A hydroxo-bridged 1-D coordination polymer, [Cu(L)(H2O)]n (1), has been synthesized in good yield by employing a tetradentate Schiff base ligand, (6,6'-(1E,1'E)-(2-hydroxypropane-1,3-diyl)bis(azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)bis(2-methoxyphenol)), generated by condensation of o-vanillin with 1,3-diaminopropane-2-ol. Compound 1 has been fully characterized by elemental analyses, fourier transform IR, UV/vis and EPR measurements. Single crystal X-ray structure reveals that the central Cu-II atom adopts a distorted octahedral geometry, to form 1-D network manifesting by the bridging participation of hydroxo group from neighboring Schiff base unit. The magnetic behavior of 1 shows that the T-x(M) product at 300 K is 0.47 cm(3) kmol(-1). (c) 2012 Elsevier B.V. All rights reserved.
