Poly[[μ3-2-(benzotriazol-1-yl)acetato-κ3O:O′:N3]chlorido(ethanol-κO)cobalt(II)]

In the title compound, [Co(C8H6N3O2)Cl(C2H5OH)]n, the CoII atoms adopt octahedral trans-CoN2O4 and tetrahedral CoCl2O2 coordination geometries (site symmetries \overline{1} and m, respectively). The bridging μ3-O:O:N 2-(benzotriazol-1-yl)acetato ligands connect the octahedral cobalt nodes into (010) sheets and the CoCl2 fragments link the sheets into a tri-periodic network. The structure displays O—H...O hydrogen bonding and the ethanol molecule is disordered over two orientations.
