title: catena-Poly[[cadmium-bis-(μ-triethyl-ene-tetra-mine-κN,N':N'',N''')-cadmium-(μ-triethyl-ene-tetra-mine-κN,N':N'',N''')] hexa-fluoridogermanate].
abstract: The title fluoridogermanate, {[Cd(2)(C(6)H(18)N(4))(3)][GeF(6)]}(n), was synthesized hydro-thermally. The crystal structure comprises undulated cationic [Cd(2)(TETA)(3)](4+) chains (TETA is triethyl-ene-tetra-mine) propagating parallel to [101]. The central Cd(II) atom is six-coordinated in a CdN(6) set by three TETA ligands. The isolated [GeF(6)](2-) units, serving as counter-anions, occupy the inter-chain spaces and simultaneously link adjacent chains into a three-dimensional network through extensive N-H⋯F hydrogen-bonding inter-actions. One of the ethyl-ene bridges of one TETA ligand is disordered around a twofold rotation axis.
