A new 1D coordination polymer,{[Mn_2(4',4-hbc)_4(4',4-Hhbc)_2(H_2O)]·H_2O}_n(4',4-Hhbc=4'-hydroxyl-biphenyl-4-carboxylic acid),has been hydrothermally synthesized and structurally characterized by elemental analysis,IR spectroscopy and single-crystal X-ray diffraction.The crystal belongs to the monoclinic system,space group C2/c with a=52.421(10),b=7.5388(15),c=16.478(3)A,β=106.12(3)°,V=6256(2)A~3,Z=4,C_(78)H_(62)Mn_2O_(21),M_r=1445.16,D_c=1.534g/cm~3,μ(MoKa)=0.490 mm~(-1),F(000)=2992,R=0.0764 and wR=0.2006 for 2984 observedreflections with I＞2σ(I).X-ray diffraction analyses reveal that the title compound is a onedimensional infinite chain,in which the Mn~Ⅱ atom adopts a distorted octahedral geometry coordinated by four 4',4-hbc ligands,one 4',4-Hhbc ligand and one water molecule.Furthermore,the luminescent property of title compound was investigated.
