Preparation and Characterization of Novel Complexes [Cr2Co(O)(C7H4O2Cl)6(Py)3] NO3 and [Fe2Mn(O)(C7H4O2C1)6 (Py)3]N03
Transition-metal carboxylate chemistry has played a key role in the conceptual development of modem inorganic chemistry. The Oxo-bridge complexes of transition metal with the general composition [M30 (O2CR)6L3]zhave been of interest for several...
Phrasal complexity in academic writing: A comparison of abstracts written by graduate students and expert writers in applied linguistics
. Biber, Gray and Poonpon (2011) have hypothesized a series of stages predicting development in writing complexity through the increased use of complex phrasal constructions. The purpose of this study is to compare abstracts by MA-level L1 Persian writers...
A 1,2-dibenzoyl-cyclopentadiene derivative as a new potential chelating agent in geological materials
In this paper, 2,3-bis(p-methoxybenzoyl)cyclopentadiene(DPMBCP) has been studied as a chelating agent and pKa value was determined by means of spectrophotometric measurement. The sigmid curve of optical density agents pH ...
The effect of phenyl substitutions on the structure and metal- ligand bond strength of copper acetylacetonate. A DFT study.
The calculated bond lengths of Cu-O and O…O are shorter in Cu(DBM)2 than the corresponding ones in Cu(AA)2 and Cu(BA)2. The Cu-O symmetric stretching frequency is higher in Cu(DBM)2 than Cu(AA)2 and Cu(BA)2. Therefore, the ...
Synthesis, characterization, and IR investigation of novel oxo-centerted, ....
Oxo-centered trinuclear carboxylates are a well-established class...
CEO Pay for Complexity and the Risk of Managerial Diversion from Multinational Diversification
The formation constants determination of α-formyl acetylacetonate complex by pH-metric titration
The copper (II) ion forms complexes with a great variety of stereochemical conformations. The stereochemistry of the copper (II) complexes appears to modulate the biological activity of the metal ion involved in many biological processes [1...
DFT calculations and NBO analysis on stability of cis and trans isomers of bis(4-amino-3-penten-2-onato)nickel(II)
The late transition metal complexes, are generally considered to be good tolerant toward polar media and thus are used as catalysts for polar monomer polymerizations [1, 2]. The aim of the present work is the modified synthesis and the improved...
Structure and vibrational assignment of cobalt(III) formylacetylacetonate
B-diketonate complexes of various metals have been used in the preparation of supported catalysts and as precursors of heterogeneous catalysts [1,2]. In this paper, the structure and vibrational spectra of cobalt(III) formylacetylacetonate, Co(FAA)3...
Translation Industry in the Light of Complexity Science: A Case of Iranian Context
In line with the fact that multidisciplinary studies as a whole have gained momentum these days, it seems that translation studies as a relatively young discipline has recently tried to embrace new findings from other ...
