利用5-(4-吡啶基)四唑(4-PTZ)与氯化锰合成了一种新型的超分子配合物[Mn(4-PTZ)2(H2O)4].2H2O,通过X-射线单晶衍射技术对其进行了表征。结果分析表明:该配合物属三斜晶系,空间群为P-1,晶胞参数a=0.7315(4)nm,b=0.7859(5)nm,c=0.8682(5)nm,α=90.909(8)。,β=91.738(8)。γ=100.400(8)。,Z=1。配合物由1个Mn原子、2个4-PTZ、4个水分子和2个结晶水分子构成。Mn原子的配位数为六,并处于八面体的配位环境,分别与4个水分子的氧原子和来自2个4-PTZ上的N原子配位。通过各种氢键作用形成了二维网状结构,进而层与层之间的氢键和π-π堆积作用将该化合物扩展为三维空间结构。
A novel supramolecular complex [Mn (4-PTZ) 2 (H2O) 4] was synthesized with 5- (4-pyridyl) tetrazole (4-PTZ) Single crystal diffraction technology to characterize it. The results show that the complex belongs to the triclinic system with space group P-1. The unit cell parameters are a = 0.7315 (4) nm, b = 0.7859 (5) nm, c = 0.8682 (8). , β = 91.738 (8). γ = 100.400 (8). , Z = 1. The complex consists of one Mn atom, two 4-PTZs, four water molecules and two crystal water molecules. The coordination number of Mn atoms is six, and in octahedral coordination environment, they coordinate with oxygen atoms of four water molecules and N atoms from two 4-PTZ respectively. The two-dimensional network structure is formed through various hydrogen bonds, and further, the compound is expanded into a three-dimensional space structure by hydrogen bonding and π-π stacking between the layers.
