The first X-ray structure of an isatin (2,3-indolinedione, isaH) metal complex, bis(isatinato)memury(II) (C16H8N2O4Hg) (1), was determined. (1) was obtained from the reaction of isaH with mercury(II) acetate in methanol. Analogously, treatment of sodium saccharinate and mercury(II) acetate in methanol yielded Hg(saccharinato)2•0.5CH3OH (3). (1) crystallizes in the monoclinic system, space group P21/a with a = 7.299(1) Å, b = 8.192(1) Å, c = 11.601(1) Å , β = 105.82(1)°, V = 667.4 Å3, Z = 2, Dcalc = 2.452 g cm−3, MoKα radiation(λ = 0.71073 Å), μ = 115.5 cm-1, F(000) = 460, 21(1) °C. The structure was refined on the basis of 2023 observed reflections to R= 0.044. The two deprotonated, non coplanar isa ligands are trans to each other in a head to tail orientation and bound to the Hg through the nitrogen in a linear N-Hg-N arrangement. The Hg atom is at the center of symmetry of the complex and displaced by 0.62 Å from the two planes of the isa ligands (τ Hg-N1-C2-O2= -16°). The Hg-N bond length is 2.015 Å. Noπ-aryl-memury(ll)-π-aryl stacking interaction was observed either in the solid state or in the solution state. The IR, electronic, and H1 and C13NMR spectral data of (1) and (3) suggest binding of the memury to the heterocyclic nitrogen, in agreement with the crystal structure determination of (1).

AbstractThe synthesis and crystal structure determination of d,l-Co(en)3.Ga3P4O16, xH2O (Pnna, a = 8.6502(9), b = 21.528(3), c = 13.717(2) Å) is described. This novel layered material contains Ga3P4O163- macroanions. The preparation and preliminary catalytic testing of a vanadium doped aluminophosphate that is isostructural with the gallophosphate is also discussed.

Electroactive Species

An analytical application of chronoamperometry for determination of electroactive species not requiring standardization is described in this paper. It is based upon the separation of current component limited by linear diffusion from that limited by cylindrical contribution to the total flux of determined substance to the cylindrical (wire) Pt-semimicroelectrode (radius 0.02 mm and length 15 mm). The absolute method of determination was verified with o-dianizidine, ferrocyanide, ascorbic acid and dopamine. The optimalization of radius of the cylindrical electrode to minimize the determination error is also presented.
