A One-dimensional Manganese(Ⅱ)Coordination Polymer with 4'-Hydroxybiphenyl-4-carboxylate as the Single Ligand: Synthesis, Crystal Structure and Luminescence

摘要

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 I>2σ(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.
