Abstract The synthesis and characterization of mononuclear [Cu (L) 2 (Cl) 2](1), dinuclear [{CuCl (L)} 2 (μ-Cl) 2](2), and another mononuclear complex [Cu (L) 2 (ClO 4) 2](3) with a bidentate N, N-diisopropylpicolinamide ligand (abbreviated L) are described. Complexes 1 and 2 were obtained from the same reaction mixture and show thermo-and solvatochromic behavior. Complex 1 shows irreversible thermochromism by changing into 2 upon heating ...
