A coordination polymer of cadmium nitrate with bridging ligand 1,3‐di(pyridin‐4‐yl)propane in which each cadmium ion has two chelated nitrate ions along with a water molecule is structurally characterised. Three component reactions of cadmium nitrate, 1,3‐di(pyridin‐4‐yl)propane together with 2,4‐dihydroxybenzaldehyde or 2,4‐dihydroxybenzaldoxime resulted in the formation of cadmium coordination polymers having 1,3‐di(pyridin‐4‐yl)propane as linkers encapsulating the aldehyde or the oxime in respective coordination polymer. These guest molecules are encapsulated between layers formed by hydrogen bonds among the chains of the coordination polymers where the nitro groups are vertically positioned in between the cationic chains assisting in formation of partitioned compartments to encapsulate guests. These guest included coordination polymers having the 2,4‐dihydroxybenzaldehyde or 2,4‐dihydroxybenzaldoxime guest molecules provided understanding on facilitation of the oximation reaction of aldehyde containing coordination polymer. Higher association ability of oxime over the aldehyde to the parent coordination polymer is found to be the driving force to facilitate the catalytic reaction.
