Heme-containing nitrite reductases bind and activate nitrite by a mechanism that is proposed to involve interactions with Brønsted acidic residues in the secondary coordination sphere. To model this functionality using synthetic platforms that incorporate a Lewis acidic site, heterobimetallic CoMg complexes supported by diimine-dioxime ligands are described. The neutral (μ-NO2)CoMg species 3 is...

Five heterobimetallic ReI/AuI and a tri-metallic ReI/AuI/ReI species following the formulas fac-[ReCl (CO)3(N^N^CAuR)]0/+ [(fac-[ReCl (CO)3(N^N^C)])2Au]+, where R is either iodide (1), phenylacetylene (2), dodecanethiol (3), 2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranose (4), JohnPhos (5) N^N^C fused imidazo[4,5-f]-1,10-phenanthroline heterotopic ligand, were synthesised fully characterised by...

Starting from heterotopic multidentate ligand 2,2'-(1,2-phenylenedisulfanediyl)diacetic acid, (RS,RS,RS,RS/SS,SS,SS,SS)-[Ag{1,2-C6H4(SCH2COOH)2-κ2S,S'}2]BF4 (1) was prepared and further used as a building block for the synthesis of heterobimetallic Ag-Cd coordination polymer [Ag2Cd2{1,2-(OOCCH2S)2C6H4}3 (H2O)3·5H2O]n (2). Both complexes were characterized by X-ray structure analysis and convent...

The remarkably distinct reactivity of hydridozinc heterobimetallic cubanes [(HZnOtBu)4-n(thf LiOtBu)n] 1a-1d towards CO2 is reported--the hydride transfer from Zn-H to CO2 is drastically accelerated in the presence of Li ions in 1b-1d which led to the respective metal formate hydrates; the systems are inspiring models for the selective conversion of water gas into formates on lithium-promoted Z...

Two novel low-dimensional molecular magnetic materials were prepared by a self-assembling of 3dand 5d-metal complexes. These are the first neutral heterobimetallic cyanobridged compounds involving one anisotropic Mn(III) Schiff base complex and one octacyanotungstate(V) per molecular unit. A slow diffusion of the constituents’ solutions leads to a formation of the 0D crystalline complex 1 due t...

We present a straightforward and generally applicable synthesis route for cofacially linked homo- heterobimetallic porphyrin complexes. The protocol allows the of unsymmetrical aryl-based meso-meso as well β-meso-linked porphyrins. Our method significantly increases overall yield published compound known o-phenylene-bisporphyrin (OBBP) by factor 6.8. Besides 16 novel homobimetallic complexes co...

Cp*IrH4 reacts with Hf(Np)4 (Np = CH2C(CH3)3) to yield the heterobimetallic complex [Hf(Np)3(μ-H)3IrCp*], 2. Treatment of 2 neopentyl lithium (NpLi) results in nucleophilic addition a moiety onto Hf center, restoring and displacing Cp*IrH3– iridate fragment. By contrast, treatment tantalum/iridium analogue [Ta(Np)3IrH2(Cp*)], 1, NpLi triggers α-hydrogen abstraction at Ta–neopentyl leads formati...

The lithiation of the NHC ligand backbone in Cp(CO)2Mn(IMes) followed by transmetalation on C4 carbenic position with Cp(CO)2FeI led to heterobimetallic complex Cp(CO)2Mn(?-dIMes)Fe(CO)2Cp bearing anionic ditopic imidazol-2,4-diylidene dIMes ligand. Subsequent treatment later TfOH induced a selective decoordination [Cp(CO)2Mn] fragment form cationic abnormal [Cp(CO)2Fe(aIMes)](OTf), which was f...
