Dinuclear and Mononuclear Rhenium Coordination Compounds upon Employment of a Schiff-Base Triol Ligand: Structural, Magnetic, and Computational Studies

Abstract: The 1:1 reaction of trans-[ReIIICl3(PPh3)2­(MeCN)] with 2-(β-naphthalideneamino)-2-hydroxymethyl-1-propanol, H3L, in toluene gave the dinuclear complex [ReIII 2Cl4(HL)­(PPh3)]­·2C7H8 (1·2C7H8), while the 1:2 reaction led to the formation of complex [ReIVCl2(HL)­(PPh3)] (2). In both species, the Schiff-base ligand exists in its doubly deprotonated form, HL2–, forming chelate rings around the metallic centers. In addition, 1·2C7H8 displays a unique triple metal-to-metal bond between the two trivalent rhenium ion… Show more

“…54 Furthermore, no signal was observed in the continuous-wave X-band EPR spectrum of 1-Cl in frozen toluene at 10 K, additional evidence that 1-Cl and the rest of the 1-X series exhibit non-Curie paramagnetism. The presence of shifted, yet sharp, NMR spectral peaks has been reported for several other rhenium(III) complexes, typically with octahedral or pseudo-octahedral geometries 1,6,7,[16][17][18][19][20]55 and has been attributed to the presence of TIP.…”

“…Instead, the spin nature of the ground and excited states is likely more important in influencing the overall magnitude of TIP in a complex. Considering the observation of notable TIP effects in a number of other heavy octahedral d 4 and square-planar d6…”
