Copper(I) complexes of a new participative triphosphane ligand (2H) have been prepared and structurally characterized: in particular, [Cu(2H)I] [Cu(2)]2. Hydrogenation the latter species afforded trimetallic hydride [Cu3(2)2(μ-H)] or, presence BEt3, [Cu(2H)(HBEt3)]. Their formation evidences transient [Cu(2H)H] formed by hydrogenolysis Cu–N bond [Cu(2H)(HBEt3)] behaves like complex inserts CO2 ...

The title compound, [Zn(C(10)H(11)N(4)O(2))(2)]·2H(2)O, was prepared by the reaction between Zn(CH(3)COO)(2)·2H(2)O and 2-hydroxy-imino-N'-[1-(2-pyrid-yl)ethyl-idene]propano-hydrazide (Hpop). The central Zn(II) atom has a distorted tetra-gonal-bipyramidal coordination geometry formed by two amide O atoms and four N atoms of two azomethine and two pyridine groups. In the crystal, complex mol-ecu...

SAPO-11 is synthesized from silicoaluminophosphate in the presence of di-n-propylamine as a template. The results show that sample obtained has good crystallinity, 396m2/g BET surface area, and 0.35 cm3/g pore volume. hydroisomerization activity (0.25)Pt (1)Zr (0.5)W/SAPO-11 catalyst was determined using n-decane base oil. All experiments were achieved at fixed bed plug flow reactor temperature...

A class of indecomposable representations of Uq(s`n) is considered for q an even root of unity (qh = −1 ) exhibiting a similar structure as (height h ) indecomposable lowest weight Kac-Moody modules associated with a chiral conformal field theory. In particular, Uq(s`n) counterparts of the Bernard-Felder BRS operators are constructed for n = 2, 3 . For n = 2 a pair of dual d2(h) = h dimensional...

A series of pentacyanoferrate complexes, N a3[F e (C N )5L ] /jH20 , where L = (C H 3) 2N H , (C 2H 5) 2N H , (C 2H 5)3N , (C 3H 7)2N H , (C 4H 9)2N H , (C 4H 9)3N and (C 6H 5)2N H were studied by Mössbauer and infrared spectroscopy. A ll the complexes exhibited two line spectra with A E Q = 0.73—1.92 mms“1 and <5 = —0.04—0.49 m m s '1 (w.r.t. SNP) and can be divided into two groups with well d...

Discrete fractional Gaussian noise (dFGN) has been proposed as a model for interpreting a wide variety of physiological data. The form of actual spectra of dFGN for frequencies near zero varies as f(1-2H), where 0 < H < 1 is the Hurst coefficient; however, this form for the spectra need not be a good approximation at other frequencies. When H approaches zero, dFGN spectra exhibit the 1 - 2H pow...

(7-Hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid methyl ester(1) upon reaction with ethyl bromoacetate furnishes (7-ethoxycarbonylmethoxy-2-oxo-2H-chromen-4-yl)-acetic acid methylester (2), which on treatment with 100% hydrazine hydrate yields (7-hydrazinocarbonylmethoxy-2-oxo-2H-chromen-4-yl)-acetic acid hydrazide (3). The condensation of compound 3 with different aromatic aldehydes afforded a se...
