Abstract

The Ni(II) complex of the ligandcis-1,2[bis(diphenylphosphino)ethylene] (VPP), [Ni(VPP)2Br]BPh4, crystallizes in the orthorhombic space groupP2121,2, witha=25.971(6),b=24.508 (6),c=19.642(5) Å,Z=8. The structure was determined by the procedure DIRDIF from Cu Kα automatic diffractometer X-ray data and refined by block-diagonal least-squares toR=11% for 5572 reflections. A question on the space group assignment betweenP21212 andP212121 was resolved only after the complete structure had been determined. The detailed crystal and molecular structure is presented.
