Crystal structure of pyridinium nonabromodiantimonate(III) dibromide

Abstract

Pyridinium nonabromodiantimonate(III), (C5H5NH)5(SbIII2Br9)(Br)2, has been prepared and its crystal structure has been determined and refined by Patterson, Fourier, and full-matrix least-squares techniques to a final R of 0·109. The crystals were monoclinic, space group B2m with a= 18·01, b= 30·14, c= 7·82 A°, β= 95·02° and Z=4.

Each [Sb2Br9]3– anion has the form of two distorted SbBr6 octachedra sharing a face : the average Sb–Br distances to the bridging and terminal bromines are 3·00 and 2·63 Å, respectively. There are two bromide ions per formula unit that appear to be for packing purposes only.
