The process includes forming a mixture comprising a first precursor and a second precursor, the first precursor comprising copper, the second precursor comprising a phosphine. The process further includes introducing a third precursor with the mixture to form the bimetallic structure, the third precursor comprising a Group 8-10 metal, the bimetallic structure comprising copper (Cu), the Group 8-10 metal (M), phosphorous (P), and nitrogen (N), the bimetallic structure having the formula (Cu).sub.a(M).sub.b(P).sub.c(N).sub.d, wherein a molar ratio of a:b is from about 1:99 to about 99:1, and a molar ratio of a:(c+d) is from about 500:1 to about 1:1.

An electrochemical device capable of more sufficiently preventing swelling due to generation of a gas such as carbon dioxide and decomposition of a lithium salt while having a simple structure. The electrochemical device includes a non-aqueous electrolytic solution, wherein the non-aqueous electrolytic solution contains a metal-organic framework containing: an azole-based organic molecule optionally having a hydrophobic group, and a metal atom.

The invention relates to a method for producing, amongst other things, amino-acid and/or hydroxycarboxylic-acid metal chelates, a solvent-free mixture of at least one metal oxide, metal hydroxide, metal carbonate or oxalate, and the solid organic acid is subjected to intensive mechanical stress. According to the invention, this is done in that the reaction partners are introduced in particle form into a fluid stream of a fluid-bed countercurrent mill operating without grinding elements, wherein mechanical activation of at least one of the reaction partners is effected by collision processes within a reaction chamber formed in a region of the fluid stream, and a solid body reaction to form the metal chelate is triggered. The novel method operates very energy-efficiently and with a high specific yield. It leads to a product having compact particles in the small, single-digit micrometer range having a comparatively narrow particle sizc distribution and a large surface. The product is homogenous and very pure. Thermal loading or decomposition of the organic chelate ligands, in particular of the amino acids, is likewise avoided, as are contaminants from milling and grinding element abrasion.

Compositions may comprise symmetrical and asymmetrical pyridine-containing transition metal-complexes having appended group 13 Lewis acids positioned on the pyridine-containing ligands of the transition metal-complex such that the group 13 Lewis acid may be near the catalytic site, thereby allowing the appended group 13 Lewis acid to function more efficiently in promoting formation of a catalytically active species. Catalysts systems may comprise these symmetrical and asymmetrical pyridine-containing transition metal-complexes and methods of preparing polyolefins may use these catalyst systems.
