“…Biltz and Messerknecht found adducts of BeCl 2 with two, four, six, and twelve molecules of ammonia in tensieudiometric measurements. [51] Investigations of solutions of beryllium fluoride in ammonia and the adducts of these components have been conducted even more rarely as their solubility was said to be very low. [52] Biltz and Rahlfs reported the formation of BeF 2 ·NH 3 from BeF 2 and liquid ammonia, whereas Grigor' ev et al reported a product formulated as [BeA C H T U N G T R E N N U N G (NH 3 ) 4 ]- 4 ].…”

The first structural characterization of the text-book tetraammineberyllium(II) cation [Be(NH(3))(4)](2+), obtained in the compounds [Be(NH(3))(4)](2)Cl(4)⋅17NH(3) and [Be(NH(3))(4)]Cl(2), is reported. Through NMR spectroscopic and quantum chemical studies, its hydrolysis products in liquid ammonia were identified. These are the dinuclear [Be(2)(μ-OH)(NH(3))(6)](3+) and the cyclic [Be(2)(μ-OH)(2)(NH(3))(4)](2+) and [Be(3)(μ-OH)(3)(NH(3))(6)](3+) cations. The latter species was isolated as the compound [Be(3)(μ-OH)(3)(NH(3))(6)]Cl(3)⋅7NH(3). NMR analysis of solutions of BeF(2) in liquid ammonia showed that the [BeF(2)(NH(3))(2)] molecule was the only dissolved species. It acts as a strong fluoride-ion acceptor and forms the [BeF(3)(NH(3))](-) anion in the compound [N(2)H(7)][BeF(3)(NH(3))]. The compounds presented herein were characterized by single-crystal X-ray structure analysis, (9)Be, (17)O, and (19)F NMR, IR, and Raman spectroscopy, deuteration studies, and quantum chemical calculations. The extension of beryllium chemistry to the ammine system shows similarities but also decisive differences to the aquo system.

Treatment of BeCl 2 with dry liquid ND 3 and subsequent removal of the solvent leads to the colourless microcrystalline powder of [Be(ND 3 ) 4 ]Cl 2 . It crystallises in the orthorhombic space group Pna2 1 with a = 9.395(4), b = 11.901(6), c = 6.761(3) Å, V = 755.9(6) and Z = 4 at 27°C, and a = 9.3736(8), b = 11.8162(12), c = 6.6596(6) Å, V = 737.62(12) and Z = 4 at -269.6°C. The structure contains the tetrahedral tetraammineberyllium(II) cation which follows the octet rule. It was shown to be stable under ambient conditions and temperatures up to approximately 175°C. We additionally discuss the aid of solid-state quantum chemical calculations for
