Abstract A noval cobalt(II) coordination polymer, {[Co(bpmb)(H 2 O) 2 (C 2 H 5 OH) 2 ]·(NO 3 ) 2 }‐ (1). where bpmb= N,N′‐ bis(3‐pyridylmethyl)‐1,4‐benzenedicarboxamide, was synthesized by self‐assembly of the two topic ligands with cobalt nitrate in ethanol solution, and characterized structurally by X‐ray crystallography analysis. The crystal data belong to triclinic, space group P 1 with cell parameters a=0.8911(3) nm, b=0.9042(3) nm, c= 1.0068(3) nm, α = 73.083(5)°, β=81.069(5)°, γ=76.210(5)°, R 1 =0.0518, wR 2 =0.0947 . The results of structure analysis indicate that each bpmb ligand coordinates two Co(II) atoms and each metal atom is in octahedral coordination geometry with four oxygen atoms of two ethanol and two water molecules, two nitrogen atoms from two different bpmb ligands in trans position forming an infinite 1D chain‐like structure. There BTC hydrogen bonding and π‐π stacking interaction among these chains, leading to supramolecular formation with 3D net structure.
