Two manganese(II) and bismuth(III) complexes of the formulae [Mn(H2O)6]·H2bptc (1) and (H2bipy)2[Bi2Cl10]∙2H2O (2) (H4bptc = 3,3′,4,4′-biphenyltetracarboxylic acid, bipy = 4,4′-bipyridine) were synthesized. The complexes were characterized by elemental analyses, single-crystal X-ray diffraction, powder X-ray diffraction, infrared spectra, and thermal analyses. Structurally, 1 is a mononuclear complex with a triclinic space group P1‾. 2 is a dinuclear complex and it is built of two Bi3+ ion cores bridged through two Cl− ions. Furthermore, the result of fluorescence showed that 1 had fluorescent property. And the nanometer manganese oxide was prepared using 1 as a precursor. In addition, the photocatalytic activity of 2 on the degradation of Rhodamine B (RhB) was investigated and a possible photocatalytic mechanism was proposed. The Mn(II) and Bi(III) complexes were synthesized and characterized. The fluorescence property of 1 was investigated and the manganese oxide nanoparticles were prepared with 1 as the precursor. 2 exhibited good activity for the photocatalytic decomposition of Rhodamine B.
