 Title    Reactions of Alkylamino-and Dialkylaminotriphenylphosphonium Halides with Halogens and Interhalogen Compounds; Formation of Alkylaminotriphenylphosphonium Polyhalides  
 Abstract    Alkylamino-and cycloalkylaminotriphenylphosphonium halides react with elemental halogens or interhalogen compounds to afford alkylamino-or cycloalkylaminotriphenyl-phosphonium trihalides. The stability of these trihalides depends on the cation as well as the trihalide anion. The assignment of a trihalide structure to these compounds was based on elemental analysis and on IR-and Raman spectroscopic evidence. Most stable are the tribromide and [1X2]° salts. During all reactions involving N-alkylamino-and N-cyclo-alkylaminotriphenylphosphonium halides and elemental halogens an N-halogenation of the cation was not observed.

 Title    One-Pot Preparation of o-Xylylene Diam ine and its Related Am ines  
 Abstract    -ich i K a w a h a ra a n d T ad afu m i U c h im a ru * D epartm ent A m ethod for one-pot preparation of o-xyly-lene diamine, 1,8-diaminomethylnaphthalene, and l,2,4,5-tetrakis(aminomethyl)benzene has been developed. The procedure is simpler and the yield of the reaction is higher than by the conven­ tional method.

 Title    Darstellung und Kristallstruktur von Cs6Cl40 P rep aratio n and Crystal S tructure of Cs6Cl40  
 Abstract    The solid state synthesis and the crystal struc­ ture of Cs6Cl40 (Pearson-code hR22, R3c, a = 1324.7(6), c -1658(1) pm, Z -6, 931 reflections with I0 > 2a(I), R\ = 0.040, wR2 = 0.114) are repor­ ted. The compound crystallises isotypically with Rb6Cl40 in the anti-K4CdCl6 type of structure. The structure consists of infinite chains of alterna­ ting face-sharing OCs6 octahedra and ClCs6 trigo­ nal prisms which are separated by chloride anions. The underlying structural concept and the ana­ logy to perovskites are outlined.

 Title    Secondary Bonding Interactions in Some Halopyridinium and Dihalopyridinium Halides  
 Abstract    The packing motifs of 2-and 3-chloropyridinium chloride can be interpreted in terms of classical hydrogen bonds N+-H -C 1~ and non-classical C-H--C1" interactions, with halo-gen-halogen contacts playing a subordinate role. In the corresponding bromine derivatives, Br--Br interactions are much more important. Of the dihalo derivatives, 3,5-dichloropyridinium chloride crystallises with classical linear hydrogen bonds of the form N+-H -C1_ , but its chlorine-chlorine interactions are at best weak; the corresponding bromine derivative displays aggregates of bromine atoms and three-centre hydrogen bonds N+-H (-B r")2 .

 Title    Darstellung und Kristallstruktur von Cs3C10 Preparation and Crystal Structure of Cs3C10  
 Abstract    The preparation and crystal structure of Cs3C10 (a = 9,442(6), b = 4,452(2), c = 16,344(10) A) is reported. In contrast to other compounds M3X O (M = alkali metal; X = halide, auride) Cs3C10 does not crystalize as an anti perovskite or a related structure, but in the a/?r/-NH4CdCl3 type of structure.

 Title    Synthese, Struktur und Reaktivität von Aminomethylpyridin- zinkdihalogeniden Synthesis, Structure and R eactivity o f A m inom ethylpyridine Zinc D ihalides  
 Abstract    Zinc dichloride reacts with aminomethylpyridine (AMP) to the corresponding 1:1 adduct 1, whereas ZnBr2 forms an ionic 1:2 complex of the type [(AMP)2ZnBr]+ Br~ 2, which loses one neutral coligand upon heating in M e-C (0)0E t to yield nearly insoluble (AM P)ZnBr2 3. The condensation reaction of these compounds with acetone yields propylideneaminomethylpyri-dine zinc dichloride (4) and dibromide (5), respectively. The reaction of Z nl2 with AMP and acetone gives propylideneaminomethylpyridine zinc dichloride (6) in quantitative yield. The structures of 3, 4, and 6 confirm the linear relationship between the Zn-N distance and the X-Zn-X angle in compounds of the type (L2)ZnX2 with L2 being a bidentate amino base, whereas short Zn-N bonds enforce small X-Zn-X angles. Compound 2 consists of separated ions in the solid state with a five coordinate zinc atom in a distorted trigonal bipyramidal coordination sphere.

 Abstract    [Er14(C2)2(N)2]l24 (triclinic, P I, a = 966.3(4) pm. b = 1027.6(2) pm. c = 1663.4(4) pm, « = 101.374(9)°, ß = 92.853(14)°, y = 112.83(2)°, Z = 2) is obtained as red-brown single crystals through a conproportionation reaction of E rl3 and erbium in the presence of carbon and N aN 3 in a sealed niobium container. It contains discrete, tetrameric [Er14(C2)2(N)2] clusters that are built from two octahedra and two tetrahedra connected via com ­ mon edges. The octahedral voids are filled with C2 units and the tetrahedral voids with N atoms. Each discrete [Erj4(C2)2(N)2] cluster is surroun­ ded by 32 iodide ligands which connect six clu­ sters via i-a and a-a bridges.
