%X Compounds of copper(II) with chelated &#946;-imino alcohols are formed by reaction of 4-hydroxy-4-methylpentan-2-one, hmp, with copper(II) compounds of ethane-1,2-diamine, 2-methylpropane-1,2-diamine, meso-1,2- diphenylethane-1,2-diamine, 2-(pyridin-2-yl)ethanamine, 3-azapentane- 1,5-diamine and 4-azaheptane-1,7-diamine. A dinuclear, spin-coupled di- &#956;-olato bridged derivative of a &#946;-imino alkoxide, formed by reaction of hmp with 2-(pyridin-2-yl)ethanaminecopper(II), has a spin-coupling constant J of -286 cm-1, based on magnetic susceptibility data over the 100-300 K temperature range. A related compound formed by N,N- diethylethane-1,2-diamine, which could have an analogous structure containing water, or an isomeric structure with the &#946;-imino alcohol and with di-&#956;-hydroxide bridging, has a J value of about -130 cm-1, similarly determined. The preparation of a copper(11) compound with the tetradentate ligand 4,6-trimethyl-1,9-bis(pyridin-2-yl)-3,7-diazanon-3- ene, by reaction of bis[2-(pyridin-2-yl)ethanamine]copper(II) perchlorate with acetone, is reported.
