摘要 A novel Mn(Ⅱ)coordination polymer(CP),[Mn(BBA)0.5(BIYB)]n(1),was gained by the 1,2,4,5-benzenetetracarboxylic acid(H4BBA),4,4-bis(imidazol-1-ylmethyl)biphenyl(BIYB),and Mn(CH3COO)2·4H2O under hydrothermal reaction.CP 1 was characterized and structurally determined by elemental analyses,PXRD,IR spectra,thermal behaviors,and X-ray single-crystal diffraction.The framework structure of 1 shows a novel(2,5,6)-connected 3Dnetwork with a Schlafli symbol of(4^3.6^6.8)^2(4^6.6^9)(6)^2.It crystallizes in triclinic system,space group P1,with a=7.5898(5),b=9.8201(6),c=14.1307(9)A,α=97.5850(10),β=99.6810(10),γ=111.6580(10)o,V=943.01(10)A3,Z=2,C23H15MnN 4O4,Mr=466.33,Dc=1.462 g/cm^3,F(000)=476,S=1.082,R=0.0361 and wR=0.1008.The magnetic property of CP 1 was investigated.The weak antiferromagnetic interactions are observed between the Mn(Ⅱ)ions.
