Abstract
The pseudobinary system NaOH/NaBr is investigated by X-ray methods. Th e structure of the compound Na5Br(OH)(4) was solved by single crystal data: Na5Br(OH)(4): Pnma, Z = 8, a = 11.846(2) Angstrom, b = 18.782(4) Angstrom, c = 6.431(1) Angstrom, Z(F-o) = 1202 with (F-o)(2) greater than or equal to 3 sigma(F-o)(2), Z(parameter) = 100, R/R(w) = 0.030/0 .035 The compound crystallizes in a new type of structure. Pairs of oc tahedra around O by 5 Na and 1H to [Na-5(OH)](2) are orientated in suc h a way to one another that two ions OH- form a parallelogram hinting to unusual bent hydrogen bridge bonding.
