The hydrothermal hydrolysis reactions of Cd(ClO 4 ) 2 ·(6H 2 O) with 4‐[2‐(2‐pyridyl)ethenyl]benzonitrile (2‐PEBN) and 2‐[2‐(4‐cyanophenyl)ethenyl]‐8‐quinolinol (2‐CEQH) afforded two coordination polymers aquabis{4‐[2‐(2‐pyridyl)ethenyl]benzoate}cadmium( II ) ( 1 ) and 2‐[2‐(4‐carboxylatophenyl)ethenyl]‐8‐quinolinolate(pyridine)cadmium( II ) ( 2 ), respectively. Complexes 1 and 2 display strong blue and red fluorescent emission, respectively. Both 1 and 2 have a 2‐D grid framework containing a dimer as the corner unit. Crystal data for 1 : monoclinic, P 2 1 / c , a = 15.2411(2), b = 19.8651(2), c = 15.6929(1) Å, α = β = 90, γ = 96.961(1)°; for 2 : monoclinic, P 2 1 / c , a = 11.9219(1), b = 8.9515(1), c = 18.8204(1)Å, α = γ = 90.00, β = 104.372(1)°.
