An unusual zinc(II) coordination polymer [Zn5(OH)2(bbtz)2(bdc)4]n (1) [bbtz1,4‐bis(1,2,4‐triazol‐1‐ylmethyl)benzene, bdc1,2‐benzenedicarboxylate] was synthesized and characterized. 1 contains an unusual 2D network based on pentanuclear zinc(II) cluster [Zn5(OH)2]. Two adjacent pentanuclear Zn(II) clusters are bridged by four bdc ligands and extend to form the one‐dimensional chain. The bbtz ligands further link the one‐dimensional chains, resulting in a two‐dimensional coordination network. The luminescence and thermal stability were investigated.
