Abstract

‘The reaction of AuCN with Sex 2_ and Tex 2’ in dimethylformamide in the presence of organic cations forms complexes with ring structures such as (Ph4P)2[Au2Se5] (I), (Ph4P)2[Au2Se6l (II), (Ph3P N P P h3)2 – K2[Au4Te4]–2DMF (III). The reaction of AuCI3 with Te2– yielded (Ph4P)2[Au2(Te2)2l (IV). (1) crystallizes in the triclinic space group P–1 with a=10.381 (4) A, b=11.002(5) A, c=21.181(9) A, ct = 75.50(4)0, P = 74.74(3)0, y=81.40(4)0, V=2250 A3 (–93 °C). (II) crystallizes in the monoclinic space group C2/c with a=28.409(7) A, b=10.97(1) A, c=19.762(5) A, 0=130.49(1)°, V–4680 A3 (23 °C). (Ill) crystallizes in the orthorhombic space group Pbcn with a=29.90(2)A, b=17.39(2)A, c=17.707(8)A, V=9206A3 (23 °C). (IV) crystallizes in the triclinic space group P–1 with a–10.526(3)A, b=11.237(2)A, c=10.453(4)A, a=103.03(2)0, p=106.95(3)0, y=81.66(2)0, v=1148 A3 (–95 °C). Single–crystal X–ray diffraction studies of (I) and (II) show that both compounds possess the same structural feature. Two linearly–coordinated Au(i) atoms interact with each other at 3.004 A in (I) and 3.132A in (II) with a bridging Se22’ unit on one side and a bridging triselenide Se3 2– ligand (for I) and tetraselenide Se4 2– ligand (for II) on the other, forming respectively seven and eight membered rings each containing two gold atoms. The structure of (III) consists of a distorted square where the Te atoms occupy the corners and the Au atoms lie in the center of the square's edges. Ionic interactions between the Au and K atoms result in a one-dimensional structure. The structure of (IV) is similar to those of (I) and (II) except two Te22” ligands are involved.
