以H2L[N,N′-二(4-吡啶基)-2,6-吡啶羧酸二酰胺]为配体,分别与Zn(NO3)2·6H2O、CoCl2·6H2O在温和的实验条件下反应,得到了两个一维聚合物{[Zn(H2L)(N3)2]·CH3OH}n(1)和{[Co(H2L)2(SCN)2]·CH3OH·4DMF}n(2).用元素分析、红外光谱等进行了表征,并测定了其晶体结构.晶体结构表明,聚合物1的晶体属正交晶系,空间群为Pnna;聚合物2的晶体属单斜晶系,空间群为P2(1)/n.在这2个聚合物中,配体H2L两端的吡啶氮原子均以μ2-桥联的配位模式连接2个中心金属离子,而中心金属锌(II)为四配位的畸变四面体构型,钴(II)为畸变八面构型体构
With H2L [N, N’-bis (4-pyridyl) -2,6-pyridinecarboxylic acid diamide] as ligand, respectively, with Zn (NO3) 2 · 6H2O, CoCl2 · 6H2O under mild experimental conditions , Two one-dimensional polymers {[Zn (H2L) (N3) 2] .CH3OH} n (1) and {[Co (H2L) 2 (SCN) 2] .CH3OH.4DMF} n (2) were obtained. Its crystal structure was characterized by elemental analysis and infrared spectroscopy. The crystal structure showed that the crystal of polymer 1 was orthorhombic and the space group was Pnna. The crystal of polymer 2 was monoclinic, the space Group is P2 (1) / n. In these two polymers, the pyridine nitrogen atoms at both ends of the ligand H2L are connected to two central metal ions in a μ2-bridged coordination mode, while the central metal zinc (II) is Four-coordinated distorted tetrahedron configuration, cobalt (II) distorted eight-sided configuration
