A ID coordination polymer of {[Mn(HL)(phen)(H2O)2] ?1.5H2O}n (H3L=2-hydroxy-5-carboxybenzene-sulfonic acid, phen=l,10-phenanthroline) has been synthesized and characterized by elemental analysis, IR, TG, PL, UV, powder and X-ray single crystal diffraction. The title complex crystallized in monoclinic with space group C2/c, a=0.840 57(17) nm, 6=1.757 5(4) nm, c=2.873 4(6) nm, /3=92.54(3)°, and K=4.240 7(16) nm3,2=4, ?=0.027 0. Each Mn(II) ion is six-coordinated by two oxygen atoms from one HL2" dianion, two N atoms from one phen ligand, and two coordinated water molecules, thus defining a slightly distorted octahedron coordination geometry. The oxygen atoms from sulfonate and carboxyl group link adjacent Mn(II) ions to form ID chains, which are further connected by intermolecular hydrogen-bonding interactions, generating a three-dimensional supramolecular network. Moreover, aromatic π-π stacking interactions between phenyl rings of HL2" dianion and phenanthrolines were detected.
