Název v původním jazyce

Commensurate and incommensurate structures of the hexabromotellurate(IV) bis {dibromodiselenate(I)} ion - [(C2H5)(n)(C6H5)(4-n)P](2)[TeBr6(Se2Br2)(2)], n=0,1

Popis výsledku v původním jazyce

Structure analysis of [(C2H5)(n)(C6H5)(4-n)P](2)[TeBr6(Se2Br2)(2)] is presented for n=1 and 0 [ hereafter (I) and (II)]. Crystal (I) has been synthesized from elemental selenium, tellurium tetrabromide, ethyltriphenylphosphonium bromide and bromine. It has a standard monoclinic structure, space group P2(1)/c, and has been solved and refined to R=0.0357 for 4803 observed X-ray reflections by traditional techniques. Crystal (II), which has been prepared from elemental selenium, tellurium tetrabromide, tetraphenylphosphonium bromide and bromine, is an incommensurately one-dimensionally modulated structure with planar monoclinic superspace group. (II) has been refined to R=0.0501 for 4247 observed reflections. The modulation of the atoms that belong to theanion switches between two different basic positions, which are described by the crenel function algorithm. The modulation of the phenyl groups is much weaker and it could be refined within the rigid-body approximation. The TeBr6 octahed
