HYDROGENOTUNGSTATO COMPLEXES WITH TIN HALOGENURES (IV): INFRARED AND MÖSSBAUER STUDIES

Polarography of Tin ( IV ) - Pyrogallol Complexes .

Biphenolate phosphine complexes of tin(IV).

The preparation and structural characterization of tin(IV) complexes supported by (2,2'-phenylphosphino)bis(4,6-di-tert-butylphenolate) ([OPO]2-) are described. The reaction of in-situ prepared Li2[OPO] with SnCl4 in THF at -35 degrees C produced [OPO]SnCl2(THF) as a THF adduct. Addition of SnCl4 to a THF solution of H2[OPO] in the presence of 2 equiv of NEt3 at room temperature led to the form...

Preparation and NMR, Mass and Mössbauer Studies of Di-and Triorganotin (IV) Derivatives of 3-(2-Furanyl)-2- Propenoic Acid

3-(2-Furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula R3SnL (R=Me, Et, n-Bu, Ph and Cy) and R2SnL2 (R=Me and n-Bu). These complexes have been characterized by elemental analyses, IR, 1H-NMR, MASS and Mössbaure spectroscopy.

Mössbauer Spectroscopic Studies of Monosubstituted Pentacyano Ferrate ( II ) Complexes ,

Mössbauer Spectra, Hexacoordinate Complexes A series of compounds Na3[Fe(CN)5RNH2] * nH 20 where R = -H, -CH3, -C2H5, n-C3H7, n-C4H9 and -CH2C6H5 and RNH2 = C5H5N have been studied by Mössbauer spectroscopy. Quadrupole splitting (A EQ) values vary in a limited range (0.68-0.80 mm/sec) indicating only small distortions in the octahedral geometry of the compounds with the substitution of various ...

synthesis and dna interaction studies of new cobalt (ii) complexes containing different dinitrogen aaromatic ligands with calf thymus dna using different spectroscopy methods

در این مطالعه بر هم کنش این چهار کمپلکس با dna تیموس گوساله توسط روش های اسپکتروفتومتری، فلوریمتری، دو رنگ نمائی دورانی، و ویسکوزیمتری بررسی شدند تا اثر استخلاف های متیل بر روی لیگاندهای فنانترولین بررسی گردد.
