 Title    Darstellung, Eigenschaften und elektronische Raman-Spektren von Di(bromo)phthalocyaninatometallaten(III) der Eisengruppe  
 Abstract    Synthesis, P ro p erties an d E lectronic R am an Spectra of D i(b ro m o)p h th alo cy an in ato m etalates(III) of the Iron G roup E lem ents Svend Sievertsen, H en d rik Schlehahn, H ein er H om borg Low spin di(bromo)phthalocyaninatometalates of tervalent iron, ruthenium and osmium ([MBr2Pc2-]') are formed by the reaction of [FeBrPc2~] or H[MBr2Pc2 ] (M = Ru, Os) with ex­ cess bromide in DMF or THF and isolated as ("Bu4N)+ salts. The electronic spectra show the typical J i-jr*-transitions (B, Q, N region) of the Pc2~ ligand together with a number of extra bands due to trip-multiplett and (Pc, Br — » M)CT transitions. vs(MBr) is observed in the resonance Raman (RR) spectrum (RR enhanced for M = Fe, Ru) at 161 cm-1 (Fe), 183 cm4 (Ru) and 192 cm-1 (Os), vas(MBr) at 251 cm4 (Fe), 234 cm-1 (Ru) and 218 cm-1 (Os) in the FIR spectra. The RR spectra obtained by excitation at low absorbance between the B and Q region are dominated by the intraconfigurational 'T 7 — > r 8" transition due to spin orbit split­ ting of the 2T2g ground state for Fe at 583 cm-1, Ru at 1026/1050 cm-1 and Os at 3131 cm4 . In the MIR resp. NIR spectra vibronically induced transitions are observed for the Ru or Os complex.

Hg; X = P, As, Sb). The calculated stretching force constants are: f(M n -P) = 1.89 {M11 = Zn}, 1.66 {Cd}, 1.83 {Hg} N cm -1 and f(C u -X) = 1.27 {X = P}, 0.99 {Sb} and f(A g -A s) = 0.93 N c m " 1 respectively. These are compared with those of the isoelectronic m olecules M nY 2 and [M'Y2]~ in relation to charge effects (M 11 = Zn, Cd, Hg; M 1 = Cu, Ag; Y = Cl, Br).

 Title    Kristallstruktur und Schwingungsspektren von Zn(NH 3)4(C104)2 Crystal Structure and Vibrational Spectra of Zn(N H 3)4(C104)2  
 Abstract    The title compound Z n (N H 3)4(C104)2 crystallizes in the space group F 43m with a = 10.240(1) A. The crystal structure consists of tetrahedral Z n (N H 3)4 cations and two non­ equivalent C 104 anions with crystallographic Td symmetry. The complex ions constitute an arrangement which is known from the Zintl phase M gAgAs. The Z n(N H 3)4 cations are ccp packed with perchlorate anions in octahedral and tetrahedral voids. W hereas the C 104 ions centered at tetrahedral holes do not interact with the other lattice components, the perchlo­ rate ions in the octahedral voids are connected with the ammine ligands by a hydrogen bonded three-dimensional network involving all their N, H, and O atoms. The repeating unit of this network is a N40 4(m-H)12 cube with N -H = 1.19(2)A and O -H = 1.98(2)A . Raman and IR spectra were recorded between 150 and 4000 cm -1. A ll the expected internal m odes of the com plex ions could be detected and assigned. The crystallographically different C 104 anions have nearly the same vibrational spectra, only a slight splitting o f two IR m odes is observed.

 Title    Darstellung, Schwingungsspektren und Normalkoordinatenanalyse der  
 Abstract    The IR and Raman spectra of the ten brom o-iodo-rhenates(IV) [ReBr"I6_"]2 -, n = 0 -6 , including the geometrical isomers for n -2,3,4, have been recorded at 80 K. The vibrational spectra are com pletely assigned according to point groups O h, D 4h, C4v, C3v, and C2v, as supported by normal coordinate analyses based on a general valence force field. Due to the different mms-influences Br < I in asymmetric axes B r '-R e -I ', the R e -I ' bonds are strengthened and the R e -B r ' bonds are weakened, as indicated by valence force constants, for R e -I ' on average 8,5% higher and for O s -B r ' 8,3% lower, as compared with the values calculated for symmetric I -R e -I and B r -R e -B r axes, respectively
