    • A mixture of water solution (10 mL) of 1,2-bis(4-pyridyl)ethylene (0.180 g, 1.0 mmol) and 5-nitro-isophthalic acid (0.211 g, 1.0 mmol) was added Co(NO3)2·6H2O (0.292 g, 1.0 mmol) and 0.75 mL triethylamine dropwisely to a stirring aqueous solution (5 mL) for 10 min at room temperature. The reactants were sealed in a 23-mL Teflon-lined autoclave heated at 140 °C for 4 days. Then red block crystals were obtained. The crystals were picked out, washed with distilled water and dried in air (Yield. ca. 62, based on Co, Calcd, ) for C56H36Co4N8O26: C, 45.67; H, 2.46; N, 7.61. Found C, 45.72; H, 2.53; N, 7.58.
