“…Regarding ternary beryllium halides, only 34 examples appear to be structurally characterized to date [8]. Besides the alkali metal tetrachlorido beryllates, also chloridoberyllates of Sr, Ba, Tl, Pb, Eu, and Sm have been described in the literature [3,[10][11][12][13]. Also, zirconium halide cluster phases such as BeZr 6 X 2 (X = Cl, Br), Be 2 Cl 6 Te 7 and BeCdF 4 are known and have been structurally characterized [14][15][16].…”

Reactions of zinc chloride with beryllium chloride in the molar ratios of 1:1 and 3:2 at T = 300°C in sealed ampoules lead to the formation of the two compounds Be1−xZnxCl2 (x = 0.563(2) and 0.489(3), respectively). Their composition and crystal structures were evidenced by single crystal X-ray structure analysis. Both compounds crystallize isotypic to β-BeCl2 in the tetragonal space group I41/acd, No. 142, tI96, with a = 10.7548(1), c = 19.4656(5) Å, V = 2251.50(7) Å3, Z = 32 at T = 100 K for the first and a = 10.7511(3), c = 19.2335(10) Å, V = 2223.1(2) Å3, Z = 32 at T = 100 K for the second compound. The positions of the Be atoms are mixed-occupied by Zn atoms. The compounds were additionally characterized by powder X-ray diffraction and infrared spectroscopy. Plots according to Vegard’s law allowed for extrapolation towards a neat ZnCl2 phase that would crystallize in the β-BeCl2 structure, which is the ZnI2 structure type. Quantum chemical calculations have confirmed that such a ZnCl2 modification would represent a true local minimum.

Berylliumdichlorid reagiert mit Tetraphenylphosphoniumchlorid in Dichlormethan je nach dem angewandten molaren Verhältnis unter Bildung der leicht löslichen Chloroberyllate (Ph4P)2[BeCl4]·2, 5CH2Cl2 (1·2, 5CH2Cl2) und (Ph4P)2[Be2Cl6] · 2CH2Cl2 (2·2CH2Cl2). Beide Verbindungen werden durch Kristallstrukturanalysen charakterisiert. 1·2, 5CH2Cl2: Raumgruppe P1¯, Z = 2, Gitterkonstanten bei 193 K: a = 1185, 7(1); b = 1244, 5(1); c = 1939, 3(2) pm; α = 77, 62(1)°; β = 74, 13(1)° γ = 68, 17(1)°, R1 = 0, 0416. Das [BeCl4]2‐‐Ion bildet Tetraeder ohne spezielle Lagesymmetrie. 2·2CH2Cl2: Raumgruppe P1¯, Z = 1, Gitterkonstanten bei 193 K: a = 985, 3(1); b = 1107, 6(1); c = 1344, 7(1) pm; α = 65, 45(1)°; β = 79, 12(1)°; γ = 78, 49(1)°, R1 = 0, 0361. Das [Be2Cl6]2‐‐Ion bildet chloroverbrückte Doppeltetraeder der Lagesymmetrie 1¯ (Ci). Im Vakuum verlieren die Verbindungen das eingelagerte Dichlormethan. Von 1 und 2 werden die Schwingungsspektren (IR, Raman) mitgeteilt.

Recent Advances in the Chemistry of BerylliumA review of recent results in coordination chemistry of beryllium halides is given. In accordance with the editors' objective, this Research Report is not a complete review of the literature in this field, but the important literature close to it is considered. The following subjects are presented:(i) Syntheses and structural characterizations of tetraphenylphosphonium salts of [BeCl4]2−, [Be2Cl6]2−, and the unique [Be2F6]2− ion, which are soluble in organic solvents like dichloromethane or acetonitrile. (Ph4P)2[Be2F6]·2CH3CN is also extensively studied by IR spectroscopy and quantum chemical calculations (DFT).(ii) Application of (Ph4)2[Be2Cl6] to prepare donor acceptor complexes with N‐donor ligands D to give complexes [BeCl3(D)]− which are isoelectronical with the corresponding boron compounds [BCl3(D)], including quantum chemical calculations.(iii) Molecular complexes of the type [BeCl2(D)2] with D = phosphorane imines HNPR3 or Me3SiNPR3.(iv) Phosphoraneiminato complexes of beryllium, among these the first example [BeCl(μ‐NPEt3)]4 with a Be4N4 heterocubane skeleton.(v) Azido complexes of several types, including the unique examples with adamantane‐like structure [Be4X4(μ‐N3)6]2− with X = Cl, Br.(vi) Monocationic complexes [BeCl(12‐crown‐4)]+[SbCl4]− and [BeCl(PMDETA)]+Cl− (PMDETA = pentamethyl‐diethylenetriamine).(vii) Dicationic complexes with O‐donor ligands H2O and OSMe2. [Be(OH2)4]Cl2, [Be(OSMe2)4]Cl2, and mixed ligand complexes like [Be(OH2)2(OSMe2)2]Cl2.(viii) Molecular and anionic oxo‐complexes, particularly with μ‐OSiMe3 groups, among these the tetramethyl‐trioxosilanato complex (Ph4P)2[Be4(μ‐Cl)2Cl4(OSiMe2OSiMe2O)2].
