N-苯基亚氨基二乙酸(H2L),Mn(Ⅱ)和2,2′-联吡啶(2,2′-bipy)在50%甲醇中组装得标题配合物[MnL(2,2′-bipy)(H2O)].2H2O(1),其结构经IR,元素分析和X-射线单晶衍射表征。1属单斜晶系,空间群P2(1)/n,晶胞参数:a=0.885 9(3)nm,b=1.826 9(6)nm,c=1.385 7(5)nm,β=106.200(6)°,V=2.153 6(13)nm3,Z=4,F(000)=980,Dc=1.457 Mg.m-3。在1的晶体结构中,Mn(Ⅱ)为六配位的畸变八面体构型,其中2,2′-bipy的2个氮原子和羧基的2个氧原子位于赤道平面,L的氮原子和一个配位水分子处于轴向位置。1分子之间存在的氢键与π-π芳香堆积作用将其连接成三维超分子结构。
The title complex [MnL (2,2’-bipy) was assembled in 50% methanol with N-phenyliminodiacetic acid (H2L), Mn (II) bipy) (H2O)]. 2H2O (1), its structure was characterized by IR, elemental analysis and X-ray single crystal diffraction. 1 belongs to the monoclinic system with a space group of P2 (1) / n with a = 0.885 9 (3) nm, b = 1.826 9 (6) nm and c = 1.385 7 (6) °, V = 2.153 6 (13) nm3, Z = 4, F (000) = 980, Dc = 1.457 Mg.m-3. In the crystal structure of 1, Mn (Ⅱ) is a hexacoordinated distorted octahedral configuration in which two nitrogen atoms of 2,2’-bipy and two oxygen atoms of carboxyl group are located on the equatorial plane, and the nitrogen atom of L and A coordinating water molecule is in an axial position. Hydrogen bonds exist between 1 molecule and π-π aromatic stacking effect to connect them into three-dimensional supramolecular structure.
