Hydrothermal reaction of CoCl2 with the potassium salt of pyridine-2,3-dicarboxylic acid and excess base yields [Co3(NC5H3(CO2)2-2,5)2(mu3-OH)2(OH2)2], which has a three-dimensional structure based on hydroxide-bridged triangular chains. The magnetic behavior of this compound shows the presence of three distinct regions of magnetic bistability.
