Synthese und Kristallstrukturbestimmung von Cs([18]Krone-6)Au · 8NH3/ Synthesis and Crystal Structure Determination of Cs([18]crown-6)Au· 8NH3

Cs([18]crown-6)Au ・ 8NH3 was synthesized from CsAu and [18]crown-6 in liquid ammonia. The extremely air- and temperature-sensitive colorless, block-shaped crystals were analyzed by single crystal X-ray diffractometry. The compound forms triclinic crystals of space group P1 (no. 1) with a = 8.765(2), b = 11.186(2), c = 13.997(3) Å , α = 86.180(6), β = 89.669(6), γ = 83.774(6)°, V = 1361.2(4) Å3. The crystal structure consists of ammonia nets extending perpendicular to [110] in which the Cs([18]crown-6) fragments and the auride anions are embedded
