The reaction between either SbCl3 or BiCl3 and three equivalents of Na[Ni (CO)(eta-C5Me5)] affords the trinickel-element complexes [ENi(CO)(eta-C5Me5)}3] (E = Sb, Bi). With two equivalents of Na[Ni(CO)(eta-C5Me5)], the dinickel complexes [EClNi(CO)(eta-C5Me5)}2] (E = Sb, Bi) are formed in solution, via the intermediacy of the trinickel compounds, although attempts to isolate these species led, in the case of bismuth, to the cluster compounds [Bi2Ni2(eta-C5Me5)2] and [BiNi3(eta-C5Me5)3]. All compounds were characterized by spectroscopic and analytical methods. Analogous reactions involving GaCl3 and InCl3 led only to intractable mixtures from which no pure compounds could be isolated. The reaction between Te(S2CNEt2)2 and two equivalents of Na[Ni(CO)(eta-C5Me5)] resulted not in a nickel-tellurium complex, but in the complex [Ni(S2CNEt2)(eta-C5Me5)], which was characterized by X-ray crystallography.
