Bis(μ-2-aminoethanesulfonato)-κ2N,O:O′;κ2O′:N,O-bis[(bipyridine-κ2N,N′)(perchlorato-κO)copper(II)]

The dimeric molecule of the hydrothermally synthesized binuclear complex [Cu-2(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) Angstrom, Cu-N-taurine = 1.992 (3) Angstrom] as well as one of the taurine O atoms [Cu-O = 1.964 (3) Angstrom]. The second taurine O atom belonging to the second bridging molecule forms a much longer Cu-O bond [2.363 (4) Angstrom], and the perchlorate O atom participates in the longest Cu-O bond [2.675 (3) Angstrom]. The molecules are linked via N-H...O bonds into infinite chains running along the a axis of the crystal structure.
