Heterobimetallic NiZn complexes featuring metal centers in distinct coordination environments have been synthesized using diimine–dioxime ligands as binucleating scaffolds. A tetramethylfuran-containing ligand derivative enables a stable one-electron-reduced S 1⁄4 1/2 species to be accessed using Cp2Co as a chemical reductant. The resulting pseudo-square planar complex exhibits spectroscopic an...

The title compound, [FePt(C(9)H(9)NO(2)S)(C(18)H(15)P)(C(25)H(22)P(2))(CO)(3)], represents a rare example of an isonitrile-bridged heterobimetallic complex (here Pt and Fe) and is an inter-esting precursor for the preparation of heterodinuclear μ-amino-carbyne complexes, since the basic imine-type N atom of the μ(2)-C=N-R ligand readily undergoes addition with various electrophiles to afford im...

The C3-symmetric uranium(iv) and cerium(iv) complexes Me3SiOM(OArP)3, M = U (1), Ce (2), OArP = OC6H2-6-tBu-4-Me-2-PPh2, have been prepared and the difference between these 4f and 5f congeners as initiators for the ring opening polymerisation (ROP) of l-lactide is compared. The poorly controlled reactivity of the homoleptic analogue U(OArP)4 (3) demonstrates the importance of the M-OSiMe3 initi...

A new sequential metalation strategy that enables the assembly of a more robust reduced symmetry heterobimetallic [PdPtL 4 ] 4+ cage C is reported. By exploiting low-symmetry ditopic ligand ( L ) that...

Single diastereomer, diamagnetic, octahedral Fe(II) tris chelate complexes are synthesised that contain three pendant pyridine proligands pre-organised for coordination to a second metal. They bind Cu(I) and Ag(I) with coordination geometry depending on the identity of the metal and the detail of the ligand structure, but for example homohelical (ΔFe,ΔCu) configured systems with unusual trigona...

The reaction of lithiated picolines and [TiCl3(η(5)-C5Me5)] leads to several bridging or terminal imido compounds, each of which can be selectively formed by controlling the stoichiometry and temperature. Specifically, the dinuclear imido-bridged [TiCl(η(5)-C5Me5)(μ-NR)]2 (1a, NR = 2-imido-3-picoline; 1b, NR = 2-imido-5-picoline) species and the unusual Ti-Li imido-amido heterobimetallic comple...

Heterobimetallic polymers: the best of both worlds? The copolymers electrosynthesized in this work can benefit from conducting polymer structure and presence two metals. Their potential application sensing ascorbic acid was also explored.

The effect of modifying the N-aryl substituent (aryl = mesityl vs. m-xylyl) of the phosphinoamide ligands linking Zr and Co in tris(phosphinoamide)-linked heterobimetallic complexes has been investigated. Treatment of the metalloligand ((i)Pr2PNXyl)3ZrCl (2) (Xyl = m-xylyl) with CoI2 affords the iodide-bridged product ICo((i)Pr2PNXyl)2(μ-I)Zr(η(2-i)Pr2PNXyl) (3) rather than the C3-symmetric iso...
