Three New Metal Complexes with Imidazole-Containing Tripodal Ligands as Fluorophores for Nitroaromatics- and Ion-Selective Sensing.

ABSTRACT: Three new metal-organic complexes [Cd(TIPA)(suc)_0.5(NO₃)·1/2H₂O]_n (1), [Ni(TIPA)(tda)_0.5(H₂O)·1/4H₂O]_n (2) and [Cd(TIPA)(tda)_0.5·11/2H₂O] (3) were synthesized via rigid tripodal ligand tris(4-(1H-imidazol-1-yl)phenyl)amine (TIPA) and three dicarboxylic acids; either succinic acid (H₂suc) or 2,5-thiophenedicarboxylic acid (H₂tda). Crystallographic data for 1 - 3 reveal three-dimensional (3D) networks and channels in the structures. The structure of 2 is unique featuring an interpenetrating 2D network, 2D + 2D → 3D, with the two associated 2D networks existing in two opposite spiral channels. TGA plots exhibit a loss of
