%X Singlet ground state compounds of nickel(II) with tetradentate &#946;-imino amine ligands are formed by reaction of complexes of ethane-1,2- diamine, propane-1,2-diamine, 3-azapentane-1,5-diamine, 4-azaheptane- 1,7-diamine and (2-aminoethyl)piperazine with 4-amino-4-methylpentan-2- one, amp. With 3,6-diazaoctane-1,8-diamine, a compound with a pentadentate &#946;-imino ligand is formed, water completing octahedral coordination, and with 2-aminoethanol a bis compound of a tridentate &#946;-imino amine alcohol ligand is formed. More complex products are formed by the hydrazone and oxime of amp. The oxime compound shows appreciable antiferromagnetism, with the spin-coupling constant, J, about -70 cm-1, determined from magnetic susceptibility measurements over 100-300 K.
