Coordination polymers of bipyridyldicarboxylates - a cobalt containing 12,3-net with potential reactive sites

The porous cobalt(II) coordination polymer [Co{2,2 ' -bipy-4,4 ' (CO2)(2)}( H2O)(2)] (1) was prepared via a hydrothermal synthesis approach starting fr om Co(NO3)(2). 6H(2)O and 2,2 ' -bipyridine-4,4 ' -dicarboxylic acid in a o ne to one mixture of ethanol and water at 120 degreesC. The product was cha racterized by single crystal X-ray diffraction, TGA and elemental analysis. Space group: P3(1)21, unit cell dimensions at -73 degreesC: a = 11.980(2), c = 8.335(2) Angstrom, R = 0.032, wR(2) (all data) = 0.048. The structure determination revealed 1 to be a network in which octahedrally coordinated cobalt atoms are arranged to form a (12,3) net.
