A novel 3D Mn(II) coordination polymer involving 4,4 '-dipyridylsulfide and 4,4 '-dipyridyltrisulfide obtained by in situ ligand formation from 4,4 '-dipyridyldisulfide

A new coordination polymer, {[Mn(mip)(dps)](dpts)(0.5)}(2n) (1) (mip = 5-methylisophthalate) has been solvothermally synthesized by in situ generation of 4,4'-dipyridylsulfide (dps) and 4,4'-dipyridyltrisulfide (dpts) ligands from a 4,4'-dipyridyldisulfide (dpds) precursor. The coordination framework of 1 shows a new (3,5)-connected 3-D net topology with a Schlafli symbol of (4(2).6(5).8(3))(4(2).6), in which weak antiferromagnetic interactions are observed between the Mn-II ions.
