A new 3D Mn-II metal-organic framework compound {Mn(phen)(dcbP)}(n) (H(2)dcbp = 4,4-dicarboxy-2,2'-bipyridine, phen = 1,10-phenanthroline) was isolated under hydrothermal conditions and structurally characterized. In the compound, the dcbp ligand is deprotonated to give a neutral species (metal:ligand with 1:1 stoichiometry). Along the c axis, the neighboring Mn-II ions are linked by two carboxylate bridges in mu(2)-coordinating mode to generate a 1D zigzag chain, and these chains are interlinked by dicarboxylate groups of long dcbp ligands to generate a 3D (4,4)-connected structure with the (4(2).8(4)) net topology. IR and UV/Vis spectroscopy and variable temperature magnetic susceptibility measurements were made, which indicated weak antiferromagnetic interactions between the Mn-II ions of the compound.
