title: catena-Poly[cobalt(II)-bis-(μ-2-amino-ethane-sulfonato)-κN,O:O';κO:N,O'].
abstract: The hydro-thermally prepared title compound, [Co(C(2)H(6)NO(3)S)(2)](n), is isotypic with its Ni(II) analogue. The Co(II) cation is in a distorted octa-hedral environment, coordinated by four sulfonate O atoms and two N atoms from the taurine ligands. In comparison with the Ni(II) analogue, the Co-N and Co-O bonds are longer than the Ni-N and Ni-O bonds, whereas all other bond lengths and angles as well as the hydrogen-bonding motifs are very similar in the two structures. The sulfonate groups doubly bridge symmetry-related Co(II) atoms, forming polymeric chains along the a axis. N-H⋯O hydrogen bonding interactions consolidate the crystal packing.
