Soc., 133, 4172, 10.1021/ja109437d A mixture of L, 4-(((1 H-imidazol-2-yl)methylene)amino)benzoic acid (56.2mg, 0.2mmol) and Cd(NO3)2·4H2O (61.7mg, 0.2mmol) in DMF (8mL) and THF (8mL) solvents, was placed in a 25mL Teflon-lined stainless steel vessel, heated to 85°C for 2days, and then cooled to room temperature over 24h. Yellow crystals of 1 were obtained. Yield: 34.62mg (63% based on Cd). Elemental analysis (%): calcd for (C15H17CdN3O4): C 43.34, H 4.12, N 10.11; found: C 42.73, H 4.57, N 11.36.
