 Title    Kristallstruktur und Schwingungsspektren von |( « -C 4H9)4N |2|Re2F8| * 2(C2H 5)20 Crystal Structure and Vibration Spectra of [(/z-C4H9)4N]2[Re2F 8] * 2(C2H 5)20  
 Abstract    The dark blue title compound has been prepared by reaction of [Re2Cl8]2" and F~, both dis­ solved as ion pairs with [(/z-C4H9)4N]+ in anhydrous CHUCK, and recrystallization from ace-tone/diethylether. Structure determination by single crystal _X-ray diffractometry at 150 K reveals crystallization in the cubic system, space group Pn3n with a = 19.783(3)A, V = 7742.4Ä 3, Z = 6. The {[Re2F8] • 0 (C ,H 5)2}2" entity consists of an axially elongated F8-cubane frame around the Re2 unit, which is coordinated at one side by an ether molecule (R e-O dis­ tance 2.64(4) A) and displaced from the center towards the ether. The R e-Re quadruple bond (2.188(3) A) is the shortest of the four octahalogenodirhenates(III). In contrast to its Cl. Br and I homologues no disorder of the Re2 units is observed. The R e -F distances of 1.92(3) and 1.96(3)A are equal within the standard error, and the R e -R e -F angles are 99.9(4) and 102.6(4) , respectively. The UV-Vis spectrum of [(«-C 4H 9)4N]2[Re2F J shows only the <5-<5* transition at 558 nm (e = 771 cm'/mmol). At 10 K this band exhibits a weak vibrational fine structure with an averaged progression of 209 cm-1. The Raman spectrum is dominated by v(Re-Re) at 317.5 cm 1 with up to five overtones, the IR spectrum by v(Re-F) at 560 cm-1. Additional bands for the solvated compound at 525 and 306 cm" 1 are assigned to v(Re-O) and v(Re-Re), respectively. The 19F N M R spectrum in aceton-d6 shows a singlet at -135.06 ppm; in the presence of ether an additional weak signal arises at -134.15 ppm versus external CFC1V

 Title    The Crystal Structure of IV ^SiNPPl^CF^PPl^ and NM R Investigations on its Proposed Thermal Isomerization  
 Abstract    The crystal structure of Me^SiNPPh-.CH-.PPh-, (1) has been determined in order to obtain information about the ground state conformation in the solid, and about unusual steric effects which could give rise to conformational isomers. It was recently proposed that such isomers exist due to restricted rotation about the P = N bond, and are generated by heating the com­ pound to 160 C. The evidence for them was based on the observation of multiple N M R sig­ nals in CDClj solutions of samples which had been so treated. The crystal structure yields a P -N -S i bond angle of 150.2(2) , a P -N bond length of 1.529(3) A and a S i-N bond lengths of 1.668(3) A. It is clear that, as a result of the relatively large P -N -S i angle in 1, there is no steric hindrance to rotation about the P -N bond in this molecule. Attempts to study the ener­ getics of the proposed isomerization by recording the N M R spectra of heated samples showed that the previously reported multiple N M R signals are not generated in this way. However, such signals are generated at ambient temperature under various circumstances, for example in the course of the reaction of a CDC13 solution of 1 with methanol to produce HNPPh-,CH2PPh2 (2). The observation that it is not necessary to heat 1 in order to generate these signals makes their assignment to rotational isomers rather less likely. In the absence of a reproducible method of producing these signals in a pure sample, the existence of such isomers should be regarded as not yet proven.

 Title    Darstellung und spektroskopische Charakterisierung von Nitridophthalocyaninatomangan(V) Preparation and Spectroscopical Characterization of Nitridophthalocyaninatom anganese(V)  
 Abstract    Nitridophthalocyaninatomanganese(V), M nN Pc(2-), has been prepared by oxidation of [Mn(OH):Pc(2-)]~ with chlorine in the presence of excess ammonia in dichloromethane as a chemically very stable, diamagnetic microcrystalline blue powder. The band at 1053 cm 1 in the infrared and resonance Raman spectra is assigned to v(Mn=N). The strong resonance en­ hancement of v(Mn=N) coincides with an electronic transition at 461 nm assigned to (N —> Mn) electron transfer. The UV-VIS spectrum in 1-chloronaphthalene is compared with that of the M nN Pc(2-)-H -,S04 adduct and the phthalocyanine-7r-cation radical [MnNPc(l -) ] +.

Their structures have been determined: Crystal data, 2, monoclinic, space group C2/c, a = 1914.5(6), b = 823.0(1), c = 1669.5(5) pm, ß = 133.23(1)°, Z = 4; 1809 reflections, R = 0.024. 3, triclinic, a = 779.2(3), b = 958.7(4), c = 1478.8(4) pm, a = 82.34(3), ß = 82.68(2), y = 73.47(3)°, Z = 1; 3376 reflections, R = 0.045. 2 contains infinite chains of centrosymmetrical [Cu(en)2]2+ cations and bisphenoidal [Cu(C40-,S2)-,]2" anions. 2 shows ferromagnetic behaviour above 75 K. At lower temperatures antiferromagnetic coupling between the chains dominates. 3 contains isolated [Co(en)2H 20 ]2+ cations and tetrameric [Cu(C40-,S2)]~ anions. The anion consists of a chain of tetrahedrally and trigonally coordinated Cu(I) atoms with short Cu-■ • Cu distances of 255.2(1) and 257.9(1) pm. The dithiosquarate ligands are stacked in pairs.
