Synthesis and Crystal Structure of a Novel Six-Coordinate Gallium (III) Complex
The reaction of gallium (III) nitrate octahydrate with the proton transfer compound (pydaH2)2+ (pydc)2– ( where pyda is 2,6-pyridinediamine and pydcH2 is 2,6-pyridinedicarboxylic acid) leads to the formation of (C5H8N3) [Ga(C7H3NO4)2] · 4H2O · CH3OH. The crystal system of the anionic complex is triclinic with space group Pī and two molecules per unit cell. The unit cell parameters are a=10.23...

جنبه های گوناگونی از زندگی در ایران را از جمله سبک زندگی، علم و امکانات فنی و تکنولوژیکی می توان کم یا بیش وارداتی در نظر گرفت. زبان انگلیسی و روش تدریس آن نیز از این قاعده مثتسنی نیست. با این حال گاهی سوال پیش می آید که آیا یک روش خاص با زیر ساخت های نظری، فرهنگی اجتماعی و آموزشی جامعه ایرانی سازگاری دارد یا خیر. این تحقیق بر اساس روش های ترکیبی انجام شده است.پرسش نامه ای نیز برای زبان آموزان ...
SYNTHESIS AND CRYSTAL STRUCTURE OF [Pph ] [WS (CUNCS) ] A. Taeb A. Beheshti and N.K. Javadi SYNTHESIS AND CRYSTAL STRUCTURE OF [Pph ] [WS (CUNCS) ]
The crystals of [WS (CuNCS) ] anion have been isolated from CH ,CI solution and examined by X-ray structural analysis as well as by IR spectroscopy. The unit cell is monoclinic with a= 14.3796(13), b= 18.039(1 I), c= 22.5956(23)& P= 96.053(8)', space group P2,/n (14), Z= 4. The crystal structure was refined by the least-squares calculations to a final R-value of 0.0398(Rw= 0.0443) for 2777 u...
متن کاملSynthesis, Characterization, and Crystal Structure Determination of a New Copper(II) Complex: [H2en][Cu(pydc)2].2H2O
The new complex of [H2en][Cu(pydc)2].2H2O (1) (where H2en and pydc are ethylenediammonium and 2,6-pyridinedicarboxylate, respectively) was synthesized by the reaction of a mixture of ethylenediamine (en) and 2,6-pyridinedicarboxylic acid (H2pydc) in a mixture of CH3OH/H2O as solvent. This complex was fully characterized by elemental analysis, IR, UV–Vis spectroscopy as well as single-crystal X-...
متن کاملX-Ray, Crystal Structure and Solution Phase Studies of a Polymeric SrII Compound
In the crystal structure of the title polymeric compound, [C42H38N6O33Sr5.2(H2O)]n, five independent metal atoms (Sr1-Sr5) have different coordination environments. The Sr1 and Sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively....
