With these ligands, two new dinuclear doubly-bridged-phenoxido copper(II) complexes (3, 4), and six more complexes (1, 2, 5\u20138), a new trinuclear complex (9) with an alternative doubly-bridged-phenoxido and \u2013methoxido, as well as the 1D polymer (10) were synthesized, and their molecular structures were characterized by spectroscopic methods and X-ray single crystal crystallography. The Cu(II) centers in these complexes exhibit distorted square-pyramidal arrangement in 1\u20134, mixed square pyramidal and square planar in 5, 6, and 9, and distorted octahedral (5+1) arrangements in 7 and 8. The temperature dependence magnetic susceptibility study over the temperature range 2\u2013300 K revealed moderate\u2013relatively strong antiferromagnetic coupling (AF) (|J| = 289\u2013145 cm\u22121) in complexes 1\u20136, weak-moderate AF (|J| = 59 cm\u22121) in the trinuclear complex 9, but weak AF interactions (|J| = 3.6 &amp; 4.6 cm\u22121) were obtained in 7 and 8.
