The supra­molecular structure of a cadmium complex with the new functionalized terpyridine ligand 4'-[4-(pyrimidin-5-yl)phen­yl]-2,2':6',2''-terpyridine (L1): aqua­(L1-[kappa]³N,N',N'')(nitrato-[kappa]²O,O')(nitrato-[kappa]O)cadmium(II) dihydrate

The coordinating properties of the novel ligand 4'-[4-(pyrimidin-5-yl)phenyl]-2,2':6',2''-terpyridine were tested by reacting it with cadmium(II) nitrate. The resulting title complex presents a supramolecular motif dominated by a significant number of [pi]-[pi] interactions involving all the aromatic rings.
