title: Catena-poly[[trans-bis(ethane-1,2-diamine-kappa2N,N')copper(II)]-micro-dithionato-kappa2O:O'] and trans-diaquabis(propane-1,3-diamine-kappa2N,N')copper(II) dithionate.
abstract: In title anhydrous catena-poly[[trans-bis(ethane-1,2-diamine-kappa(2)N,N')copper(II)]-micro-dithionato-kappa(2)O:O'], [Cu(S(2)O(6))(C(2)H(8)N(2))(2)](n) or [[H(2)N(CH(2))(2)NH(2)](2)Cu(O.O(2)SSO(2).O)]( infinity ), successive Cu atoms are bridged by a single doubly charged dithionate group, forming a one-dimensional polymer with inversion centres at the metal atoms and the mid-point of the S-S bond [Cu-O = 2.5744 (15) A]. In title (hydrated) trans-diaquabis(propane-1,3-diamine-kappa(2)N,N')copper(II) dithionate, [Cu(C(3)H(10)N(2))(2)(H(2)O)(2)](S(2)O(6)) or [[H(2)N(CH(2))(3)NH(2)](2)Cu(OH(2))(2)](S(2)O(6)), both ions have imposed 2/m symmetry. The 'axial' anion components are displaced by a pair of water ligands [Cu-O = 2.439 (3) A], the shorter Cu-O distance being compensated by the lengthened Cu-N distance [2.0443 (18), cf. 2.0100 (13) and 2.0122 (16) A].
