![عکس صفحه اول مقاله: Syntheses and structures of two Zn(II) complexes with the pentadentate Schiff-base ligands Syntheses and structures of two Zn(II) complexes with the pentadentate Schiff-base ligands](/preview/png/1305098.png)
Two structurally divergent zinc complexes [Zn · H2L1 · Cl2] · 0.5CH3OH (1) and [Zn2 · L2 · Cl2 · (CH3OH)2] of the newly designed pentadentate H2N3O2 Schiff bases H2L1 and H2L2 have been synthesized and structurally characterized. 1 has one five-coordinated Zn(II) ion in a distorted square-pyramid while 2 contains one novel seven-coordinate ZnN3O4 core in a pentagonal bipyramid polyhedron and one ZnO2Cl2 core in a trigonal pyramidal geometry. The coordinated units in 1 and 2 are both linked by hydrogen bonds forming infinite one-dimensional zigzag chains.
Two new Schiff-base complexes [Zn · H2L1 · Cl2] · 0.5CH3OH (1) and [Zn2 · L2 · Cl2 · (CH3OH)2] (2) have been synthesized and structurally characterized. They have divergent structures though only possessing different positional methyls. Zn(II) in 1 is five-coordinated while 2 contains one novel ZnN3O4 core and one ZnO2Cl2 core. The coordinated units in 1 and 2 are both forming infinite one-dimensional hydrogen bond chains.Figure optionsDownload as PowerPoint slide
