摘要

Silver coloured, brittle single crystals of NaAuIn2 were synthesized by the reaction of NaN3, gold-sponge and indium at 500 degrees C. The structure was determined from X-ray single-crystal diffractometry data: space group Cmcm, Z = 4, a = 4.482(1) Angstrom, b = 10.366(2) Angstrom, c = 7.869(2) Angstrom, R/R(w) (w = 1) = 0.017/0.020, Z(F-o(z)) greater than or equal to 3 sigma (F-o(2)) = 547 and N(var.) = 16. NaAuIn2 crystallizes in the MgCuAl2-structure type. Gold and indium form a framework structure. (2)(infinity)AuIn6/3 layers with trigonal prismatically coordinated gold are connected via In-In contacts along 010 which consist of ethane analogous In2Au6-building units. The In-partial structure consists of saw tooth like (1)(infinity)In-2/2 chains along 001. The sodium atoms occupy channel-like cavities within the Au-In framework structure. References: 21
