A new ternary potassium cobalt stannide, K 13 CoSn 17– x ( x = 0.1), was obtained by reacting the mixture of the corresponding pure elements at high temperature, and structurally characterized by single‐crystal X‐ray diffraction study. K 13 CoSn 17– x ( x = 0.1) crystallizes in the orthorhombic space group Pbca (No. 61) with a = 26.2799(7) Å, b = 24.1541(6) Å, c = 29.8839(6) Å, V = 18969.3(8) Å 3 , and Z = 16. Its structure contains isolated [CoSn 9 ] monocapped square antiprism and [Sn 4 ] tetrahedron in the ratio 1:2, forming a hierarchical variant of Laves phase MgZn 2 . The structural relation between the title compound with MgZn 2 as well as other binary stannides is also discussed.
