New quaternary titanium thiophosphates, Cs3Ti3(P4S13)(PS4)3 has been synthesized with the reactive halide flux and structurally characterized by single-crystal X-ray diffraction techniques. The compound is isostructural with Rb3Ti3(P4S13)(PS4)3. The structure of the compound is constructed by the interconnection of octahedral [TiS6] units and two types of thiophosphate ligands, [PS4]3- and [P4S13]6- anions. The [P4S13]6- anion is composed of three [PS4] tetrahedra sharing corners with one [PS4] group in the center of the star-like anion. The [TiS6] octahedra share two edges with the [PS4]3- tetrahedra in the sequence of –P-Ti-P-Ti-P- yielding an infinite helical chain. Two different type of helical chains are connected to form two different helical tunnels along the c-axis. As a guest ion, Cs+ cation intercalated into the empty channel with ionic interaction to stabilize the three-dimensional structure through electrostatic ionic interactions. The classical charge balance of the title compound can be described as [Cs+]3[Ti4+]3[PS43-]3[P4S136-].
