A family of hydride complexes of rhodium. Crystal structure of the paramagnetic rhodium(III)–rhodium(II) complex [(triphos)Rh(µ-H)3Rh(triphos)](BPh4)2·DMF [triphos = MeC(CH2PPh2)3, DMF = dimethylformamide]
Abstract
A family of rhodium hydrides including mono- and bi-cuclear, mono- and poly-hydride, diamagnetic and paramagnetic members has been prepared; the structure of the paramagnetic rhodium hydride [(triphose)Rh(µ-H)3Rh(triphos)](BPh4)2·DMF [triphos = MeC(CH2PPh2)3, DMF = dimethylformamide] has been established by X-ray methods; three hydride ligands bridge two rhodium atoms which are separated by a short distance [2.644(1)Å].
