Crystal Structure And Magnetic Properties Of A One-Dimensional Polymer [Mn(Im2-Py)(Tp)(H2o)(2)]Center Dot 1.25h(2)O

A new manganese(II) complex [Mn(im2py)(tp)(H2O)(2)](.)1.25H(2)O (im2-py = 2-(2'-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl and tp = terephthalato dianion) has been synthesized and characterized structurally and magnetically. The crystal structure consists of neutral chains of manganese(II) ions linked by the terephthalate ligand. Variable temperature magnetic susceptibility data exhibit a weak antiferromagnetic coupling between the manganese(II) ion and the imino nitroxide radical.
