Sequestering Hydrated Fluoride in a Three-Dimensional Non-Interpenetrated Octahedral Coordination Polymer via a Single-Crystal-to-Single-Crystal Fashion

A three-dimensional non-interpenetrated octahedral channel type coordination polymer [{Cu(L1)2(Cl)}·Cl·(H2O)4]∝ (1) (L1 = N,N′-bis-(3-pyridyl)terephthalamide) possessing an inclusion of chloride water cluster [Cl(H2O)4]− exhibits sequestering of partially hydrated fluoride [F(H2O)4]− via a single-crystal-to-single-crystal fashion as evident from single crystal X-ray diffraction and solid state 19F NMR.
