Abstract
Investigating the system MF4/AuF3 (M = Th4+ Ce4+) we obtained unexpectively Au[AUF(4)](2) in form of irregular, brown single crystals. It crystallizes monoclinic, space group P2(1)/n (No. 14) with a = 527.21(7) pm, b = 1070.7 6(10) pm, c = 573.45(7) pm, beta = 90.633(14)degrees, Z = 2, isotypic with Ag[AuF4](2) and Pd[AuF4](2). As a further by-product we obtained for the fi rst time colourless single crystals of CeF4 (monoclinic, C2/c, No.15, a = 1 258.83(8) pm, b=1062.63(8) pm, c = 822.41(9) pm, beta = 126.24(1)degrees, a nd Z = 12).
