在甲醇、乙腈和DMSO混合溶剂中,偏钒酸版与双2-羟基-1-萘甲醛丙二酰腙在1,3-丙二胺存在下反应,得到一个新的氧钒席夫碱聚合物[VO(L).0.25CH3CN]n.通过红外光谱和X-射线单晶衍射对其进行了表征.晶体结构表明该化合物属于正交晶系,Pnma群,晶胞参数为:a=0.758 97(14)nm,b=2.232 7(4)nm,c=1.399 6(3)nm,V=2.371 7(8)nm3,Z=4.四齿配体和两个氧原子与钒配位,钒中心形成略扭曲的八面体构型,该化合物为一条[VO(L)]n链.配合物的热稳定和电化学性质在本文中也得到了研究和讨论.CCDC:703827.
In a mixed solvent of methanol, acetonitrile and DMSO, the partial-vanadate version was reacted with bis-2-hydroxy-1-naphthaldehyde malonyl hydrazone in the presence of 1,3-propanediamine to give a new vanadyl Schiff base polymerization The crystal structure of the compound [VO (L) .0.25CH3CN] n was characterized by IR and X-ray single crystal diffraction. The crystal structure showed that the compound belongs to the orthorhombic Pnma group with unit cell parameters of a = 0.758 97 (14) nm, b = 2.232 7 (4) nm, c = 1.399 6 (3) nm, V = 2.371 7 (8) nm3, Z = 4. The coordination of the tetradentate ligand and the two oxygen atoms to vanadium , The vanadium center forms a slightly distorted octahedron structure and the compound is a [VO (L)] n chain. The thermal stability and electrochemical properties of the complex have also been studied and discussed in this paper.CCDC: 703827.
