catena-Poly[[tetra­kis­(1H-pyrazole-κN2)copper(II)]-μ-hexa­fluoridosilicato-κ2F:F′]

In the title one-dimensional coordination polymer, [Cu(SiF6)(C3H4N2)4]n, the CuII atom is coordinated by two hexafluoridosilicate F atoms and four pyrazole N atoms in a distorted trans-CuF2N4 octa­hedral environment. The dihedral angle between the planes of the pyrazlole rings in the asymmetric unit is 74.4 (3)°. The hexa­fluoridosilicate dianion acts as a bridging ligand, connecting the CuII atoms into a [1-10] chain. The Cu and Si atoms lie on special positions with 2/m site symmetry. In the crystal, intra­chain N—H⋯F hydrogen bonds occur and weak C—H⋯F inter­actions link the chains.
