A new dimeric Mn(Ⅱ) complex,namely,[Mn(L)(PIP)]_2·H_2O(1),was synthesized under hydrothermal condition(H_2L = 3-carboxy-1-carboxymethyl-2-oxidopyridinium and PIP = 2-(pyridin-3-yl)-1H-imidazo[4,5-f][1,10]phenanthroline).It crystallizes in triclinic,space group P1 with a = 9.2037(13),b = 9.6794(13),c = 14.649(3) ?,α = 94.858(3),β = 94.928(3),γ = 114.468(2)o,V = 1172.9(3) ?~3,Z = 1,C_(52)H_(34)Mn_2N_(12)O_(11),Mr = 1112.79,Dc = 1.575 g/cm~3,F(000) = 568,μ(Mo Ka) = 0.618 mm~(-1),R = 0.0432 and w R = 0.1151.In 1,two L anions bridge two Mn(Ⅱ) atoms to give a dimeric [Mn(L)(PIP)] unit with the Mn···Mn distance of 3.009(2) ?.The two PIP ligands are located on both sides of the dimer,which provides suitable π-π stacking interactions between PIP ligands.By these π-π stacking interactions,adjacent dimers are extended into a two-dimensional supramolecular layer.Further,the strong N–H···O hydrogen bond stabilizes the supramolecular layer structure of 1.Moreover,the thermal behavior and luminescent property of 1 have been studied.

The two PIP ligands are located on both sides of the dimer, which provides suitable π-π stacking interactions between PIP ligands.By these π-π stacking interactions, adjacent dimers are extended into a two-dimensional supramolecular layer. Further, the strong N-H ·· O hydrogen bond stabilizes the supramolecular layer structure of 1. Core over, the thermal beh avior and luminescent property of 1 have been studied.
