Structure D 2000Tetracyanoborate Salts M[B(CN) 4 ] with M = Singly Charged Cations: Properties and Structures. -The single crystal X-ray structures, vibrational spectra, solubilities in water, and thermal stabilities of (III), (V), and (VIII) are determined and compared with already known M[B(CN)4] salts. (Ib) crystallizes in the cubic space group Fd3m with Z = 8, (IIIa) and (VIII) in the cubic space group P43m with Z = 1, (IIIb), (V), Cs[B(CN) 4 ], and NH 4 [B(CN) 4 ] in the tetragonal space group I4 1 /a with Z = 4, and the THF adducts Na[B(CN)4]·THF and NH4[B(CN)4]·THF in the orthorhombic space group Pnma with Z = 4. The latter two phases are not isostructural. The cubic structures of the Li + , Na + , and Cu + salts consist of two interpenetrating independent tetrahedral networks of M + cations and [B(CN)4]ions. In the vibrational spectra the two CN stretching modes A 1 and T 2 coincide in general and the band positions are a measure for the strength of the interionic interaction. An interesting feature in the Raman spectrum of the copper salt is the first appearance of two CN stretching modes. -(KUEPPERS, T.; BERNHARDT, E.; WILLNER*, H.; ROHM, H. W.; KOECKERLING, M.; Inorg.

II (DMF)6][B(CN)4]2. -The single crystal X-ray structures, thermochemical properties, electrochemical characteristics, and vibrational spectra of (III), the coordination polymer [Fe II (H2O)2{κ 2 N[B(CN)4]}2] (V), and (VI) are given. (III) is the first tetracyanidoborate with a triply charged metal cation. It crystallizes in the rhombohedral space group R3 with Z = 6. Compound (V) crystallizes in the tetragonal space group I42d with Z = 4, and (VI) in the triclinic space group P1 with Z = 1. Compounds (III) and (VI) contain isolated complex ions, whereas (V) comprises a coordination polymer, in which the Fe II ion is coordinated by two oxygen atoms of two water molecules in a trans orientation and four nitrogen donor atoms of the [B(CN) 4 ]groups, which bridge between neighboring iron ions. -(NITSCHKE, C.; KOECKERLING*, M.; Inorg.

Crystals of two groups of the new title compounds, which differ in their amount of coordinated and crystallized water molecules are obtained after evaporation of the solvent. [Tb(H2O)8][B(CN)4]3·2.58H2O, [Dy(H2O)8][B(CN)4]3·2.53H2O, and [Y(H 2O)8][B(CN)4]3·2.32H2O crystallize in the monoclinic space group C2/c with Z = 8. After crystallization, a slow structure reorganization with the loss of water molecules finally forms compounds (IVa-h). (IVg) crystalllizes in the monoclinic space group P21/n with Z = 8. The crystal structures are determined by single crystal XRD. Both structures exhibit discrete eight-coordinated Ln 3+ complex cations, as [Ln(H 2O)8] 3+ and [Ln(H2O)7{ 1 N-B(CN)4}] 2+ . Compounds (IVa) and (IVb) show intense green and yellow emission upon excitation at 254 nm. -(FALK, F.; HACKBARTH, L.; LOCHBRUNNER, S.; MARCINIAK, H.; KOECKERLING*, M.; Eur. J. Inorg.
