摘要

A new Co(II) coordination polymer with complicated topology, namely [Co(bPP)(2)Cl(2)](n) (1) (bpp=1,3-bis(4-pyridyl)propane), has been designed and synthesized based on flexible ligand under basic condition. The complex was characterized by single-crystal X-ray analysis and infrared spectroscopy. The Coll ions are linked into a 3D structure via bpp molecules. Four independent frameworks are related by translation along the c tetragonal axis in the usual interpenetration topology for diamondoid frames.
