	Title	Zur Darstellung und Struktur von CaMnBi 2 On the Preparation and Crystal Structure of CaMnBi2
	Abstract	The new compound CaMnBi2 has been analytically and structurally characterized. CaMnBi2 crystallizes in the tetragonal system (a — 450 ^ 1 pm, c = 1108 ± 2 pm, space group P4/nmm). Mn and Bi atoms form fourfold pyramids, connected by common edges in the basis to two-dimensional sheets. These sheets are separated by double layers of Ca atoms between which further Bi atoms are located forming squarenets. The structure is strongly related to that of SrZnSb2 which can be interpreted as a distorted variant of the new CaMnBi 2 type.

	Title	B. Krebs-D. Sinram * Darstellung, Struktur und Eigenschaften einer neuen Modifikation von Nbls 20 Preparation, Structure and Properties of a New Modification of Nbls
	Abstract	Triclinic niobium(V) iodide was prepared from the elements at an iodine pressure of 3-4 bar in a temperature gradient from 400 to 230 °C. It crystallizes in the space group PI with a = 7.591(3), b = 10,322(3), c = 6.977(3) A, a = 90.93(3), ß = 116.17(3), y = 109.07(3)°, Z = 2 Nbls. The single-crystal X-ray structure analysis shows the compound to contain dimeric Nb2lio molecules with Nb-I bond lengths of 2.933 and 2.939(1) A for the bridge bonds and of 2.639 • • • 2.720(1) A for the terminal bonds. The structure is isotypic with triclinic /S-UCI5. The infrared spectrum indicates stretching vibrations at 148, 202, 214 and 242 cm-1 .

	Abstract	The crystal and molecular structure of the compound Sn3(NC(CH3)3)4H2 has been determined from X-ray data (R = 0.044). The crystals are cubic, space group Pa3, with cell dimension a — 1713.6(8) pm and Z = 8. The molecules, which have a seco-norcubane like Sn3N4 framework, are statistically disordered, thus forming closed packed pairs of molecules. The Sn3N4 cage deviates strongly from a cube, the bond angles at Sn approach-ing 80°, and at N 100°. The averaged Sn-N bond distance is 223(1) pm.

	Title	The Topochemical Reaction of CaSi2 to a Two-Dimensional Subsiliceous Acid Si6H3(OH)3 (= Kautskys' Siloxene)
	Abstract	Kautsky's siloxene was prepared in a topochemical reaction from large crystals of CaSi2. The structure model was revised. Siloxene is a subsiliceous acid [Sie]H3(OH)3 and consists of two-dimensional corrugated Si-layers with three Si-Si bonds per silicon and an OH-or H-ligand, respectively. Ordering of adjacent layers is turbostratic. The layer lattice is capable of forming intercalation complexes. On intercalation only the layer distance is changed. The alkoxylated derivatives Si6H3(OCH3)3" and Si6H3(OC2H5)3" are also able to inter-calate polar molecules.

	Title	Die Isopolymolybdationen in wäßrigen Medien im Bereich Z < 1,14 Concerning Isopolymolybdate Ions in Aqueous Media in the Range Z < 1.14
	Abstract	The system H+/Mo04 2_ was investigated by Raman spectroscopy in the range Z = 0 to 1.14 at initial concentrations Cmo042-= 0.02 to 2M and concentrations of the ionic medium CMe+ = 2CMOO42-to 3 M Me(Cl,NOg) (Me = Li, Na, K,NH4, Mg/2). The mole-ratio method and intensity difference diagrams do not indicate any species between Mo04 2-and M07O24 6 "" contrary to propositions in recent papers. A detailed evaluation of the extensive data shows the possible portion of such species to be <3%, this value having a statistical certainty of 95%. Comparing the solutions having Z = 1.1 by fingerprint procedures, in all cases Mo7024 6_ is the first main product (detectable by static methods) irrespective of the nature and concentration of the ionic medium. Thus, Mg 2+ ions do not influence the course of aggregation of molybdate ions as has been proposed in the literature. This is in accord-ance with theoretical investigations since the Mo7024 6_ ion has the distinction of a number of favourable structural parameters in the system that become operative in case of scarcity of H+ ions.

	Abstract	TiCU reacts with trimethylsilyl difluorophosphate (Me3SiP02F2) and with trimethylsilyl dimethylphosphinate (Me3SiP02Me2) at room temperature under cleavage of the Si-0 bond to give the principal products Cl2Ti(P02F2)2 and Cl2Ti(P02Me2)2, respectively. The former product has also been obtained from the reaction of P2O3F4 with TiCU-SbCls is capable of cleaving the P-0 bond in P2O3F4 to give Cl4SbP02F2, but forms addition compounds with Me3SiPC>2F2 and Me3SiPC>2Me2 in which the terminal oxygen atoms of the esters are bound to antimony. IR spectra have been used to elucidate the structures of the prepared compounds.

The magnetic moments and the EPR spectra of the complexes and the free radicals have been investigated and compared with complexes containing diamagnetic cyclohexanecarboxylic acid or cyclo -hexaneacetic acid ligands. One of the copper(II) complexes shows a considerable inter-action between the nitroxyl radicals of the ligands.

	Abstract	The lithiumphosphido complex cis-Mo(CO)4(Me2PLi)2 reacts with dichlorophosphines RPCI2 (R = Ph, Bu') to give coordination compounds of tetraphosphines Me2P-PR-PR-PMe2, whereas the complex of the triphosphine eis -Mo (CO)4 (Ph2P-PMe-PPh2) is obtained starting with the lithiumphosphido complex cis-Mo(CO)4(Ph2PLi)2. Phenyldilithiumphosphine and the chlorophosphine complexes cis-Mo(CO)4(R2PCl)2 (R = Me, Ph) give in low yield cis-Mo(CO)4(R2P-PPh-PPh-PR2) and cis-Mo(CO)4(R2P-PPh-PR2). The mechanisms of these reactions are discussed. The {3ippjj-and { 1 H} 31 P-NMR spectra are analysed and correlated with the structures of these complexes.

	Abstract	Reaction of dicarbonyl(»y-cyclopentadienyl)(methylpropiolate)manganese(I) with various stoichiometric quantities of £er£-butyl lithium and subsequent addition of HCl or CH3OSO2F allows the isolation of vinylidene complexes of the general type CpMn(CO)2 = C = CRiR2 Ri = H, CH3; R2 = COOCH3, COf-Bu, COH(«-Bu)2). The compound with RX=H, R2 — COOCH3 adds another CpMn(CO)2 fragment, with formation of a bridged vinylidene species with a Cp2Mn2(CO)4 unit. The reaction with amide or methoxide leads to the formation of carbene complexes CpMn(CO)2 = C(Ri)CH2-COOCH3 (Rx = NH2, OCH3).
