Two new CuII/WVI oxyfluorides, catena-poly[(trifluorooxotungsten)-μ-fluoro-[diaquabis(pyridine­N)copper]-μ-oxo] or catena-poly[(difluoro-cis-dioxotungsten)-μ-fluoro-[diaquabis(pyridine­N)copper]-μ-fluoro], [CuW-O2F4(C5H5N)2(H2O)2], (I), and catena-poly[(trifluorooxotungsten)-μ-fluoro-[tetrakis(pyridine-N)copper]-μ-oxo] or catena-poly[(difluoro-cis-dioxotungsten)-μ-fluoro-[tetrakis(pyridine­N)copper]-μ-fluoro], [CuW-O2F4(C5H5N)4], (II), have been synthesized. The first complex, (I), contains one-dimensional chains of alternating [Cu(py)2(H2O)2(O/F)2/2]+0.66 cations and [W(O/F)4(O/F)2/2]−0.66 anions. The corner-linked octahedra form infinite and parallel chains that run along the b axis. The second compound, (II), contains one-dimensional chains of alternating [Cu(py)4(O/F)2/2]+0.66 cations and [W(O/F)4(O/F)2/2]−0.66 anions. The corner-linked octahedra form infinite and non-intersecting chains that switch between [110] and [1\bar 10] every c/2.
