title: Dipotassium aquapentafluorovanadate.
abstract: The title compound, K(2)[VF(5)(H(2)O)], was synthesized from potassium antimony tartrate, piperazine, V(2)O(5) and HF under hydrothermal conditions. It is isostructural with K(2)[FeF(5)(H(2)O)] and contains polymeric anion chains held together by strong O-H...F bonds. Each V atom is coordinated to five terminal F atoms and the O atom of one water molecule. Pairs of O-H...F bonds are formed by two cis-related F atoms. Twofold axes run along the O-V-F axis of the V-centred otahedra.
