Crystal structure of the salt bis­(tri­ethano­lamine-κ(3) N,O,O′)cobalt(II) bis­[2-(2-oxo-2,3-di­hydro-1,3-benzo­thia­zol-3-yl)acetate]

The reaction of 2-(2-oxo-2,3-di­hydro-1,3-benzo­thia­zol-3-yl)acetic acid (NBTA) and tri­ethano­lamine (TEA) with Co(NO(3))(2) results in the formation of the title complex, [Co(C(6)H(15)NO(3))(2)](C(9)H(6)NO(3)S)(2), which is formed as a result of the association of bis­(tri­ethano­lamine)­cobalt(II) and 2-(2-oxo-2,3-di­hydro-1,3-benzo­thia­zol-3-yl)acetate units. It crystallizes in the monoclinic centrosymmetric space group P2(1)/c, with the Co(II) ion situated on an inversion centre. In the complex cation, the Co(II) ion is octa­hedrally coordinated by two N,O,O′-tridentate TEA mol­ecules with a facial distribution and the N atoms in a trans arrangement. Two ethanol groups of each TEA mol­ecule 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 hy­droxy groups of the TEA mol­ecules are involved in hydrogen bonding with the O atoms of NBTA anions, forming an infinite two-dimensional network extending parallel to the bc plane.
