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 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...
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 ...
متن کاملCrystal Structure of Nonaaquayttrium(III) Bromate at 100 K
The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...
متن کاملPREPARATION AND CRYSTAL STRUCTURE OF CaCl .[OC(NH ) ]
Calcium dichloride tetra urea was prepared by the reaction of calcium chloride with urea in aqueous solution. The crystals are monoclinic, a= 7.633, b= 12.45 1, c= 8.118 ?,? = 113.17, Z = 4, space group P 2,/a. The crystal structure was determined by single crystal X-ray methods and refined to R= 0.041. The calcium atoms are coordinated to four oxygen atoms of urea and to two chloride ions....
