this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
the effect of alkyl substituents on the c-phenyl and/or the n-phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. the predominant configuration in chcl3 is determined by steric and electronic effects. substituents on the c-phenyl ring favor the cis configuration, while substituents in the n-phenyl ring favor a trans configuration. t...

In this study the interaction of cis-PtCl2(NH3)2 complex and graphene were investigated with MPW1PW91method in gas and solvent phases. The solvent effect was examined by the self-consistent reaction fieldtheory (SCRF) based on Polarizable Continuum Model (PCM). The selected solvents were chloroform,chlorobenzene, bromoethane, dimethyldisulfide, and dichloroethane. The solvent ...
کمپلکس cis-[ptcl2(dppb)] از واکنش کمپلکس cis, trans-[ptcl2(sme2)2] و لیگاند dppb و کمپلکس cis-[ptcl2(dpppe)] از واکنش dpppe و k2ptcl4 با راندمان بالا به دست آمد. کمپلکسهایcis-[ptbr2(p2)] (p2 = dppa, dppb, dpppe) نیز از واکنش k2ptbr4و لیگاندهای فوق تشکیل شدند. همچنین کمپلکس های cis-[ptx2(p2)] (p2 = dppf, dppm, dppe, dppp, dppb, dpppe ; x = br, i) از واکنش کمپلکس هایcis-[ptcl2(p2)] و kx (x...
In [his research endo-3-diphenylphosphino -(IR)(+) camphor as a ligand was synthesised. 1.3 mmol of IrC12(NCPh)2 was added to the solution of 2.7 mmolligand in 15 ml dicloromethane, and after one hour it was evaporated at reduced pressure. By addition of methanol microcrystals of yellow complex of lridium(I) with 78% yield was obtained. Crystal structure of the above complex are orthorho...
در این تحقیق، از روش آسان و موثر رفلاکس جهت سنتز نانوذرات مس ایندیوم سولفید استفاده شد و نانو ساختار های متنوع روی اکسید با بکارگیری روش هیدروترمال سنتز شدند. سپس با کمک یک فرایند حرارتی نانوکامپوزیت zno/cis تهیه شد. محصولات به وسیله روش های پراش اشعه ایکس (xrd)، طیف سنجی زیر قرمز (ft-ir)، میکروسکوپ الکترونی روبشی (sem) و طیف سنجی uv- visمورد شناسایی قرار گرفتند. تصاویر sem، مورفولوژی نانوذره ب...
This paper analyzes the complex characteristic of enterprise competitive intelligence system (CIS). Establishment of CIS of enterprise is an important approach to promote the research leve1 of enterprise CIS. All methods and techniques can be integrated from other science fields into CIS research through CIS. The author put up with the architecture of CIS, which includes fundamental architectur...
