title: A new hydrated ammonium hydroxyborate, (NH(4))(2)[B(10)O(14)(OH)(4)].H(2)O.
abstract: The structure of a new synthetic compound, diammonium tetrahydroxydecaborate monohydrate, has been determined by single-crystal X-ray diffraction. It crystallizes in triclinic space group P-1 and all atoms occupy general sites. The title compound is composed of [B(10)O(15)(OH)(4)](4-) ions as the fundamental building blocks, and these are linked end-to-end by sharing two common O atoms, thus producing infinite chains of composition [B(10)O(14)(OH)(4)](n)(2n-). These chains are linked by hydrogen bonds, thus forming borate sheets. Water molecules and ammonium ions between these sheets connect adjacent sheets via hydrogen bonds.
