用溶液法和水热法分别合成了2个含2-苯氧基丙酸配体(HL)的聚合物{[NiL2(H2O)2(bipy)].2H2O}n(1)、{[ZnL2(bipy)].2H2O}n(2)(bipy=4,4′-联吡啶),用元素分析、红外光谱、热重和单晶X-射线衍射对产物进行了表征。在化合物1中,镍原子与2个羧基氧原子、2个配位水氧原子及2个4,4′-联吡啶的2个氮原子配位,配位数为6,镍原子的配位构型为畸变的八面体;而在化合物2中,锌原子与2个羧基氧原子及2个4,4′-联吡啶中的2个氮原子配位,锌原子的配位构型为畸变的四面体。在这2个化合物里,4,4′-联吡啶通过氮原子连接金属原子形成一维链状。链间氢键与π-π堆积作用又将一维链链接成二维层状结构。
Two polymer {[NiL2 (H2O) 2 (bipy)] 2H2O} n (1) and {[ZnL2 (bipy)] 2H2O} n (2) (bipy = 4,4’-bipyridine). The product was characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. In the compound 1, the nickel atom is coordinated to two nitrogen atoms of two carboxyl oxygen atoms, two coordinating water oxygen atoms and two 4,4’-bipyridyls, and the coordination number is 6, and the coordination of the nickel atom In the compound 2, the zinc atom is coordinated with two carboxyl oxygen atoms and two nitrogen atoms in two 4,4’-bipyridines, and the coordination configuration of the zinc atom is distorted Tetrahedron. In these two compounds, 4,4’-bipyridine is connected to the metal atom through the nitrogen atom to form a one-dimensional chain. Inter-chain hydrogen bonds and π-π stacking effect in turn links one-dimensional chain into two-dimensional layered structure.
