The title compound, tripotassium sodium tritin octaselenide, K3NaSn3Se8, has a molecular (zero-dimensional) structure containing trimeric [Sn3Se8]4- units which consist of three edge-sharing SnSe4 tetrahedra. The [Sn3Se8]4- anions and the tetrahedrally coordinated Na+ cations are arranged in an alternating fashion along the c axis to form SiS2-like chains, which are then separated by eight-coordinate K+ cations. The Sn-Se bond distances are normal, being in the range 2.477 (1)-2.612 (1) angstroms.
