 Title    Synthese und Kristallstruktur des Lanthan-Titanat-Tellurats LaTi  
 Abstract    (Ti0 2 5Te0j 5)O6 und seine Verwandtschaft mit PbSb20 6 und Sr(MnTe)06 Synthesis and Crystal Structure of the Lanthanum Titanate Tellurate LaTi(Ti0 25Te0 75) 0 6 and its Relationship to PbSb20 6 and Sr(M nTe)06 L. Single crystals of LaTi(Ti0 25T e o .75) 0 6 have been prepared by solid state reactions. X-ray investigations led to trigonal symmetry, space group C3-P3 , a = 5.141(10), c = 5.218(10) A, Z = 1. The compound is characterized by a predominantly ordered distribution of Ti4+ and Te6+. Typical features of the crystal structure are staggered layers containing edge connected T i0 6 and (Ti,Te)06 octahedra. The layers are connected by La3+ ions receiving an octahedral coordination by the surrounding oxygen ions. The relationships to the PbSb20 6 type and the recently described compound Sr(M nTe)06 are discussed.
