Platinum(IV) complexes with general formulas [Pt(L1-2)(2)Cl-4]. where L1-2 are 3-acetylpyridine (1) and 4-acetylpyridine (2) respectively, and [Pt(HL3-5)(2)Cl-2], where H2L3-5 are 2,3-pyridinedicarboxylic acid (3), ...
Structural, biological and in-silico study of quinoline-based chalcogensemicarbazones
(Elsevier, 2020)
In this work pharmaceutical application of focused library of six quinoline-based chalcogensemicarbazones (QBCs) was tested through determination of their antimicrobial activity against twenty-eight Gram-negative and ...
Novel trans-dichloridoplatinum(II) complexes with 3-and 4-acetylpyridine: Synthesis, characterization, DFT calculations and cytotoxicity
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2009)
Novel complexes of platinum(II) with 3- (1) or 4-acetylpyridine (2) have been synthesized and characterized by elemental analyses, IR, H-1 and C-13 NMR spectroscopy. Single crystal X-ray diffraction revealed the trans ...
Nucleus-independent chemical shift profiles along the intrinsic distortion path for Jahn-Teller active molecules. Study on the cyclopentadienyl radical and cobaltocene
(Serbian Chemical Soc, Belgrade, 2015)
The aromatic/anti-aromatic behavior of the cyclopentadienyl anion (Cp-), bis(eta(5)-cyclopentadienypiron(II) (Fe(Cp)(2)), as well as of the Jahn-Teller (JT) active cyclopentadienyl radical (Cp-center dot) and bis(eta(5)- ...
Magnetic criteria of aromaticity in a benzene cation and anion: how does the Jahn-Teller effect influence the aromaticity?
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The aromatic/antiaromatic behavior of the Jahn-Teller UT) active benzene cation and anion has been investigated using Density Functional Theory (DFT) calculations of Nuclear Independent Chemical Shifts (NICS) and magnetic ...
DFT investigation of the influence of Jahn-Teller distortion on the aromaticity in square-planar arsenic and antimony clusters
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Density functional theory (DFT) calculations were performed to investigate aromaticity of tetra atomic metalloid clusters, As-4(2-) and Sb-4(2-). The careful analysis of nuclear independent chemical shifts (NICS) revealed ...
Carbon-hydrogen bond activation by a titanium neopentylidene complex
(Taylor & Francis Ltd, Abingdon, 2016)
The titanium neopentylidene complex (PNP)Ti=(CHBu)-Bu-t((CH2Bu)-Bu-t), PNP=N[2-(PPr2)-Pr-i-4-methylphenyl](2)(-), can activate both sp(2) and sp(3) C-H bonds under mild conditions. In this work, we studied the reaction ...
Strong Stacking Between Organic and Organometallic Molecules as the Key for Material Design
(Wiley-Blackwell, Malden, 2015)
Very attractive properties of organic-inorganic materials consisting of planar molecules, namely magnetism, conductivity. non-linear optics and catalysis. are highly dependent on the stacking interactions. Metal-chelate ...
