catena-Poly[[tetra­kis­(1H-pyrazole-κN (2))copper(II)]-μ-hexa­fluoridosilicato-κ(2) F:F′]

In the title one-dimensional coordination polymer, [Cu(SiF(6))(C(3)H(4)N(2))(4)](n), the Cu(II) atom is coordinated by two hexafluoridosilicate F atoms and four pyrazole N atoms in a distorted trans-CuF(2)N(4) 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 Cu(II) 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.
