title: Completing the bis[hydroxybis(pyridin-2-yl)methanesulfonato-κ3N,O,N']M(II) series (M = Mn to Zn) with the copper(II) and cobalt(II) structures.
abstract: The Cu(II) complex bis[hydroxybis(pyridin-2-yl)methanesulfonato-κ(3)N,O,N']copper(II) hexahydrate, [Cu(C(11)H(9)N(2)O(4)S)(2)]·6H(2)O, (I), crystallizes in the space group P1, compared with P2(1)/c for the anhydrous Co(II) analogue bis[hydroxybis(pyridin-2-yl)methanesulfonato-κ(3)N,O,N']cobalt(II), [Co(C(11)H(9)N(2)O(4)S)(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).
