Ab-initio Molecular Dynamics Study on Crystal Structure of Beta-dicalcium Silicate
The crystal structures and hydraulic activities of β and γform dicalcium silicates (β-C2S, γ-C2S) were analyzed by ab-initio calculation based on quantum mechanics. The mean distances less than 4 Å to the neighboring Ca atoms for all of independent Ca atoms were calculated within unit cell. Ca-Ca mean distances are 3.56 Å in β-C2S and 3.75 Å in γ-C2S. The shortening of Ca-Ca distance causes ins...
متن کاملCrystal structure of a mixed solvated form of amoxapine acetate
The mixed solvated salt 4-(2-chloro-dibenzo[b,f][1,4]oxazepin-11-yl)piperazin-1-ium acetate-acetic acid-cyclo-hexane (2/2/1), C17H17ClN3O(+)·C2H3O2 (-)·C2H4O2·0.5C6H12, crystallizes with one mol-ecule of protonated amoxapine (AXPN), an acetate anion and a mol-ecule of acetic acid together with half a mol-ecule of cyclo-hexane. In the centrosymmetric crystal, both enanti-omers of the protonated ...

The mixed-valence μ-oxide Sn12 cluster, deca-carbonyl-tetra-μ4-oxido-hexa-μ3-oxido-tetra-kis-[μ-2,2'-(pyridine-2,6-di-yl)bis(1,1-di-phenyl-ethano-lato)]deca-tin(II)ditin(IV)dimolyb-denum(O)(2 Mo-Sn) toluene hepta-solvate, [Mo2Sn12(C33H27NO2)4O10(CO)10]·7C7H8, has a crystallographically imposed inversion centre. The asymmetric unit also contains three and a half toluene solvent mol-ecules, one o...
متن کاملSYNTHESIS 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 کاملCrystal structure of a heterometallic coordination polymer: poly[diaquabis(μ7-benzene-1,3,5-tricarboxylato)dicalcium(II)copper(II)]
In the title complex, [Ca2Cu(C9H3O6)2(H2O)2] n , the CaII and CuII cations are bridged by the benzene-1,3,5-tri-carboxyl-ate anions (BTC3-) to form the coordination polymer, in which each BTC3- anion bridges two CuII and five CaII cations with a μ7 coordination mode. The CuII cation, located at an inversion centre, is in a nearly square-planar geometry defined by four O atoms from four bridging...
