	Title	New Metal-Rich Compounds NblrSi, NblrGe, and TalrSi -Synthesis, Structure, and Magnetic Properties
	Abstract	The metal-rich intermetallic compounds NblrSi, NblrGe, and TalrSi were synthesized by arc-melting of the elements and subsequent annealing in glassy carbon crucibles in a high-fre-quency furnace. The three compounds were investigated by X-ray diffraction on powders and single crystals: TiNiSi type, Pnma, a = 641.27(3), b = 379.48(2), c = 727.70(3) pm, wR2 = 0.0773, 430 F 2 values for NblrSi, a = 645.48(3), b = 389.21(2), c = 741.11(4) pm, wR2 = 0.0981, 297 F 2 values for NblrGe, and a = 638.11(3), b = 378.69(2), c = 726.78(3) pm, wR2 = 0.0887, 290 F 2 values for TalrSi with 20 variables for each refinement. The iridium and silicon (germanium) atoms form a three-dimensional network of puckered IrjSi3 and Ir3Ge3 hexagons in which the niobium (tantalum) atoms fill larger cages. Magnetic susceptibility measurements on NblrSi and TalrSi indicate Pauli paramagnetism with room temperature susceptibilities of 0.30(5)-10~9 and 0.97(5)-10-9 m3/mol, respectively.

	Title	Synthesis, Structure, and Magnetic Properties of EuAgCd and YbAgCd
	Abstract	New intermetallic compounds EuAgCd and YbAgCd were synthesized in quantitative yield by reaction of the elements in sealed tantalum tubes in a high-frequency furnace. Both com pounds were investigated by X-ray diffraction on powders and single crystals: KHg2 type, Imma, a = 490.41(8), b = 771.0(1), c = 834.4(2) pm, wR2 = 0.0624, 255 F values, 12 variables for EuAgCd, and MgZn2 type, Pb^/mmc, a = 584.66(5), c = 946.83(9) pm, wR2 = 0.0502, 187 F 2 values, 11 variables for YbAgCd. Owing to the very small difference in scattering power, no long range ordering of the silver and cadmium atoms is evident from the X-ray data, although Ag-Cd ordering is expected. The silver and cadmium atoms randomly occupy the mercury and zinc positions of the KHg2 and MgZn2 type structures, respectively. In EuAgCd the [AgCd] substructure consists of strongly puckered, orthorhombically distorted Ag3 Cd3 hexagons, while a three-dimensional network of face-and comer-sharing tetrahedra is observed in YbAgCd. The rare earth atoms fill the space between the Ag3 Cd3 hexagons (EuAgCd) or within the three-dimensional tetrahedral network (YbAgCd). Magnetic susceptibility measurements in dicate Pauli paramagnetism for YbAgCd and Curie-Weiss behavior above 60 K for EuAgCd with an experimental magnetic moment of 7.82(3) /j b/Eu indicating divalent ytterbium and europium. Ferromagnetic ordering at Tc = 28.0(5) K is observed for EuAgCd. At 2 K and 5 T the saturation magnetization is 5.85(5) /iß/Eu.

	Abstract	The magnetic properties of the title compound were re-investigated, since a new phase below 240 K has recently been identified. The exchange parameters were evaluated from the temperature dependence of the magnetic susceptibility with a Heisenberg operator taking into account the high pseudo-symmetry of the tetrameric units observed.

	Abstract	The preparation and structural characterization of phosphinomethylthioethernickel(II) complexes of the general type [NiX2(Ph2PCH2SR)2] (X = CI, Br, I, NCS: R = Me, Ph) are reported. In all the complexes the phosphinomethylthioethers act as monodentate ligands coordinating via the phosphorus atom. The isothiocyanate complexes are diamagnetic both in solution and in the solid state and have been assigned trans-planar configuration. As shown by magnetic measurements and by electronic spectroscopy, the halo complexes exhibit a square-planar (diamagnetic) ^ distorted-tetrahedral (paramagnetic) equilibrium in solution, while in the solid state the complexes are either square-planar or distorted-tetrahedral. For the complex [NiBr2(Ph2PCH2SMe)2] both isomers have been isolated in the solid state.

	Abstract	To characterize nickel catalysts the capability for the hydrogenation and desulfurization under standard conditions is investigated. Depending on the conditions for the preparation the catalysts are subdivided in four classes: Raney-nickel-type, two types of nickel support catalysts and nickel-Al 2 0 3 -borides. Table I shows the rates of the hydrogenation of sodium cinnamate and the values for the desulfurization of diphenylsulfide, carbondisulfide and sodiumthiosulfate. The values for the specific surface, for the volume of the pores and for the adsorption energies are determined (Table II). ESCA-measurements give an orienting impression on the composition of the surface of some selected catalysts (Table III). Table IV contains some analytical values for the nickel-Al 2 0 3 -borides. The capability for the magnetizability of some catalysts before and after the desulfurization is registrated qualitatively.

	Title	Structure and Magnetic Properties of a Dinuclear Complex with Iron(III) in Octahedral and Pyramidal Coordination
	Abstract	[FeL(M eO H)C l]2 (L = N-(2-hydroxyphenyl)salicylaldimine) was synthesized and its crystal structure determ ined, [C27H 20N 2O5Cl2Fe2], monoclinic, space group P 2 a/c, a = 9.528(1), b = 7.684(1), c = 18.365(2) Ä , ß = 109.83(1)°, V = 1264.8 Ä 3, Z = 2. Two identical [FeL(M eOH)Cl] fragments, related by an inversion centre, are combined by the two bridging O atoms, to form a binuclear unit. The iron(III) centers are separated by 3.163(2) A and weakly antiferro-magnetically coupled (J = -8 .0 (1) cm -1), which follows from temperature -dependent mag netic susceptibility m easurements in the range 4.2 to 288 K. The effective magnetic moment per iron(III) is /ueff = 7.4 /uB at 288 K.

	Title	Preparation, Properties, and Structure of the Polyphosphides VM4P16, NbNi4P16, and WNi4P16
	Abstract	The title compounds were prepared by reacting powders of the binary transition metal alloys with phosphorus in a tin melt. They crystallize with a monoclinic structure of space group C 2/c, which was determined from single-crystal X-ray data; VNi4P16: a = 1956.0(3), b = 565.9(1), c = 1106.6(2) pm, ß = 100.99(1)°, R -0.020 for 1904 structure factors and 97 variable parameters; NbNi4P16: a = 1973.0(3), b = 571.2(3), c = 1117.2(2) pm, ß = 100.74(1)°, R = 0.023 for 2431 F-values and 97 variables; WNi4P16: a = 1964.2(3), b = 568.3(2), c = 1109.3(2) pm,/? = 101.04(2)°, R = 0.031 for 371 F-values and 43 variables. The T atoms (T = V, Nb, W) have eight P neighbors, which form a slightly distorted square antiprism, and the Ni atoms have appro ximately octahedral P coordination. The P atoms form novel P8 units, which consist of 6 -mem-bered rings with a P2 side chain. Chemical bonding is discussed on the basis of classical two-electron bonds. A comparison of the interatomic distances suggests that the Fermi level cuts through a band formed by antibonding nickel-phosphorus states. A band structure is propos ed, which also rationalizes the metallic conductivity and the Pauli paramagnetism of the com pounds.

	Title	Preparation, Crystal Structure, and Properties of the Lanthanoid Carbides Ln4C7 with Ln = Ho, Er, Tm, and Lu
	Abstract	The isotypic carbides Ln4C7 (Ln = Ho, Er, Tm, Lu) were prepared by arc-melting of the elemental components, followed by annealing at 1300 °C. The positions of the metal and of some carbon atoms of the monoclinic crystal structure of LU4C7 were determined from X-ray powder data, and the last carbon positions were found and refined from neutron powder diffraction data: P2,/c, a = 360.4(1), b = 1351.4(3), c = 629.0(2) pm, ß = 104.97(2)°, Z = 2, R = 0.026 for 429 structure factors and 15 positional parameters. The structure contains isolated carbon atoms with octahedral lutetium coordination and linear Cvunits, with C-C bond lengths of 132(1) and 135(1) pm. This carbide may therefore be considered as derived from methane and propadiene. The hydrolysis of LU4C7 with distilled water yields mainly methane and propine, while the hydrolyses of the corresponding holmium and erbium carbides resulted in relatively large amounts of saturated and unsaturated C2-hydrocarbons in addition to the expected products methane and propine. The structure comprises two-dimensionally infinite NaCl-type building elements, which are separated by the C3-units. It may be described as a stacking variant of a previously reported structure of H04C7, now designated as the a-modification. The Lu4C7-type /^-modification was obtained at higher temperatures. Its structure was refined by the Rietveld method from X-ray powder data to a residual R = 0.037 for 320 F values and 15 positional parameters. Lu4C7 is Pauli paramagnetic; /3-H04C7 and Er4C7 show Curie-Weiss behavior with magnetic ordering temperatures of less than 20 K.

	Title	Er5Re2C7, Tm5Re2C7, and Lu5Re2C7 with Sc5Re2C7 Type, and Yb2ReC2 with Pr2ReC2 Type Structures
	Abstract	ErsReiCy, TmsRe2C7, and LusReaC? were prepared by arc-melting of the elemental compo nents and subsequent annealing at 800 °C. ErsRe^Cy forms only after the annealing process, whereas the other two carbides were already present in the as cast samples. They crystallize with a ScsReiC? type structure, which was refined from single-crystal X-ray data of LusRe2C7: Cmmm, a = 791.44(5), b = 1418.08(8), c = 332.79(2) pm, Z = 2, R = 0.037 for 544 structure factors and 21 variable parameters. The structure contains linear centrosymmetric C3 units with a C-C bond length of 133(2) pm and isolated carbon atoms in octahedral coordination of four lutetium and two rhenium atoms. The rhenium atoms within the two-dimensionally infinite polymeric sheets [ReiC-tln are electronically saturated as is indicated by the diamagnetism and the semiconductivity of this carbide. Yf>2ReC2 was prepared by reacting the elements in a sealed tantalum tube with a high-frequency furnace. It crystallizes with a Pr2ReC2 type structure: Pnma, a = 645.91(6), b = 498.64(6), and c = 966.05(6) pm. Magnetic susceptibility measurements indicate the ytterbium atoms to be trivalent in this compound.
