Compounds ∞ 1 [M(μ‐O 2 C‐C 6 H 4 ‐CO 2 )(NH 3 ) 2 ] crystallize as straight‐ (M = Cu) and kinked‐chain (M = Cd) coordination polymers through the bridging action of the bis‐mono (Cu) and bis‐bidentate (Cd) benzene‐1, 4‐dicarboxylate (terephthalate) ligand. N‐H···O hydrogen bonding connects the chains to a three‐dimensional supramolecular network. Thermogravimetry shows the compounds to be stable up to 255 °C (M = Cu) and 70 °C (M = Cd) where decomposition starts with the loss of one ammin ligand. ∞ 1 [Cd(μ‐O 2 C‐C 6 H 4 ‐CO 2 )(NH 3 ) 2 ] exhibits a luminescence with λ em, max = 392 nm (λ ex = 240 nm) on the same order of magnitude as Na 2 (O 2 C‐C 6 H 4 ‐CO 2 ).
