Variable character of O O O and M O O bonding in side - on ( 2 ) 1 : 1 metal complexes of O 2
The structures and the OOO and MOO bonding characters of a series of reported side-on ( 2) 1:1 metal complexes of O2 are analyzed by using density functional theory calculations. Comparison of the calculated and experimental systems with respect to OOO bond distance, OOO stretching frequency, and OOO and MOO bond orders provides new insights into subtle influences relevant to O2 activation proc...
متن کاملSynthesis, Spectral Characterization, and Antibacterial Activity of Some New Azomethine-Metal Complexes Derived from Vanillin
Synthesis and characterization of Schiff base with solid metal complexes derived from Vanillin and 2-amino-2ethyl-1, 3-propanediol (VAEPD) has been carried out. Structural elucidation of the Schiff base and its metal complexes [Cu(II) and Co(II)] were analyzed on the basis of various spectra like IR, electronic absorption spectra, NMR, ESR, TG-DTA and magnetic moments. From the spectral study, ...

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.
2-Hydroxy-3-methoxybenzaldehyde (o-vanillin) revisited
The structure of ortho-vanillin, C(8)H(8)O(3), has been revisited with modern methods and at low temperature (100 K). The previous structure [Iwasaki et al. (1976 ▶). Acta Cryst. B32, 1264-1266] is confirmed, but geometric precision is improved by an order of magnitude. The C atom of the meth-oxy group lies close to the benzene ring plane, which is the most common geometry for -OMe groups lying...
متن کاملSynthesis, Spectral Characterization, and Biological Evaluation of Transition Metal Complexes of Bidentate N, O Donor Schiff Bases
New series of three bidentate N, O donor type Schiff bases (L (1) )-(L (3) ) were prepared by using ethylene-1,2-diamine with 5-methyl furfural, 2-anisaldehyde, and 2-hydroxybenzaldehyde in an equimolar ratio. These ligands were further complexed with Co(II), Cu(II), Ni(II), and Zn(II) metals to produce their new metal complexes having an octahedral geometry. These compounds were characterized ...
