Computing stoichiometric molecular composition from crystal structures
Crystallographic investigations deliver high-accuracy information about positions of atoms in crystal unit cells. For chemists, however, the structure of a molecule is most often of interest. The structure must thus be reconstructed from crystallographic files using symmetry information and chemical properties of atoms. Most existing algorithms faithfully reconstruct separate molecules but not ...
متن کاملCRYSTAL STRUCTURE OF SODIUM-POTASSIUM .ANTIMONIDE (NaiKSb)
X-ray analysis of Na2KSb a photoemissive material discovered by Sommer has led to the determination of its crystal structure. The unit cell is described by the space group Fm3m-01l5 with four antimony atoms at (0,0,0; O,t,!; t,O,t; t,t,O) + 0,0,0; four potassium atoms at ( ) + t,t,! and eight sodium atoms at ( ) + t,t,t and t,t,t. The crystal structure of Na2KSb has a great resemblance to that ...

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 اولDensity Functional Studies on Crystal Structure and electronic properties of Potassium Alanate as a candidate for Hydrogen storage
Potassium Alanate is one of the goal candidates for hydrogen storage during past decades. In this report, initially the Density Functional Theory was applied to simulate the electronic and structural characteristic of the experimentally known KAlH4 complex hydride. The relaxation of unit cell parameters and atomic positions was performed until the total residual force reduced less than 0.001ev ...
متن کاملSYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]
The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
