| Abstract: | Three coordination complexes of formula Ni(L1)2(H2O)4].4H2O (1), Mn(L2)2(H2O)4] (2) and Mn(L2)2(H2O)2]n (3) L1H = 6-methylpyridine-3-carboxylic acid, L2H = 3-(3-pyridyl)acrylic acid] have been synthesized and structurally characterized by X-ray single crystal analysis. A 3D network is achieved through H-bonding in 1 and 2, while crystal packing of complex 3 shows a 3D supramolecular coordination polymer. Thermal properties have been investigated by thermogravimetric analysis. Luminescence study features the presence of LMCT and metal purterbed ligand centered emission bands. |
