Na 17 Ga 29 ln 12  (a = 2178.5(5) pm, Fd3m, Z = 8, R = 0.081) and K 17 In 41  (a = 2424.1(5) pm, Fd3m, Z = 8, R = 0.060) have been prepared from the elements and characterized by single crystal X -ray methods. Na 17 Ga 29 ln 12  is a ternary variant of K 17 In 41 . The crystal structure of Na 17 Ga 29 ln 12  contains Ga 12  icosahedra (In 12 icosahedra in K 17 In 41 ) and truncated In 12  tetrahedra which are four-capped and centred by additional Ga atoms (In atoms in K 17 In 41 ). The packing of icosahedra and truncated tetrahedra leads to interpenetrating Samson polyhedra. The Ga 12  icosahedra (In 12  icosahedra in K 17 In 41 ) take the Cu positions of the MgCu 2  type, the In 12  clusters take the positions of the Mg atoms of this structure type. The alkali atoms in Na 17 Ga 29 In 12  and K 17 In 41  occupy the deltahedral faces of the icosahedra and form pentagonal dodecahedra
