...

A very large number of phosphine, phosphite, stibine, and arsine complexes of type four-coordinate [NiX2(ER3)2] and five-coordinate [NiX2(ER3)3] (X = halide) have been reported, although this area is dominated by complexes of tertiary phosphines. The complexes [NiX2(ER3)2] can be either tetrahedral (67) or square-planar (68), depending upon the electronic and steric effect of the coordinated phosphine, arsine, and stibine ligands (see Section 2). ...
