Complexes [XLiL3], X = Cl , Br, I; L = 4-t-butylpyridine, (1)-(3) have been synthesized by recrystallization of the anhydrous lithium halide from the parent base, and characterized structurally by single-crystal X-ray structure determination. (1) and (2) are isomorphous (monoclinic, P21), a ≈ 11.8, b ≈ 12.1, c ≈ 11.8 Ǻ, β 120°, Z 2 (R 0.051, 0.040 for No 1491, 1499 'observed' reflections); (3) is orthorhombic, Pbca, a 22.119(10), b 21.108(10), c 12.845(10) Ǻ, Z 8, R 0.067 for No 967. (1)- (3) are all pseudo- trigonal and contain four-coordinate XLiN3 arrays [Li-X, 2.33(1); 2.53(1); 2.76(4) Ǻ; Li-N, 2.03(1)-2.11(1); 2.04(1)-2.09(2); 2.03(4)-2.07(4)Ǻ]. Similar data are also recorded for X = I, L = quinoline (4)[monoclinic, P21/c, a 15.684(6), b 7.693(4), c 26.758(12) Ǻ,β 107.71(3)°, Z 4; R 0.072, No 3096; Li-I, 2.78(2); Li-N, 2.08(2)- 2.13(2)Ǻ].

K3BiO3 and Rb3BiO3 have been synthesized for the first time by solid state reactions of the respective binary compounds. K3BiO3 was obtained from Bi2O3 and K2O at 550 °C, Rb3BiO3 from Bi2O3 and Rb2O at 650 °C. The compounds were structurally examined by single-crystal X -ray investigations (K3BiO3: I 4̅ 3 m, a = 1070.15(2) pm, Z = 8; Rb3BiO3: P 21 3, a = 875.48(2) pm, Z = 4). The structures reveal “isolated” BiO33- groups. While K3BiO3 is isostructural to Na3BiO3, Rb3BiO3 has the same crystal structure as Cs3BiO3.

By reaction of (n-Bu4N)2[ReBr6] with pyridine and (n-Bu4N)BH4 in dichloromethane various bromo-pyridine-rhenium(III) complexes are formed which can be separated by chromatography. Electrochemical oxidation of (n-Bu4N)2[ReBr5Py] leads to (n-Bu4N)[ReBr5Py]. X-ray structure determination on a single crystal has been performed of (n-Bu4N)[ReBr5Py] (monoclinic, space group P21/n a = 11,248(5), b = 17,192(5), c = 15,206(5) Å, β = 97,600(5)°, Z = 4).

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
