Author is Lieberman, Craig M.; Wei, Zheng; Filatov, Alexander S.; Dikarev, Evgeny V..

A new series of heteroleptic bismuth-transition metal β-diketonates [BiM(hfac)3(thd)2] (M = Mn (1), Co (2), and Ni (3); Hhfac = hexafluoroacetylacetonate, Hthd = tetramethylheptanedionate) with Bi:M = 1:1 ratio have been synthesized by stoichiometric reactions between homometallic reagents [BiIII(hfac)3] and [MII(thd)2]. On the basis of anal. of the metal-ligand interactions in heterometallic structures, the title compounds were formulated as ion-pair {[BiIII(thd)2]+[MII(hfac)3]-} complexes. The direct reaction between homometallic reagents proceeds with a full ligand exchange between main group and transition metal centers, yielding dinuclear heterometallic mols. In heteroleptic mols. 1-3, the Lewis acidic, coordinatively unsaturated BiIII centers are chelated by two bulky, electron-donating thd ligands and maintain bridging interactions with three oxygen atoms of small, electron-withdrawing hfac groups that chelate the neighboring divalent transition metals. Application of the mixed-ligand approach allows one to change the connectivity pattern within the heterometallic assembly and to isolate highly volatile precursors with the proper Bi:M = 1:1 ratio. The mixed-ligand approach employed in this work opens broad opportunities for the synthesis of heterometallic (main group-transition metal) mol. precursors with specific M:M’ ratio in the case when homoleptic counterparts either do not exist or afford products with an incorrect metal:metal ratio for the target materials. Heteroleptic complexes obtained in this study represent prospective single-source precursors for the low-temperature preparation of multiferroic perovskite-type oxides.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called CVD of thin oxygen permeable membrane films, published in 2003, which mentions a compound: 14481-08-4, mainly applied to oxide membrane CVD oxygen permeation, COA of Formula: C22H38NiO4.

Membranes with high mixed oxygen-ionic and electronic conductivity are of great interest for oxygen separation and catalytic membrane reactors for partial oxidation of hydrocarbons. In the diffusion regime oxygen flow through membrane is proportional to its reciprocal thickness and gas tight thin films are most promising for applications. In a single source (aerosol- and flash evaporation) CVD equipment using the mixtures of THD compounds as precursors a number of mixed-conductor layers, (La,Sr)(Ga,Fe)O3, (La,Sr)(Co,Fe)O3, La2NiO4 were deposited with a thickness 3-30 μm and typical deposition rate 10 μm/h. As substrates, various porous flat and tubular materials with a pore size up to 10 μm were tested. The film composition, microstructure and gas tightness were studied. Using post-annealing with oxide fluxes the membranes of the gas tightness high enough for applications were obtained.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Chelate Effect in the Gas Phase. The Complexes of Ni(2,2,6,6-tetramethyl-3,5-heptanedionate)2 with Bidentate Ligands》. Authors are Emmenegger, Franzpeter; Schlaepfer, Carl Wilhelm; Stoeckli-Evans, Helen; Piccand, Michel; Piekarski, Henryk.The article about the compound:Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II)cas:14481-08-4,SMILESS:CC(C)(C1=O[Ni+2]2(O=C(C(C)(C)C)[CH-]1)O=C([CH-]C(C(C)(C)C)=O2)C(C)(C)C)C).Safety of Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II).

When a bidentate ligand L-L is added to the square planar Ni(tmhd)2 (tmhd = tetramethylheptanedionate), octahedral Ni(tmhd)2L-L (L-L = tetramethylethylenediamine (TEME), 2,2-bipyridine, dimethylaminomethoxyethane (MAO)) are formed. This reaction was studied by visible spectroscopy in toluene at 25° and in the gas phase between 150 and 350°. It allows the comparison on one hand of the chelate effect of three ligands forming five-membered chelate rings: (i) the flexible N-N ligand TEME; (ii) the rigid N-N ligand bpy; (iii) the flexible N-O ligand MAO. However, it allows the comparison of these ligands with the six-membered chelate ring-forming N-N ligand 1,3-tetramethylpropylenediamine (TEMP). From the temperature dependence of the gas-phase stability constants, enthalpies and entropies of the complex-forming reactions were derived. As there are no solvation effects in the gas phase, the reaction enthalpies are the metal-ligand bond enthalpies. This is of particular interest for the hemilabile ligand MAO. For the N-N ligands, the stability of the metal-ligand bonds decreases in the order TEME > bpy > TEMP. The entropy of the complex formation with the two flexible ligands TEME and MAO is the same, while it is slightly more pos. for the rigid bpy and a lot more pos. for TEMP. ΔformG°298 of the complexes is more neg. in the gas phase than in solution because the solvation energy of the reactants is more neg. than the solvation energy of the products. This is shown in detail for the formation of Ni(tmhd)2bpy where data of a complete thermodn. cycle are presented.

The interaction of pyrrole, pyrrolidine, furan, THF, thiophene, and tetrahydrothiophene with GdL3 and NiL2 (L = 2,2,6,6-tetramethylheptane-3,5-dionate) was studied by determination of electron-nuclear spin-lattice relaxation times for 13C in natural abundance. The results indicate complex formation between GdL3 and pyrrolidine and THF, and between NiL2 and pyrrolidine, THF, and tetrahydrothiophene. Competition experiments gave the relative affinities of the metal chelates for different ligand donor atoms: N > O > S for GdL3, and N > O ≈ S for NiL2.

UV-visible spectroscopy shows very strong bands in the UV region consistent with ligand centered π → π* transitions. The electrochem. studies of 1-6 reveal oxidation to Ni(III). The [Ni(tmhd)2(L-L)] 1-3 are more easily oxidized by ∼300 mV and are quasi-reversible whereas for the [Ni(dbm)2(L-L)] series only complex 6 shows significant reversibility. X-ray crystallog. studies were conducted in the case of [Ni(dbm)2(phen)] 5 and [Ni(dbm)2(dmae)] 6.
