Popis:	A (β-diketiminato)nickel(II) hydrazido(1–) complex [LtBuNi(η2-N2H3)], {1, LtBu = [HC(CtBuNC6H3{iPr}2)2]–} has been obtained by treatment of [LtBuNiBr] with hydrazine. In a reaction of 1 with two equivalents of the azo compound diisopropyl azodicarboxylic ester (adc–OiPr) the Ni(N2H3) entity acts as both a hydrogenating and a reducing agent: diisopropyl hydrazidodicarboxylate (hdc–OiPr) is formed, and more adc–OiPr is reduced by two electrons. The resulting (adc–OiPr)2– is found as a ligand in the ultimate nickel product complex, the trinuclear nickel(II) compound [LtBuNi(μ-adc–OiPr)Ni(μ-adc–OiPr)NiLtBu] (2), in which two LtBuNi+ units are linked by a [NiII(adc–OiPr)2]2– moiety. The hypothesis that LtBuNiI species are acting as intermediates was supported by the independent finding that 2 can also be obtained by reaction of [LtBuNi(OEt2)] with adc–OiPr.
