Question

i) [Ni(OH2)6]Cl2, A, is pale green and has a magnetic moment of 2.83 B.M. It reacts with an excess of PPh3 in ethanol to yield a dark green solid, B, which has a magnetic susceptibility of 0.00334 cm3 mol-1 at 298 K. Reaction of A with an excess of P(n-Bu)3 produces a bright red diamagnetic solid C. Identify B and C and account for the magnetic properties of A, B and C.
