catena-Poly[[(1,10-phenanthroline-kappa(2)N,N')manganese(II)]-di-mu-salicylato-kappa(4)O:O'].

In the title polymeric complex, [Mn(C7H5O3)2(C12H8N2)]n, the MnII atom is located on a twofold axis and displays a distorted octahedral coordination geometry, formed by four salicylate anions and one 1,10-phenanthroline (phen) molecule. The salicylate anions doubly bridge the Mn(II) atoms to form one-dimensional polymeric chains. A comparison of Mn-O bond distances with the corresponding Mn-O-C angles suggests a significant electrostatic content in the Mn-O bonds. A face-to-face distance of 3.352 (7) A between neighbouring parallel phen planes indicates pi-pi stacking interactions between polymeric chains.
