5356por Oudahmane, Abdelghani, Daoud, Mohamed, Tanouti, Boumediene, Avignant, Daniel, Zambon, Daniel“…These chains, running along [100], are arranged in a pseudo-tetragonal rod packing and are further linked by isolated PrO(8) square antiprisms [Pr—O = 2.3787 (9)–2.5091 (8) Å], forming a three-dimensional framework. The K(+) ions reside in channels parallel to [010] and exhibit a highly distorted coordination sphere by eight O atoms at distances ranging from 2.7908 (9) to 3.1924 (11) Å.…”
