Flexible anionic metal-organic frameworks (MOFs) are transformed into neutral heterobimetallic systems via single-crystal-to-single-crystal processes invoked by cation insertion. These transformations are directed by cooperative bond breakage and formation, resulting in expansion or contraction of the 3D framework by up to 33% due to the flexible nature of the organic linker. These MOFs display...

The reactions of [CpMoH(κ(3)-P4)] (2; P4 = meso-o-C6H4(PPhCH2CH2PPh2)2) with protic acids gave [CpMo(κ(4)-P4)](+) (4(+)) via the intermediary formation of [CpMoH2(κ(3)-P4)](+). Treatment of 2 with iodine provided the cationic complex [CpMoHI(κ(3)-P4)][I] (5[I]). Early-late heterobimetallic complexes of the type [CpMoH(μ-P4-1κ(3):2κ)MLnCl] (MLn = Ru(Hmb)Cl (6), Ir(η(5)-C5Me5)Cl (7), Rh(cod), Ir(...

The preparation and applications of heterobimetallic complexes continue to occupy researchers in the fields of organometallic, main group, and coordination chemistry. This interest stems from the promise these complexes hold as precursors to materials, reagents in synthesis and as new catalysis. Here we survey and organise the state-of-the-art understanding of the TM-H-M linkage (M = Mg, Zn, Al...

The first heterobimetallic lactide ROP catalysts based on two divalent metals outperform the homobimetallic analogues, attributed to increased Lewis acidity of Mg or Ca (monomer coordination) and enhanced polarity Zn–Et/OR (propagation).

A binuclear macrocyclic ligand containing dissimilar N(amine)2O2 and N(imine)2O2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor L1H2 with 1,3-diaminopropane. The ligand includes two propionitrile pendant arms on the amine nitrogen atoms. The homobimetallic com...

Synthetic, spectroscopic and antimicrobial aspects of some fertility inhibitor heterobimetallic complexes have been carried out. These heterobimetallic chelates [M(C(5)H(5)N(3))(2)M(2)'(R)(4)]Cl(2) (M = Pd or Pt and M' = Si, Sn, Ti and Zr) have been successfully synthesinzed via the reaction of M(C(5)H(7)N(3))(2)Cl(2) with group four or fourteen dichlorides in 1:2 stoichiometric proportions. Th...
