Synthesis and Crystal Structure of a Manganese Coordination Polymer [（phen）MnCl2]n

1 INTRODUCTION Polymeric manganese complexes with fascinating topological chemistry have received considerable interest[1, 2]. The complexation of phen with man- ganese ion gives rise to a wide variety of coordi- nation complexes; however, (phen)Mn coordina- tion polymers are rare since the chelation of phen results in 1 to 3 5-membered chelating rings, ob- structing the way towards the coordination poly- mer. Similar situation has also been observed for 2,2?-bipyridine (bpy) which has si…
