PREPARATION AND CHARACTERIZATION OF Mn (III) COMPLEXES
We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported. On the basis of solution spectra, some of these complexes seem to be typically distorted

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولSilver Tetrafluoroborate Complex of a Lower Rim Phosphorylated Calix[4]arene; Preparation and CHaracterization
Siilver tetrafluoroborate complex of 5.11.17.23-tetra-tert-butyl-25-26,27,28-tetrakis (diphenylphosphinoylmethoxy)calyx[4]arene (L) has been synthesized by reaction of silver tetrafluoroborate and L in dichloromethane at room temperature. The complex formed has a 1:1 metall/ligand ratio. 1H and 31P NMR data support an encapsulated structure of the complex in which silv...
متن کاملStructure and photoluminescence of silver(i) trinuclear halopyrazolato complexes.
Five halogen substituted pyrazolates, 4-chloro-3,5-diisopropylpyrazole (4-Cl-3,5-iPr2pzH), 4-bromo-3,5-diisopropylpyrazole (4-Br-3,5-iPr2pzH), 4-iodo-3,5-diisopropylpyrazole (4-I-3,5-iPr2pzH), 4-chloro-3,5-diphenylpyrazole (4-Cl-3,5-Ph2pzH), and 4-bromo-3,5-diphenylpyrazole (4-Br-3,5-Ph2pzH), were conveniently prepared by halogenation of the appropriate pyrazoles with N-halosuccinimides (NXS) (...
متن کاملCrystal and Molecular Structure of Novel Silver-Diphosphine Complexes
It has been shown that the bis-chelated complex Au(dppe)2CI, dppe diphenylphosphinoethane and derivatives are active against a series of tumor cell lines [1]. Later, closely related silver diphosphine complexes were shown to be cytotoxic against B melanoma cells in vitro and P 388 leukemia in mice [2]. Furthermore, Cu-diphosphine complexes are also biologically active [3]. The diphosphine ligan...
