Oxovanadium(IV) Thiocarboxylate Paddlewheels Containing Ancillary Group 10 Metals: A Comparative Study on Pd and Pt Derivatives.

ABSTRACT: Vanadyl-containing paddlewheel structures have recently joined the pool of molecular spin systems showing respectable coherence times (T_m). We extended the investigation of [PtVO(SOCR)₄] (R = Me, Ph) by synthesizing the corresponding Pd derivatives. Crystals of [PdVO(SOCMe)₄] and [PdVO(SOCPh)₄]·DCM are isomorphous to their Pt analogues and comprise staggered and square dimers, respectively. For both Group 10 metals, M···M' contacts in staggered dimers promote a stronger antiferromagnetic coupling than M···S' contacts in square dimers, with Pd complexes showing a slightly more effective interaction consistent with DFT predictions. In solution, the paddlewheels exist in monomeric form and undergo a quasi-reversible one-electron reduction, mo
