Abstract
The new PtVO(SOCR)4lantern complexes,1(R = CH3) and2(R = Ph) behave as neutral O-donor ligands to Ln(OR)3with Ln = Ce, Nd. Four heterotrimetallic complexes with linear {LnOVPt} units were prepared: [Ln(ODtbp)3{PtVO(SOCR)4}] (Ln = Ce,3Ce(R = CH3),4Ce(R = Ph); Nd,3Nd(R = CH3),4Nd(R = Ph); ODtbp = 2,6-ditertbutylphenolate). Magnetic characterization confirms slow magnetic relaxation behaviour and suggests antiferromagnetic coupling across {Ln-OV} in all four complexes, with variations tunable as a function of Ln and R.
