Dinuclear Cobalt(II), Iron(II), and Manganese(II), and Trinuclear Manganese(II) Complexes with Tridentate Ligands of NNS-Donor Set Derived from 2-Aminoethanethiol

Thiolate-bridged dinuclear cobalt(II), iron(II), and Manganese(II) complexes and trinuclear manganese(II) complexes of thiolic ligands, 2-[(2-aminoethyl)amino]ethanethiol, 2-[(3-aminopropyl)amino]ethanethiol, 2-[(2-pyridylmethyl)amino]ethanethiol, and 2-[[(2-pyridylethyl]amino]ethanethiol, were prepared and their magnetic properties were examined in the temperature range 80–300 K. The results indicated a significant antiferromagnetic spin-exchange interactions through the bridging sulfur atom for all the complexes.
