Hydrothermal synthesis has afforded succinate (suc) or 2,2-dimethylsuccinate (dmsuc) perchlorate coordination polymers with divergent dimensionality incorporating the kinked hydrogen-bonding capable diimine tethering ligand 4,4'-dipyridylamine (dpa): {[Co(suc)(HdPa)(2)(H(2)O)(2)](CIO(4))(2) center dot 7.5H(2)O}(n) (1),{[Cd(3)(suc)(2.5)(dpa)(2)](ClO(4))}(n) (2) and {[Cd(2)(dmsuc)(2)(dpa)(Hdpa)](ClO(4)) center dot 6H(2)O}(n) (3). Influenced by coordination geometry preferences, compound I manifests simple cationic one-dimensional (1D) [Co(suc)(Hdpa)(2)(H(2)O)(2)](n)(2n ) polymeric chains, while 2 possesses a unique three-dimensional (3D) binodal (5,6)-connected (4(6)6(4))(4(10)6(5)) network. The network of 2 can also be viewed as alternating (4,4) rectangular and (6,3) hexagonal grids being joined by pillaring ligands. The steric bulk imparted by the gemdimethyl substituents within the dmsuc ligands results in a two-dimensional (2D) (6,3) herringbone net in 3. The d(10) derivatives 2 and 3 undergo blue-violet luminescence upon exposure to ultraviolet radiation.
