title: Crystal structure of the salt bis-(tri-ethano-lamine-κ(3) N,O,O')cobalt(II) bis-[2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetate].
abstract: The reaction of 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetic acid (NBTA) and tri-ethano-lamine (TEA) with Co(NO3)2 results in the formation of the title complex, [Co(C6H15NO3)2](C9H6NO3S)2, which is formed as a result of the association of bis-(tri-ethano-lamine)-cobalt(II) and 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetate units. It crystallizes in the monoclinic centrosymmetric space group P21/c, with the Co(II) ion situated on an inversion centre. In the complex cation, the Co(II) ion is octa-hedrally coordinated by two N,O,O'-tridentate TEA mol-ecules with a facial distribution and the N atoms in a trans arrangement. Two ethanol groups of each TEA mol-ecule form two five-membered chelate rings around the Co(II) ion, while the third ethanol group does not coordinate to the metal. The free and coordinating hy-droxy groups of the TEA mol-ecules are involved in hydrogen bonding with the O atoms of NBTA anions, forming an infinite two-dimensional network extending parallel to the bc plane.
