A new 1D coordination polymer,{[Mn2（4＇,4-hbc）4（4＇,4-Hhbc）2（H2O）]·H2O}n（4＇,4-Hhbc=4＇-hydroxyl-biphenyl-4-carboxylic acid）,has been hydrothermally synthesized and struc-turally 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）,β=106.12（3）°,V=6256（2）3,Z=4,C78H62Mn2O21,Mr=1445.16,Dc=1.534g/cm3,μ（MoKα）=0.490mm-1,F（000）=2992,R=0.0764 and wR=0.2006 for 2984 observed reflections with I2σ（I）.X-ray diffraction analyses reveal that the title compound is a one-dimensional infinite chain,in which the MnⅡ 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.
