| 摘 要： | A trinudear Mn（II） coordination complex Mna （HEDTA）2-10H20 （EDTA=ethylene diamine tetraacetic acid） 1 has been synthesized and characterized by X-ray crystal structure determination. In addition, IR spectrum, thermogravimetric analysis, electron paramagnetic resonance （EPR） spectra and magnetic susceptibility of this complex are discussed. X-ray determination indicates that six- and seven-coordinate modes between Mn（Yl） and H4EDTA exist alternately in 1. Furthermore, detailed discussion of magnetic ordering in tile temperature range of 2-300 K reveals the antiferromagnetic interactions in the complex.

| Abstract: | A trinuclear Mn(II) coordination complex Mn3(HEDTA)2·10H2O (EDTA=ethylene diamine tetraacetic acid) 1 has been synthesized and characterized by X-ray crystal structure determination.
In addition, IR spectrum, thermogravimetric analysis, electron paramagnetic resonance (EPR) spectra and magnetic susceptibility
of this complex are discussed. X-ray determination indicates that six- and seven-coordinate modes between Mn(II) and H4EDTA exist alternately in 1. Furthermore, detailed discussion of magnetic ordering in the temperature range of 2∼300 K reveals
the antiferromagnetic interactions in the complex.
