The coordination polymer, {[Co(tart)(phen)] · 6H 2 O} n ( 1 ) (tart, tartrate dianion; phen, 1,10‐phenanthroline) has been synthesized and characterized by single‐crystal X‐ray structure determination, magnetic measurement and thermal analysis. The structural analyses reveal two adjacent parallel 1D–[Co(phen)‐tart‐Co(phen)]– coordination polymers zipped through π‐π interactions. The lattice water molecules, forming a 1D water cluster, function as glue to form a 3D supramolecular network through an extended hydrogen bonding. A comparison highlighting the structural differences with the corresponding 2,2′‐bipyridine (bpy) derivative, {[Co(tart)(bpy)] · 5H 2 O} n ( 2 ) containing a less amount of lattice water molecules is discussed. The variable‐temperature magnetic study of 1 has been carried out and interpretation of the already reported complex 2 has been re‐visited: both polymers 1 and 2 show weak antiferromagnetic interaction.
