Abstract: | In title anhydrous catena‐polytrans‐bis(ethane‐1,2‐diamine‐κ2N,N′)copper(II)]‐μ‐dithionato‐κ2O:O′], Cu(S2O6)(C2H8N2)2]n or {H2N(CH2)2NH2}2Cu(O·O2SSO2·O)]∞, 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) Å]. In title (hydrated) trans‐diaquabis(propane‐1,3‐diamine‐κ2N,N′)copper(II) dithionate, Cu(C3H10N2)2(H2O)2](S2O6) or {H2N(CH2)3NH2}2Cu(OH2)2](S2O6), both ions have imposed 2/m symmetry. The `axial' anion components are displaced by a pair of water ligands Cu—O = 2.439 (3) Å], the shorter Cu—O distance being compensated by the lengthened Cu—N distance 2.0443 (18), cf. 2.0100 (13) and 2.0122 (16) Å]. |
