Shape-anisotropic　nanomaterials　with　uniform　lengths　and　widths　have　attracted　much　interest　but　few　of　them　are　involved　in　self-assembled　manganese　complexes.　The　combination　of　two　redox-active　acylthiosemicarbazide　ligands　with　Mn3+　cations　leads　to　two　discrete　polynuclear　Mn　nanorods,　pentanuclear　[Mn-5(L3)(6)][Mn-0.7(DMF)(1.4)(H2O)(2.8)]　(1a)　and　trinuclear　Mn-3(L4)(3)center　dot　2DMF　(2),　whose　L3　and　L4　represent　N-(5-(2-hydroxyphenyl)-1,3,4-oxadiazol-2-yl)benzamide　and　N-(5-(2-hydroxyphenyl)-1,3,4-oxadiazol-　2-yl)-propionamide,　respectively,　which　are　in　situ　synthesized　from　their　acylthiosemicarbazide　derivatives　in　the　presence　of　Mn3+　cations,　while　the　latter　are　reduced　into　divalent　ones　in　rod-like　moieties.　For　each　pentanuclear　anion　in　1a,　the　charge　is　balanced　by　a　solvated　trivalent　manganese　cation,　which　can　be　replaced　by　two　tetramethylammonium　cations　to　yield　pure　valence　compound　1b.　Moreover,　the　magnetic　studies　reveal　all　of　them　possess　antiferromagnetic　properties.
