| 摘要: 用凝胶扩散法合成了2个新型的配位聚合物{[Zn(bpdc)(H2O)2]·H2O}n(1)和[Cd(bpdc)(H2O)2]n(2)(H2bpdc=4，4′-联苯二甲酸)。X-射线单晶衍射分析表明配合物1属于单斜晶系，C2/c空间群，晶胞参数为a=0.693 66(11) nm，b=3.160 7(5) nm，c=0.626 80(9) nm，β=96.467°；配合物2属于正交晶系，Pnma空间群，晶胞参数为a=0.586 69(7) nm，b=2.914 1(4) nm，c=0.786 63(10) nm。热重分析和荧光光谱分析表明配合物1和2的热稳定性较好，与游离配体相比其荧光的发射波长发生红移而强度明显增强。 |

| Abstract: Two coordination polymers {[Zn(bpdc)(H2O)2]·H2O}n(1) and [Cd(bpdc)(H2O)2]n(2) (H2bpdc=4, 4′-biphenyldicarboxylic acid) had been synthesized by gel diffusion method. The crystal structure has been determined by X-ray single crystal diffractometry. The results revealed that compound 1 crystallized in monoclinic system with space group C2/c, a=0.693 66(11) nm, b=3.160 7(5) nm, c=0.626 80(9) nm, β=96.467°, and compound 2 crystallized in orthorhombic system with space group Pnma, a=0.586 69(7) nm, b=2.914 1(4) nm, c=0.786 63(10) nm. The complexes were stable up to 400 ℃, and had strong emission at room temperature. CCDC: 800390, 1; 800393, 2. |
