ABSTRACT
Trirubidium trititanium undecatelluride, Rb(3)Ti(3)Te(11), has been synthesized from the reaction of titanium, tellurium, and Rb(2)Te(3) at 773 K. Its structure has been determined from single-crystal X-ray data. It is composed of one-dimensional [Ti(3)Te(11)(3-)] chains built by face-sharing pentagonal TiTe(7) bipyramids and distorted TiTe(6) octahedra. These chains adopt hexagonal closest packing along the [101] direction. Rb atoms are located among these chains. The wide range of Te-Te interactions makes the assignment of formal oxidation states impossible. The compound is isostructural with Cs(3)Ti(3)Te(11).
