Abstract

The three new compounds crystallize orthorhombically, space group Cmcm with Na₂AuAs: a = 887.1(2) pm, b = 712.9(2) pm, c = 576.0(2) pm;

Na₂AuSb: a = 927.9(3) pm, b = 756.2(2) pm, c = 584.1(5) pm;

K₂AuSb: a = 1045.9(5) pm, b = 786.1(3) pm, c = 650.0(5) pm.

The structure of Na₂AuAs and Na₂AuSb contains Au-As(Sb) zigzag chains in which the Au atoms are linearly bonded to the 5b-elements. The powderdiagram shows the phase K₂AuSb to be isotypic to Na₂AuAs and Na₂AuSb.
