Abstract: In the title compound, [Co(NO2)3(C17H25N3O6)]·H2O or [CoIII(NO2)3(pybox)]·H2O, where pybox is 2,6-bis[(4R)-(+)-4-isopropyl-4,5-dihydro-1,3-oxazol-2-yl]pyridine, the coordination geometry is distorted octahedral. This is the first reported complexation of the pybox molecule to a CoIII atom. The pybox ligand exhibits tridentate coordination to CoIII in a 1:1 ratio and the nitro anions occupy the remaining meridional positions of the octahedron. Molecules are linked, via solvent water molecules, into O-HO-N hydrogen-bonded chains.
