The structure of aqua(nitrato-O){pyridine-2,6-diylbis[N-(1-ethylideneamino)benzamide]-O1,N2,N1,N5,O2}cobalt(II) nitrate, [Co(NO3)(C23H21N5O2)(H2O)]NO3, was redetermined at 173 K. There are only small differences between the bond distances in the cation at 173 K relative to the room-temperature determination reported previously. The average difference is 0.006 Å for all 45 bond distances and only 0.004 Å for 27 bonds if the two phenyl rings and two nitrate ions, which have large thermal motions, are excluded. The CoII atom is in the center of a pentagonal bipyramid consisting of the pentadentate ligand, with a water molecule and monodentate nitrate ligand in the axial positions.
