 Title    XPS Spectra of Copper and Nickel Biuret Complexes — Observations of Intense Satellite Structure in the 2P Spectrum of a Copper(III) System  
 Abstract    A series of copper and nickel biuret complexes has been studied by X-ray photoelectron spectroscopy (XPS). The results include one of the first reports of the XPS spectrum of a copper(III) complex. Significantly, this diamagnetic complex exhibits intense satellite structure in both the Cu 2P3/2 and Cu 2Pi/2 regions. The isoelectronic nickel(II) complex shows no comparable satellite structure.

 Title    Oxidative Addition of Pseudohalogen to [P(OPh)3]4Ni  
 Abstract    The title compound reacts with cyanogen halides, XCN (X = Br or I) to give the com-plexes L2(X)(CN)Ni (L = P(OPh)3, X = Br or I). The oxidative addition of (SCN)2 and (SeCN)2 to the same compound results in the formation of L2Ni(XCN)2 (X = S or Se). All the complexes have been characterized by elemental analysis, and IR, iH NMR and electronic spectra.

 Title    Uniform Sidearm Derivatisations in a Tetrapodal Pentaamine: Ligands with NN4 O4 Donor Sets, and a Bis(Ferrocenecarbaldehyde Aminal)  
 Abstract    The tetrapodal pentaamine 2,6-C5H3N[CMe(CH2NH2)2l2 (pyN_u 1) readily reacts with four equivalents of 2-hydroxyphenyl-substituted carbonyl compounds, such as (i) 2-hydroxybenz-aldehyde, (ii) 2,4-dihydroxybenzaldehyde, (iii) 3,5-di-rm-butyl-2-hydroxybenzaldehyde, and (iv) 2-hydroxyacetophenone, to give the corresponding Schiff base derivatives with N N 4O .1 donor sets (i: 2; ii: 3, iii: 4; iv: 5). With ligand 5, two transition metal complexes (M = Ni1 (6), Cu1 1 (7)) have been isolated, which are dinuclear and contain square-planar M(N202) units, linked by a pyridine-derived spacer whose nitrogen atom is uncoordinated. The reaction of 1 with ferrocenecarbaldehyde affords, under neutral conditions and irrespective of an excess of the aldehyde present, the bis(aminal) 8 as the major product, in which the two 1,3-propylenediamine subunits of 1 have condensed with two carbaldehyde moieties to give two 1,3-diazacyclohexane rings. All compounds have been characterised by IR spectroscopy and elemental analysis, as well as 'H and l3C NMR spectroscopy (except paramagnetic 7). The crystal structures of compounds 2, 6, 7, and 8 have been determined.

 Title    The Ni(0)—C0 2 System: Structure and Reactions of [Ni(PCy 3 ) 2 (i/ 2 -C0 2 )]  
 Abstract    The reactions of a variety of bis(tricyclohexylphosphine)nickel species with C0 2 have been studied. The product of the reaction is solvent dependent: in toluene the known complex [NiL 2 (/7 : -C0 2)]-toluene (L = PCy 3) is formed while in ether or pentane a binuclear complex [(NiL 2) 2 (?;-C0 2)] results through the intermediacy of the solvent free species [NiL 2 (// 2 -C0 2)] the structure of which has been determined by X-ray crystallography.

 Abstract    Single crystals of the new compound C aN i(V 0)(P 04)2 have been prepared by solid state reactions below the melting point of the oxide mixture in evacuated quartz tubes. X-ray inve­ stigations ledoto orthorhom bic symmetry, space group D2£-Pnma, a -14.113(1), b -6.408(1), c = 7.364(1) A, Z = 4. The crystal structure shows J. [N i0 4] and J. [V 0 6P20 3] polyhedra chains closely related to analogous chains in the isotypic compound CdV20 (P 0 4)2. The short V -0 distance of 1.66 A indicates a vanadyl group as the main difference to CdV20 (P 0 4)2. The short 0 -0 distance of 2,395 A of the edge-sharing P 0 4 tetrahedra and V 0 6 octahedra is discussed.

 Title    Formation of r71-P-(2-Phosphinophenol)Ni(0)(PMe3)3 and Oxidation to cjs/fraws-Bis(2-phosphinophenolato)nickel(II) Complexes  
 Abstract    o-Phosphinophenols 1 (P ^ O H) react with equimolar amounts of Ni(PMe3)4 at low tempera­ tures to give yellow Ni(0) complexes such as [(HO~P)Ni(PMe3)3] 2a with only P coordination of the P ^ O H ligand. Oxidation of solutions of 1 and Ni(PMe3)4 by dioxygen leads to brown bis(o-phosphinophenolato-P^O)nickel chelate complexes 3a-d. Structure elucidation by NM R is consistent with a m-square planar geometry for 3a-c and a rrans-square planar solution struc­ ture of the terr-butylphenylphosphino derivative 3d. The geometric isomers were distinguished by different ranges of phosphorus coordination shifts and 3lP-l3C-2 and 3IP-13C-1 coupling

 Title    Zur Frage biogener Anreicherungen von Vanadium und Nickel in Pflanzen des Karbonzeitalters The Question of Biogenous Enrichments of Vanadium and Nickel in Plants of the Carbon Age  
 Abstract    O riginal carbonaceous m aterial of fossile carbon plants from the divisions of the Equisetophyta (Calam ariaceae), Lycophyta (Lepidodendraceae, S igillariacea e), Filicophyta (F ilicatae), and Sper-matophyta (Pteridospermatae, Cordaitidae) was analyzed by atomic absorption spectroscopy on its content of the trace metals vanadium and nickel. The average V-content was found to be 1 0 to 100 fold higher than that of the neighbouring coal beds or that of the embedding materials, while the Ni-concentrations were found to be almost in the same range. The highest contents of V and N i were found in the Calamariaceae and in the Pteridospermatae. The V-and Ni-contents of the fossile carbon plants are compared to those of related recent plant genera (clubmosses, horse­ tails, fern s), which were analyzed by 46 representative samples. A possible biogenous enrichment of V and N i in plants of the carbon age is discussed.

 Title    Novel Dinucleating Ligand Systems Containing Two Adjacent Coordination Compartments of the Potential Triamidoamine-Type -Nickel(II) and Cobalt(II) Coordination Chemistry  
 Abstract    The preparation of novel dinucleating pyrazolate ligands H5L3 -H5L8 carrying chelating side arms with appending secondary amine functions is reported. Following different synthetic routes, either CH2CF3, C6H2F3 , or CftF? moieties can be introduced as substituents at the termi­ nal nitrogen atoms. These systems are reminiscent of two coupled coordination compartments of the potential triamidoamine-type. Crystallographic analyses of a series of bimetallic complexes of the CH2CF3-substituted ligand H5L4 with NiCh and C0 CI2 reveal manifold coordination modes in the solid state, resulting from the facile detachment of a single or several N-donor sites from the metal centers. Coordination number sets {4/6} (in H5L4Co2CU) and {5/6} (in H4L4Ni2Cl3, H4L4Co2Cl3 and H5L4Ni2CL) are thus observed. In the non-deprotonated HsL-type systems the remaining protons are found to be scavenged by a pyrazolate-N (in H5L4Ni2CU) or an amine function of a ligand side arm (in H ^ C o iC U).

 Title    Nickel Complexes of N-Alkylated Derivatives of 2,6-Bis(aminomethyl)- 4-te/t-butyl-thiophenol  
 Abstract    The syntheses of N-alkylated derivatives of the arenethiol 4-terf-butyl-2,6-(diaminomethyl)-thiophenol and their coordination properties are reported. Compounds 4-terf-butyl-2,6-di(/V-iso-propyl-aminomethyl)thiophenol (3) and 4-terf-butyl-2-(AMsopropyl-aminomethyl)-6-hydroxy-methylthiophenol (6) react with Ni(II) salts to give compounds of composition [Ni(3)2]-2HC1 (7) and [Ni(6)2] (8). The solid-and solution-state structures of both complexes consist of mononuclear complexes with four-coordinate nickel(II) ions in approximately planar trans-N2S2 coordination environments. In contrast to the parent arenethiol 4a, the sterically more encumbered ligands do not form dinuclear complexes.
