The str.ctur. of （E）-N-[（E）-3-[（lr.2r.-2-（3,4-dibr.mo-phenyl）-l-flur.-cyclopr.pyl]- allylidene]-2-0-tolyl-acetamide （C21HIsONFBr., Mr.= 479.18） has been deter.ined by X-r.y single- cr.stal diffr.ction and theor.tical calculations to establish the configur.tion, ster.ochemistr. and a stable confor.ation of the molecule. The compound cr.stallizes in the monoclinic space gr.up P21/c, a = 28.3452（10）, b = 4.9311（10）, c = 14.257（2） A, fl = 102.7654（10）, V = 1943.5（5） A3 and Z = 4.

Str.ctur.l and electr.n char.e density studies of a nonlinear. optical compound 4,4 di-methyl amino cyano biphenyl

引用

Chinese Physics B 2014年第1期23卷 312-317页

作者： Naima Boubegr., Abdelkader.Chouaih, Mokhtar.a Dr.ssi and fodil Hamzaoui achouaih@*** []Labor.toir. de Technologie et Pr.pr.ts du Solide (LTPS) Universit Abdelhamid Ibn Badis de Mostaganem 27000 Mostaganem Algeria

The 4,4 dimethyl amino cyano biphenyl cr.stal (DMACB) is char.cter.zed by its nonlinear.activity. The intr. molecular.char.e tr.nsfer.of this molecule r.sults mainly fr.m the electr.nic tr.nsmission of the electr.-acceptor.(cyano) and electr.-donor.(di-methyl-amino) gr.ups. An accur.te electr.n density distr.bution ar.und the molecule has been calculated based on a high-r.solution X-r.y diffr.ction study. The data wer. collected at 123 K using gr.phite-monochr.mated Mo K α r.diation to sin(β)/λ = 1.24 Å−1. The integr.ted intensities of 13796 r.flections wer. measur.d and r.duced to 6501 independent r.flections with I ≥ 3σ(I). The cr.stal str.ctur. was r.fined using the exper.mental model of Hansen and Coppens (1978). The cr.stal str.ctur. has been validated and deposited at the Cambr.dge Cr.stallogr.phic Data Centr. with the deposition number.CCDC 876507. In this ar.icle, we pr.sent the ther.al motion and the str.ctur.l analysis obtained fr.m the least-squar. r.finement based on F2 and the electr.n density distr.bution obtained fr.m the multipolar.model.

Deter.ination of electr.static par.meter. of a coumar.n der.vative compound C_(17)H_(13)NO_3 by x-r.y and density functional theor.

This wor. is devoted to the exper.mental deter.ination of the electr.static pr.per.ies of the molecular.4-methyl-7-（salicylidene amino） coumar.n（C17H13NC3） using high r.solution x-r.y diffr.ction data. The exper.mental r.sults ar. compar.d with those obtained theor.tically fr.m calculation type ab initio. The exper.mental investigation is car.ied out using the molecular.electr.n char.e density distr.bution based on the multipolar.model of Hansen and Coppens. However.the theor.tical calculations ar. conducted by using the molecular.or.ital B3 LYP method and the Har.r.e-Fock（HF） appr.ximation with the basis set 6-31G（d,p） implemented in the Gaussian pr.gr.m. In addition to the str.ctur.l analysis,the ther.al agitation is also analyzed in ter.s of r.gid blocks to ensur. a better.pr.cision of the r.sults. Subsequently, the electr.static atomic and molecular.pr.per.ies such as the net char.es, the molecular.dipolar.moment to highlight the natur. of char.e tr.nsfer.existing within the molecule studied ar. der.ved. Mor.over. the obtained electr.static potential enables the localization of the electr.positive and the electr.negative par.s of the investigated molecule. The pr.sent wor. r.por.s in detail the obtained electr.static pr.per.ies of this biologically impor.ant molecule.

The pr.sent wor. per.or.s self-consistent ab initio full-potential linear.muffin-tin or.ital (FP-LMTO) method to study the str.ctur.l and electr.nic pr.per.ies of the ter.ar. ZnxCd1-xSe alloy, based on density functional theor. (DFT). In this appr.ach, both the local density appr.ximation (LDA) and the gener.lized gr.dient appr.ximation (GGA) wer. used for.the exchange-cor.elation potential calculation. The gr.und-state pr.per.ies ar. deter.ined for.the bulk mater.als CdSe, ZnSe and their.alloy in cubic phase. In par.icular. the lattice constant, bulk modulus, electr.nic band str.ctur.s and effective mass. We mainly showed deviation of the lattice par.meter.and bulk modulus fr.m Vegar.’s law of our.alloys. We also pr.sented the micr.scopic or.gins of the gap bowing using the appr.ach of Zunger.et al. The r.sults ar. compar.d with other.theor.tical calculations and exper.mental data and ar. in r.asonable agr.ement.
