Three hydrogen bond networks of cobalt(II) coordination polymers {[Co(btp) 2 (H 2 O) 2 ]·2(1,2‐Hbdc)·2H 2 O} n ( 1 ), {[Co(btp)(1,3‐bdc)(H 2 O)]·1.5H 2 O} n ( 2 ) and {[Co(btp) 2 (H 2 O) 2 ]·(1,4‐bdc)} n ( 3 ) were synthesized by 1,3‐bis(1,2,4‐triazol‐1‐yl)propane (btp) and benzenedicarboxylate position isomers. Complex 1 is comprised of [Co(btp) 2 (H 2 O)] n 2 n + 1D cation chains, 1,2‐Hbdc − anions and lattice water molecules. The structure of 2 is an undulated 2D (4,4) network. Two adjacent networks interpenetrate each other to form a new 2D double‐layers network which is sustained by the hydrogen bond interactions in 2 . Complex 3 is comprised of [Co(btp) 2 (H 2 O)] n 2 n + 1D cation chains and 1,4‐bdc 2− anions. These [Co(btp) 2 (H 2 O)] n 2 n + 1D cations and 1,2‐Hbdc − /1,4‐bdc 2− anions form 2D hydrogen bond networks in 1 and 3 . The thermal stabilities of 1 , 2 and 3 were investigated.
