The crystal structure of CuSb2O3Br : Slabs from cubic Sb2O3 interspersed between puckered hexagonal CuBr-type layers

Mayerová, Zuzana ; Johnsson, Mats LU and Lidin, Sven LU (2005) In Journal of Solid State Chemistry 178(11). p.3471-3475
Abstract

The new compound CuSb2O3Br crystallize in the monoclinic space group Cc. The unit cell parameters are a=7.9189(15)Å, b=13.7105(10)Å, c=19.048(2)Å, β=90°, Z=16. The crystal structure is solved from single crystal data, R=0.0490. The compound show a layered structure with slabs from cubic Sb2O3 interspersed in between puckered layers of CuBr. The Sb(III) atoms have tetrahedral [SbO3E] coordination where E is the 5s2 lone pair, these units build up Sb4O4E6 cages. The CuBr layers resemble those in hexagonal CuBr but the Cu(I) ions have actually tetrahedral [CuBr3O] coordination. The Cu-O bonds link the Sb4O 6... (More)
