Abstract: The dimeric molecule of the hydrothermally synthesized binuclear complex [Cu₂(C₂H₆NO₃S)₂(ClO₄)₂(C₁₀H₈N₂)₂], a tauride complex, occupies a special position on an inversion centre. The Cu atom has a severely distorted octahedral coordination, with four short and two substantially longer bonds. The four short bonds involve two bipyridine and one taurine N atoms [Cu-N_bipyridine = 1.990  (3) and 2.025  (3)  Å, Cu-N_taurine = 1.992  (3)  Å] as well as one of the taurine O atoms [Cu-O = 1.964  (3)  Å]. The second taurine O atom belonging to the second bridging molecule forms a much longer Cu-O bond [2.363  (4)  Å], and the perchlorate O atom participates in the longest Cu-O bond [2.675  (3)  Å]. The molecules are linked via N-HO bonds into infinite chains running along the a axis of the crystal structure.
