A new triple tungstate RbAgSc(WO) (0 ≤ x ≤ 0.15) synthesized by solid state reactions and spontaneous crystallization from melts presents a new structure type related to those of CsNaYb(MoO) and NaSrTa(PO). The title compound in centrosymmetric space group Cmcm contains dimers of two ScO octahedra sharing corners with three bridging WO tetrahedra.

- A new triple molybdate compound, RbAgIn(MoO), was synthesized and characterized, exhibiting a unique crystal structure that supports two-dimensional ionic conductivity.
- The compound's structure features interconnected octahedra and trigonal prisms, forming a 3D framework and incorporating Rubidium atoms in its cavities.
- Notably, RbAgIn(MoO) shows a first-order phase transition at 535 K, accompanied by a significant increase in electrical conductivity, making it a promising candidate for high-temperature ionic conductivity applications.
