Summary Two new series of polynuclear complexes with potentially chelating amine and nitrite as ligands have been synthesized from octahedral dinitritobis(diamine)nickel(II) complexes (diamine = en, pn, tn or chxn). These complexes have been characterized by chemical analysis, electronic and i.r. spectra and magnetic measurements down to nitrogen liquid temperature. An x-ray structural investigation shows one of the starting materials, [Ni(tn)2(NO2)2] to contain NO 2 − groups coordinatedvia N(nitro complexes). One of the series of formula [Ni5(diamine)4(NO2)8(OH)2], is pentanuclear, analogous to the en complex, whose structure is known. Another series is the polymeric Ni(amine)2(NO2)X, also an analogue of the en derivative. In the first series, the formation and isolation of the pentanuclear species has been achieved with en, tn, pn and chxn, but in the second series, only polynuclear complexes with en, tn and pn, were obtained. No product could be isolated for the more bulky chxn.
