A spectrophotometric study of osmium (VIII) complex of 1-hydroxy 2- pyridine thione (HPT) is presented. A red-violet complex, 0 s (HPT) is formed in a highly acidic solution, and shows maximum absorbance at 500 nm with molar absorptivity of 5.12 x 101. mol . cm . Beer's law is obeyed in the range of 3-60 ppm. Sandel's sensitivity of the method is 0.37 ?g.cm per0.001 ab sorbance unit. V (V)...

The title compound, [Sn(4)(C(8)H(17))(8)O(2)(C(6)H(5)N(2)O(2))(4)], is a tetra-nuclear Sn(IV) complex, built up by inversion symmetry around the central Sn(2)O(2) ring. The Sn(IV) coordination geometries are distorted SnO(3)C(2) trigonal-bipyramidal and distorted SnO(4)C(2) octa-hedral. The three-coordinate μ(3)-oxido bridging O atom in the Sn(2)O(2) ring is attached to three Sn atoms. All non-...

The title complex, [Sn(IV)(C(44)H(28)N(4))(CNO)(OH)], exhibits substitutional disorder of the OH(-) and OCN(-) axial ligands. Thus, the cyanato-O ligand and the hydroxyl group bonded to the central Sn(IV) atom share statistically the axial position. The Sn(IV) ion is hexa-coordinated by the four N atoms of the pyrrole rings of the tetra-phenyl-porphyrin (TPP) and the O atoms of the two disorder...

Silver (SN) nanoparticles were re‐dispersed in aqueous solution of Pluronic F127 and complexed with the antioxidant, alpha‐ Lipoic acid (LA). The nanoparticle ‐ LA complex (SN‐LA) was characterized using SEM. SN‐ LA exhibited DPPH radical scavenging activity in vitro and anti‐ inflammatory activity against acute and chronic paw models of edema in mice. SN‐LA protected ...

The spaces H(M, L ) of holomorphic sections of the powers of an ample line bundle L over a compact Kähler manifold (M, ω) have been generalized by Boutet de Monvel and Guillemin to spaces H J (M, L ) of ‘almost holomorphic sections’ of ample line bundles over an almost complex symplectic manifold (M, J, ω). We consider the unit spheres SH J(M, L N ) in the spaces H J(M, L N ), which we equip wi...

where l > 0 and {dk0, dk1} is a so-called symmetrically coherent pair, with dk0 or dk1 the classical Gegenbauer measure (x−1) dx, a > −1. If dk1 is the Gegenbauer measure, then Sn has n different, real zeros. If dk0 is the Gegenbauer measure, then Sn has at least n−2 different, real zeros. Under certain conditions Sn has complex zeros. Also the location of the zeros of Sn with respect to Gegenb...

The title complex, [Sn(CH(3))(2)(C(8)H(10)O(4))](n), was synthesized from cis-cyclo-hexane-1,2-dicarboxylic acid and dimethyl-tin dichloride. The complex has a bridging bis-bidentate carboxyl-ate group resulting in a zig-zag chain structure parallel to [001]. The Sn atom is six-coordinated and displays a distorted octa-hedral geometry.

The dinuclear title complex, [Sn(2)(C(7)H(6)Cl)(4)(C(9)H(16)NO(2)S(2))(4)], lies on a center of inversion. The Sn(IV) atoms are chelated by one of the two carboxyl-ate ions; the other carboxyl-ate ion bridges two metal atoms. The geometry of the six-coordinate Sn(IV) atom is a distorted trans-C(2)SnO(4) octa-hedron [C-Sn-C = 155.32 (8)°].

Two molar amounts of arynes were found to insert into a Sn-Sn bond of a distannane in the presence of a sub-stoichiometric amount of a palladium-phosphite complex, affording straightforwardly 2,2'-distannylbiaryls.
