Crystal Structure and Magnetic Properties of the Novel Hollandite Ba1.3Co1.3Ti6.7O16
Single crystals of the new barium hollandite Ba1.3Co1.3Ti6.7O16 were obtained from a BaCl2 flux (I2/m, Z = 1, a = 9.9470(4), b = 2.9714(2), c = 10.2260(5) Å, β = 90.906(2)◦). In the crystal structure piles of Ba atoms are situated within a framework of edgeand vertex-sharing octahedra (Co,Ti)O6. The composition was deduced from microprobe analyses, structure refinements and charge balance argum...
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....
متن کاملNi2As2O7 pyrochlore nanomaterial: Solid state synthesis, crystal structure determination, crystal phase growth study and physical properties
Nanostructured Ni2As2O7 semiconductor samples were synthesized by a solid state method among As2O3 and Ni(NO3)2.6H2O raw materials at 650 °C (S1) and 750 °C (S2) as reaction temperatures. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and F...
