Özet

New dispiro-dipyridyloxy-cyclotriphosphazene ligand (L) was successfully synthesized and treatment of the synthesized ligand with AgPF6 afforded a new coordination polymer, namely {[Ag(L)]center dot(PF6)center dot(CH3CN)}(n) (1) in the current study. L was fully characterised using a range of analytical techniques which included infrared and nuclear magnetic resonance spectroscopy, mass spectrometry and elemental analysis. Also, L and 1 were structurally determined by X-ray crystallography. Slow evaporation of n-hexane-CH2Cl2 (3:1) solution of L yielded block type crystals in a monoclinic system with space group P21/n, whereas 1 organized in orthorhombic morphology with Pbmc space group in acetonitrile. L showed kappa N-3 coordination mode with Ag(I) ions in complex 1 giving one-dimensional-chain (1D) polymeric structure. IR spectra revealed that the P -N stretching frequencies of the complex (1) showed some changes when compared to free ligand (L). TGA analysis of Land coordination polymer 1 showed that thermal stability of L is higher than complex (1). (C) 2017 Elsevier B.V. All rights reserved.
