Abstract
Na7Ga13-II crystallizes in the orthorhombic system, space group Pnma with the constants a - 1562.5(3) pm, b = 1497.9(3) pm, c = 2167.8(4) pm. The Ga-atoms form Gaj.2 icosahedra and Gais clusters connected to a threedimensional network. The centres of these clusters correspond to the atomic positions of the MgCu2 structure. The number of bonding electrons is related to the Na content of the compoundKeywords
