trigonal pyramidal geometry in the solid state, readily reacts in solution with organichalides (CH3I, C2H5Cl, C3H7Cl, C6H5Cl, C6H5Br, C6H5I and C6H5CH2Cl) to give nickel(I) species with formula [NiX(np3)], (X Cl, Br, I). Benezene, biphenyl, o-, m-, p-chlorobiphenyl are the other products from the reaction between the title complex and chlorobenzene.

The ethoxycarbonyl complex [(np3)Ni(CO2Et)]BPh4 (2) [np3 = tris(2- diphenylphosphinoethyl)amine] has been synthesized by ethoxide ion attack on (np3)Ni(CO) (3) or [(np3)Ni(CO)]BPh4 (4). Compound 2 reacts with LiHBEt3, NaBH4, MeMgI, NaC10H8, or MeLi to give the carbonyl 3, whereas with BH3·THF it gives the complexes [(Hnp3)Ni(CO)]BPh4 (6) and [(np3)NiH]BPh4 (7). The mechanism of the reactions leading
