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

Abstract

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 from Co(NO3)2 · 6 H2O and 2,2′‐bipyridine‐4,4′‐dicarboxylic acid in a one to one mixture of ethanol and water at 120 °C. The product was characterized by single crystal X‐ray diffraction, TGA and elemental analysis. Space group: P3121, unit cell dimensions at –73 °C: a = 11.980(2), c = 8.335(2) Å, R = 0.032, wR2 (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.
