Compounds of copper(II) perchlorate with 2-aminoethanol (etol) and 3- aminopropan-1-ol (prol) react with 4-amino-4-methylpropan-2-one (amp), and with 4-hydroxy-4-methylpropan-2-one (hmp), to form compounds of stoichiometry [Cu(L)] ClO4, where (L) is a tridentate amine imine olato ligand from amp, or a hydroxy imine olato ligand from hmp. The etol condensation products have 'normal' magnetic susceptibilities, while the prol condensation products show antiferromagnetic spin-coupling. The prol/amp product is diamagnetic at 300 K (-J > 700 cm-1) and the prol/hmp product has a J of -186 cm-1, based on magnetic susceptibility measurements over 100-300 K. Preparations of some related nitrate, thiocyanate and tetrachlorozincate compounds are reported. Possible structures for the compounds are discussed.
