The new quaternary layered compound [Co1.5Pt0.5]Ta6PtSe16 has been prepared and structurally characterized. This compound crystallizes in the monoclinic system (C32h- C2 m, a = 13.089(18), b = 3.425(3), c = 24.436(25) Å, and β = 104.9(1)°) with two formula units in the cell. The structure contains Ta atoms in both trigonal prismatic and octahedral sites, Co atoms in a square-pyramidal environment, and Pt atoms with both square-pyramidal and square-planar coordination. This compound is related to the Co2Ta4PdSe12 structural type where an additional TaSe2 unit has been added to the chains of metal atoms.
