The new compound Na2Cu2ZrS4 has been synthesized through direct reaction of the elements with an Na2Sn flux at 375°C. The structure has been determined by single-crystal X-ray methods. The compound crystallizes in space group C32h − C2/m of the monoclinic system with two formula units in a cell of dimensions a = 13.657(9), b = 3.720(3), c = 7.025(5) Å β = 112.44(3)deg; (T = 113 K). The structure is composed of 2∞ [Cu2ZrS42-] layers separated by Na+ cations. A 2∞ [Cu2ZrS42−] layer is composed of pairs of CuS4 tetrahedra alternating with ZrS6 octahedra.
