Two novel bidimensional coordination polymers, [Co­(azbbpy)­(4,4′-bipy)0.5(DMF)­(NCS)2]·MeOH (1) and [Co­(azbbpy)­(bpe)0.5(DMF)­(NCS)2]·0.25H2O (2), resulted from the assembling of cobalt­(II) ions by 1,3-bis­(4-pyridyl)­azulene, using either 4,4′-bipyridyl or 1,2-bis­(4-pyridyl)­ethylene as neutral spacers. The cobalt­(II) nodes in 1 and 2 act as single-ion magnets (SIMs).
