Popis:	The magnetic susceptibilities of compounds [Cu(4-XPhO)2(L)] (4-XPhOH = phenol, 4-nitrophenol, 4-chlorophenol; L = 1,2-diaminoethane, N,N,N′,N′-tetramethylethylenediamine) and [Cu(salaz)(RCOO)] (Hsalaz = 8-(2-hydroxyphenyl)-1,5- diazabicyclo[3.2.1]octane; R = CH3–, C2H5–, (CH3)3C–) were determined over the temperature range of 77—300 K, and compared with those for salicylideneaminato-bridged compounds. The correlation between their structures and exchange-coupling strength were formulated to indicate that the exchange couplings for phenoxo-bridged copper(II) systems were affected not only by the p character of the hybrid orbitals on the bridging oxygen atom, but also by the electronic effects of the substituents on the aromatic ring.
