Three pillared-layered inorganic–organic hybrid polymers, namely, [Cu 2 (4,4′-Hbpt)(SCN) 2 ] n ( 1 ), [Cd(4,4′-Hbpt)(SCN) 2 ] n ( 2 ), and [Cd(4,4′-Hbpt)(SCN) 2 ·CH 3 CN] n ( 3 ) were synthesized via layer diffusion methods. In all three complexes, there exist 2-D neutral wave-like d 10 metal thiocyanate layers (for 1 , [Cu 2 (SCN) 2 ] n , and for 2 and 3 , [Cd(SCN) 2 ] n ) with (4, 4) topology, which are further connected by bidentate 4,4′-Hbpt ligands to form 3-D structures with the primitive cubic topology. The results of photoluminescence and thermogravimetric analyses indicate that the three complexes are good candidates as luminescent materials. This paper provides a strategy to synthesize a novel family of pillared-layered inorganic–organic hybrid polymers constructed with layered d 10 metal thiocyanate layers and conjugated organic spacers at the molecular engineering level, as well as the discovery of new patterns of crystallization at the crystal engineering level.
