Die Kristallstruktur von [Mg(H2O)6](N3)2 / The Crystal Structure of [Mg(H2O)6](N3)2

Azido Beryllates with Adamantan‐like Structures: Synthesis, IR Spectra, and Crystal Structures of (Ph4P)2[Be4X4(μ‐N3)6] (X = Cl, Br)The azido beryllates (Ph4P)2[Be4X4(μ‐N3)6] (X = Cl 1a, X = Br 1b) have been prepared by the reaction of Me3SiN3 with the halogeno beryllates (Ph4P)2[Be2Cl6] and (Ph4P)2[Be2Br6], respectively, in CH2Cl2 and CH2Br2 solution, respectively. Both complexes form moisture sensitive, colourless crystals, which are nonexplosive with respect to mechanical or thermal stress. They are characterized by IR spectroscopy and by crystal structure determinations. 1a and 1b crystallize isotypically in the space group C2/c with 12 formula units per unit cell. Whereas 1a was only refined to R1 = 0.13, which is caused by disordering, 1b could be refined to R1 = 0.066. The structures contain adamantanlike dianions [Be4X4(μ‐N3)6]2— with two symmetry nonequivalent individuals which differ only slightly from one another. The Be4N6 core is formed by bridging function of the α‐nitrogen atoms of the azide groups with BeN bond lengths of 172.5 and bond lengths Nα—Nβ = 123.2 pm and Nβ—Nγ = 113.1 pm on average in the structure of 1b.

Dedicated to Professor Cameron Jones on the Occasion of his 60 th Birthday.Ion exchange processes are rarely investigated with respect to tetrel element Zintl clusters. We now discovered that the addition of Mg complexes to nonagermanide anions comprising K + counter cations results in an exchange of the alkali ions by alkaline earth cations. Upon stirring K[Ge 9 {Si(TMS) 3 } 3 ] (TMS = trimethylsilyl) and Mg(NacNac Mes )I (NacNac Mes = N,N '-bis(2,4,6trimethylphenyl)-β-diketiminate) in MeCN the product [Mg(NacNac Mes )(MeCN) 4 ][Ge 9 {Si(TMS) 3 } 3 ]• MeCN is formed. Reactions of Mg(NacNac Mes )I with K 4 Ge 9 in liquid ammonia as a solvent yielded [K[2.2.2]crypt] 4 [Mg(NacNac Mes )(NH 3 ) 4 ] 2 [Ge 9 À Ge 9 ] • 32.58 NH 3 featuring a mixed alkali/alkaline earth metal cationic sphere and an oxidative coupling of the [Ge 9 ] 4À clusters. From comparable reactions of [Mg(NacNac Mes )] 2 with K 4 Ge 9 or K 12 Ge 17 in liquid ammonia crystals of [K-[2.2.2]crypt][NacNac Mes ] • NH 3 and [K(18-crown-6)][NacNac Mes ] • 3 NH 3 , respectively, were isolated. All compounds were characterized by means of single crystal structure determination.
