Question:
(a) The electronic absorption spectrum of [Ni(DMSO)6]2+ (DMSO=Me2SO) exhibits three absorptions at 7728, 12970 and 24 038 cm−1. Assign these absorptions.
(b) CuF2 has a distorted rutile structure (four Cu—F = 193 pm and two Cu—F = 227 pm per Cu centre); [CuF6]2− and [NiF6]3− are distorted octahedral ions. Explain the origins of these distortions.
(c) Dissolution of vanadium metal in aqueous HBr leads to a complex ‘VBr3·6H2O’. X-ray diffraction data reveal that the compound contains a complex cation containing a centre of symmetry. Suggest a formulation for the compound, and a structure for the cation.
