A mixture of TbCl3·6H2O (0.0373 g, 0.10 mmol), CuCl2·2H2O (0.0171 g, 0.10 mmol), H2pydc (0.0419 g, 0.25 mmol), NaOH (0.0020 g, 0.50 mmol), and H2O (6 mL) was sealed in a 10-mL Teflon-lined stainless steel container and heated at 170 C for 3 day. Upon being cooled to room temperature at a rate of 5 C/h, dark-blue block crystals were obtained in 43% yield (based on Cu). Anal. for C42H50N6O40Cu3Tb2 (%): C, 28.22; H, 2.82; N, 4.70. Found: C, 28.33; H, 2.74; N, 4.77.
