AbstractFour solvent complexes of beryllium iodide were prepared by dissolving BeI2 in N,N-dimethyl formamide (DMF), pyridine (Pyr), N-methyl pyrrolidone (NMP) and 2,6-dimethyl pyridine (2,6-lutidine, Lut). Their crystal structures were established from single crystal X-ray diffraction. For [Be(DMF)4]I2 a new modification is reported (monoclinic, space group P21/c, a = 12.491(2), b = 11.593(2), c = 15.310(3) Å, β = 94.7073(6)°). In [Be(Pyr)4]I2 (monoclinic, space group C2/c, a = 17.8799(13), b = 7.6174(5), c = 18.2611(14) Å, β = 113.508(4)°) and [Be(NMP)4]I2 (orthorhombic, space group Pbca, a = 13.941(5), b = 15.754(3), c = 24.634(7) Å) homoleptic tetrahedral complex cations are formed, while the sterically demanding solvent ligand Lut yields a neutral complex with covalently bound iodine ligands [BeI2(Lut)2] (monoclinic, space group P21/c, a = 7.8492(9), b = 24.265(3), c = 27.037(3) Å, β = 97.076(3)°). Their electrochemical stability with respect to their application as beryllium electrolytes for deposition of beryllium from solution is discussed.

Sterically Demanding

The lithium amide [3,5-Me2PhN(Ad)]Li•Et2O (L) reacts with ZrCl4(THF)2 to give ZrClL3. Reactions of ZrClL3 with MeLi and NaBH4 produce the corresponding ZrMeL3 (2) and Zr(BH4)L3 (3), respectively. The molecular structures of 2 and 3 were determined by X-ray crystallography. Crystal data are as follows. 2: C55H75N3Zr, FW 869.45, orthorhombic, Pcab; a = 19.2436(3) Å,b = 45.9342(4) Å, c = 21.2935(3) Å, V = 18822.2(4) Å3Z = 8; 3: C54H76BN3Zr, FW 869.25, orthorhombic; Pbc21, a = 11.5399(3) Å,b = 19.4091(4) Å, c = 20.4471(5) Å,V = 4579.72(19) Å3Z = 4.
