Abstract

A new flexible tripodal 1,1 ',1 ''-(((1,3,5-triazin-2,4,6-triyl)tris(benzene-4,1-diyl))tris(methylene))tris(3-carboxypyridin-1-ium) bromide (H3taznaBr3) ligand and its new Manganese(II) compound, namely {[Mn(mu 6-tazna)]Cl2 center dot 4H2O}n(OGU - 1, OGU: Osmangazi University), were synthesized and structurally characterized by IR spectroscopy, elemental analysis, X-ray single-crystal and powder diffraction techniques. Single crystal X-ray diffraction analysis revealed that the OGU - 1 is 3D framework, possessing 1D channels along the b-axis with dimensions of 9.39 x 13.63 angstrom 2, in which 1D channels are filled with chloride ions and lattice water molecules. The OGU - 1 displayed a 6,6-connected net with a point symbol of {48.66.8}{49.66}. Furthermore, thermal (TG, DTA and DTA) and photochromic properties of the OGU - 1 were investigated and it exhibited color change under 365 nm UV light.
