Popis:	The title compound has been prepared and its crystal structure determined by the heavy-atom method from diffractometer data; it was refined by full-matrix least-squares to R 0·045 (949 independent observed reflections). Crystals are monoclinic, space group P21, a= 8·834(2), b= 16·090(4), c= 6·596(1)A, β= 109·78(1)°, Z= 2.Mean distances are: ReIV–As 2·560(4), ReIV–Cl 2·32(1)A. The geometry is considerably distorted from octahedral; this is generally true for [M (bidentate)(monodentate)4]x± compounds and a repulsion model has been developed to account for this.
