Triphenyltelluronium hexachloroplatinate (1), hexachloroiridate (2), tetrachloroaurate (3), and tetrachloroplatinate (4) were prepared from Ph 3 TeCl and potassium salts of the corresponding anions. Upon recrystallization of 4 from concentrated nitric acid, K 2 [PtCl 6 ] and (Ph 3 Te)(NO 3 ).HNO 3 (5) were obtained. The crystal structures of 1-3 and 5 are reported. Compounds 1 and 2 are isostructural. They are triclinic, P1, Z=2 (the asymmetric unit contains two formula units). Compound 1: a=10.7535(2), b=17.2060(1), c=21.4700(3) Å, α=78.9731(7), β=77.8650(4), γ=78.8369(4) o . Compound 2: a=10.7484(2), b=17.1955(2), c=21.4744(2) Å, α=78.834(1), β=77.649(1), γ=78.781(1) o . Compound 3 is monoclinic, P2 1 /c, Z=4, a=8.432(2), b=14.037(3), c=17.306(3) Å, β=93.70(3) o . Compound 5 is monoclinic. P2 1 /n, Z=4, a=9.572(2), b=14.050(3), c=13.556(3) Å, β=90.76(3) o . The primary bonding in the Ph 3 Te + cation in each salt is a trigonal AX 3 E pyramid with Te C bond lengths in the range 2.095(8)-2.14(2) Å and the bond angles 94.1(6)-100.9(5) o . The weak Te...Cl (1-3) and Te...O (5) secondary interactions expand the coordination sphere. In 1 and 2 the cation shows a trigonal bipyramidal AX 3 YE coordination with one primary Te C bond and the shortest secondary Te...Cl contact in axial positions and the two other Te C bonds and the lone-pair in equatorial positions. The cation in 3 shows a distorted octahedral AX 3 Y 3 E environment and that in 5 is a more complex AX 3 Y 3 Y' 2 arrangement. In both latter salts the structure is a complicated three-dimensional network of cations and anions.
