主　　题：Mn(Ⅱ)聚合物 2,2-联吡啶-3,3-二羧酸 晶体结构 合成 

摘      要：A Manganese(Ⅱ) polymer {[Mn(bpdc)(bipy)(H2O)]·4.5H2O}n has been synthesized (bpdc=2,2-bipyridine- 3,3-dicarboxylate,bipy=4,4-bipyridine) and characterized by IR, UV, elemental analysis and X-ray crystal structure determination . It crystallizes in Monoclinic system, space group P2/n with a=1.010 13(8) nm, b=1.164 66(9) nm, c= 2.147 40(16) nm, β=98.22 20(10)°, V=2.500 4(3) nm3, Z=4, Dc=1.467 g·cm-3, F(000)=1 144, R1=0.049 0, wR2= 0.141 2. The crystal structure shows that the Mn2+ ions have octahedral coordination geometry with two coordination situations. The Mn2+ (1) ion is coordinated with two N atoms of two bipy, and chelated by four O atoms from four carboxylate groups of two bpdc ligands. The neighbor Mn2+ (2) ion is coordinated with two oxygen atoms from two water, two N atoms of two 4,4-bipy and two O atoms from two carboxylate groups of two bpdc ligands. Mn(1) and Mn(2) ions are bridged by bpdc and bipy ligands, forming a novel 2D network. CCDC: 651043.
