The fluoride (H3O)Yb3F10,H2O (SG:Fd3m,a=15.326(1) Å,Z=16) was synthesized in the form of powder by a “chimie douce” route. The compound δ-KYb3F10,H2O (SG:Fd3m,a=15.339(1) Å,Z=16), a new member of the KYb3F10family, was obtained by an acid–base neutralization. The structural description is based upon the stacking of [Yb6F32]14−“octahedral units of antiprism,” called UOA[8], where the three-dimensional [Yb6F20]2−network is simply a diamond type stacking of UOA[8]connected by vertices. The counterions are located in the middle of the chair hexagons. The zeolithic character of the water molecules is related to their mobility through the tunnels of this diamond structure. The simplifying description of this phase as a diamond type structure built up from UOA[8](A2[Yb6F20],2H2O,A=H3O+,Z=8) is the basis of our reexamination of the structural description of numerous complex structures built up of antiprisms.
