catena-Poly[[chloridocobalt(II)]-μ-5-(8-quinolyloxymeth­yl)tetra­zolato-κ(4) N (5),O,N (1):N (4)]

In the title compound, [Co(C(11)H(8)N(5)O)Cl](n), the Co(II) atom is penta­coordinated by one O atom and two N atoms from a 5-(8-quinolyloxymeth­yl)tetra­zolate ligand, one N atom from another symmetry-related ligand, and a Cl atom. The coordination geometry can be described as slightly distorted trigonal–bipyramidal. Adjacent Co atoms are connected by the bridging tetra­zole groups into a chain. The dihedral angle between the quinoline and tetra­zole planes is 21.2 (1)°. The structure involves intra- and inter­chain C—H⋯N hydrogen bonds.
