Completing the bis­[hy­droxy­bis(pyridin-2-yl)methane­sulfonato-[kappa]3N,O,N']MII series (M = Mn to Zn) with the copper(II) and cobalt(II) structures

Abstract: The CuII complex bis­[hy­droxy­bis­(pyridin-2-yl)methane­sul­fon­ato-[kappa]3N,O,N']copper(II) hexa­hydrate, [Cu(C11H9N2O4S)2]·6H2O, (I), crystallizes in the space group P\overline{1}, compared with P21/c for the anhydrous CoII analogue bis­[hy­droxy­bis­(pyridin-2-yl)methane­sulfonato-[kappa]3N,O,N']cobalt(II), [Co(C11H9N2O4S)2], (II). However, both mol­ecules sit on a crystallographic inversion centre and are thus very similar in appearance. Jahn-Teller elongation of the Cu-O bonds [2.347 (3) Å in (I) and 2.064 (2) Å in (II)] influences the S-O bond lengths, which are all around 1.455 (3) Å in (I) and 1.436 (2)-1.473 (2) Å in (II).

Formula: [Cu(C11H9N2O4S)2]·6H2O and [Co(C11H9N2O4S)2]
