A novel one-dimensional zigzag chain-like Co II coordination polymer constructed from 4,4'-bi-pyridine (4,4'-bpy) and 2-hy-droxy-benzoate (2-OHbenz) ligands, namely, catena -poly[[(4,4'-bi-pyridine-κ N )-(μ-2-hy-droxy-benzoato-κ 2  O : O ')(2-hy-droxy-benzoato-κ 2  O , O ')cobalt(II)]-μ-4,4'-bi-pyridine-κ 2  N : N '-[aquahemi(μ-4,4'-bi-pyridine-κ 2  N : N ')(2-hy-droxy-benzoato-κ O (2-hy-droxy-benzoato-κ 2  O : O ')cobalt(II)], [Co 2 (C 7 H 5 O 3 ) 4 (C 10 H 8 N 2 ) 2.5 (H 2 O)]  n  , has been synthesized by reacting cobalt(II) nitrate trihydrate, 4,4'-bpy and 2-hy-droxy-benzoic acid in a mixture of water and methanol at room temperature. There are two independent Co II centers, Co1 and Co2, in the asymmetric unit, revealing a distorted octa-hedral geometry with chromophore types of [CoN 2 O 4 ] and [CoN 2 O 3 O'], respectively. The Co1 ions are doubly bridged by 2-OHbenz ligands with syn - anti coordination mode, generating a dinuclear unit. The bridging 4,4'-bpy ligands connect these dinuclear units and the mononuclear Co2 chromophores, providing a one-dimensional alternating zigzag chain-like structure. In the crystal, inter-molecular hydrogen bonds, C-H⋯π and π-π stacking inter-actions are observed and these help to consolidate the packing. In addition, the physical properties of the title compound are reported.
